C2H2 zinc finger (ZF) transcription factors (TFs) are among the most abundant and versatile regulatory proteins, playing critical roles in development, differentiation, apoptosis, stress response, and immune regulation. In livestock, especially within the Bovidae family, these TFs regulate gene expression linked to economically important traits such as growth, reproduction, milk production, and disease resistance. However, genome-wide identification of C2H2-ZF TFs in Bovidae remains limited due to the lack of specialized computational tools. To address this, we developed DeepBovC2H2-ZF, a deep learning-based framework for predicting C2H2-ZF TFs using only protein sequence information. The model was trained on a curated dataset of validated C2H2-ZF and non-C2H2-ZF TFs, utilizing sequence-derived features that capture the unique domain signatures. DeepBovC2H2-ZF achieved high prediction accuracy, sensitivity, and specificity, outperforming traditional machine learning models. A correctly predicted C2H2-ZF protein, Krüppel-like factor 4 (KLF4), was further validated through molecular docking and three independent molecular dynamics (MD) simulations of both the protein and its DNA-bound complex. The simulations confirmed structural stability and strong DNA-binding affinity, supporting the reliability of DeepBovC2H2-ZF for functional genomics studies in Bovidae.
C2H2锌指(ZF)转录因子(TFs)是细胞发育、分化、细胞凋亡、应激反应和免疫调节等方面数量最多、用途最广的调控蛋白之一。在牲畜中,特别是牛科动物,这些tf调节与经济上重要性状(如生长、繁殖、产奶量和抗病能力)相关的基因表达。然而,由于缺乏专门的计算工具,牛科C2H2-ZF TFs的全基因组鉴定仍然有限。为了解决这个问题,我们开发了DeepBovC2H2-ZF,这是一个基于深度学习的框架,仅使用蛋白质序列信息来预测C2H2-ZF TFs。该模型在经过验证的C2H2-ZF和非C2H2-ZF tf的策划数据集上进行训练,利用序列派生的特征捕获唯一的域签名。DeepBovC2H2-ZF具有较高的预测精度、灵敏度和特异性,优于传统的机器学习模型。通过对C2H2-ZF蛋白及其dna结合复合物的分子对接和三个独立分子动力学(MD)模拟,进一步验证了正确预测的C2H2-ZF蛋白kr样因子4 (KLF4)。模拟结果证实了结构稳定性和较强的dna结合亲和力,支持了DeepBovC2H2-ZF用于牛科动物功能基因组学研究的可靠性。

Background

Hyperthyroidism frequently impairs liver function through oxidative stress, inflammation, and apoptosis. Effective hepatoprotective therapies remain limited, targeting the effects of natural agents such as Diceratella Elliptica. The current study assessed the hepatoprotective efficacy of Diceratella Elliptica (DE) in an experimental model of L-thyroxin–induced hyperthyroidism.

Methods

This study performed on 40 male albino rats randomly allocated equally into five groups, control group (HT), L-thyroxin alone (orally, 600 mg/kg daily for 12 days) or in combination with propyl Thiourcil (PU) (intraperitoneally, 10 mg/kg daily for 15 days), and Diceratella Elliptica extract in 200 mg/kg and 400 mg/kg (orally, with a daily dose for 15 days). Hepatic function (ALT, AST, total protein), oxidative stress markers (SIRT1, Nrf2, MDA, NO, GSH, SOD and CAT), inflammatory markers (HMGB1, TLR4, NFκ-B, IL-6 and TNF-α), and apoptotic marker (Caspase-3) were measured, alongside histopathological evaluation.

Results

Hyperthyroid rats exhibited marked hepatic injury, with significant elevations in ALT (+85 %), AST (+72 %), MDA (+90 %), NO (+65 %), TNF-α (+70 %), IL-6 (+68 %), and Caspase-3 (+60 %) (P < 0.05), accompanied by substantial reductions in SIRT1 (−45 %), Nrf2 (−40 %), GSH (−50 %), SOD (−42 %), and CAT (−38 %) compared to control. Treatment with D. Elliptica (especially 400 mg/kg) significantly restored liver function, normalizing ALT and AST by nearly 50 %, enhancing antioxidant enzyme activities by 35–55 %, and down-regulating inflammatory and apoptotic markers (p < 0.05). Histological examination revealed restoration of hepatic cords, reduced inflammatory infiltration, and preserved hepatocyte morphology.

Conclusion

Diceratella Elliptica exerts potent hepatoprotective activity against hyperthyroidism-induced hepatic injury. Its concurrent activation of SIRT1 and Nrf2, along with suppression of NF-κB–mediated inflammation and Caspase-3–dependent apoptosis, suggests modulation of the oxidative stress–inflammation–apoptosis axis. These findings support Diceratella Elliptica as a promising natural therapeutic candidate for thyroid-related liver dysfunction.
背景:甲亢经常通过氧化应激、炎症和细胞凋亡损害肝功能。有效的肝保护疗法仍然有限,主要针对天然药物的作用,如椭圆笛角霉。本研究在l -甲状腺素诱导的甲状腺功能亢进的实验模型中评估了椭圆笛角藻(DE)的肝保护作用。方法将40只雄性白化大鼠随机分为5组:对照组(HT)、l -甲状腺素单用组(口服,600 mg/kg / d,连用12 d)或与丙硫脲(PU)联用组(腹腔注射,10 mg/kg / d,连用15 d)和椭圆角蒿提取物(200 mg/kg、400 mg/kg,口服,连用15 d)。测定肝功能(ALT、AST、总蛋白)、氧化应激标志物(SIRT1、Nrf2、MDA、NO、GSH、SOD、CAT)、炎症标志物(HMGB1、TLR4、NFκ-B、IL-6、TNF-α)、凋亡标志物(Caspase-3),并进行组织病理学评价。结果甲亢大鼠表现出明显的肝损伤,ALT(+ 85%)、AST(+ 72%)、MDA(+ 90%)、NO(+ 65%)、TNF-α(+ 70%)、IL-6(+ 68%)、Caspase-3(+ 60%)显著升高(P < 0.05), SIRT1(- 45%)、Nrf2(- 40%)、GSH(- 50%)、SOD(- 42%)、CAT(- 38%)显著降低。黄芪(特别是400 mg/kg)可显著恢复肝功能,使ALT和AST恢复正常近50%,使抗氧化酶活性提高35 - 55%,并下调炎症和凋亡标志物(p < 0.05)。组织学检查显示肝索恢复,炎症浸润减少,肝细胞形态保存。结论椭圆角蒿对甲亢性肝损伤具有较强的保肝作用。它同时激活SIRT1和Nrf2,同时抑制NF-κ b介导的炎症和caspase -3依赖性的凋亡,表明氧化应激-炎症-凋亡轴受到调节。这些发现支持椭圆笛角藻作为一种有希望的天然治疗甲状腺相关性肝功能障碍的候选药物。

The prevalence of hepatotoxicity has sharply increased worldwide in recent decades. Our study aimed to enhance quercetin’s effectiveness against paracetamol (PCM)-induced hepatotoxicity using a quercetin liposome nano formulation. The quercetin liposome (QL) nano formula was fabricated by applying the thin-film hydration method. It was examined via dynamic light scattering, confirmed with a transmission electron microscope (TEM), and followed by assessments of drug-loading capacity, encapsulation efficiency (EE%), and Fourier transform infrared (FTIR) spectroscopy. The release features and cell cytotoxicity were also assessed. The in vivo parameters were completed. We effectively synthesized and characterized the quercetin liposome nanoformula with a 501.9 nm particle size and a –22.8 mV zeta potential. TEM imaging showed that quercetin liposomes were spherical. The EE% for the optimized formulation was 77.1 %. FTIR test confirmed the quercetin liposome spectra. Sustained release behavior of about 67.45 % of quercetin was released from liposomes by 24 h. The IC50 value was reduced from 71.32 µg/ml to 51.28 µg/ml for quercetin and quercetin-loaded liposomes. For the in vivo study, quercetin liposome improved all the altered biochemical markers, alleviating the levels of Malondialdehyde (MDA), Nitric oxide (NO), Superoxide dismutase (SOD), and Glutathione peroxidase (GPx), and upregulating Nuclear factor erythroid 2-related factor 2 (Nrf2) with a downregulation of Kelch-like ECH-associated protein 1 (Keap1), Nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB), and p38 Mitogen-activated protein kinase (P38 MAPK) gene expression that paralleled the histopathological amelioration. Our results suggested that the quercetin liposome nano formulation had potent hepatoprotective activity through ameliorating biochemical indicators, oxidative stress markers, upregulation of anti-apoptotic genes, and improvement in the histopathological index.
近几十年来,肝毒性在世界范围内急剧增加。本研究旨在利用槲皮素脂质体纳米制剂增强槲皮素抗扑热息痛(PCM)诱导的肝毒性。采用薄膜水化法制备槲皮素脂质体(QL)纳米配方。通过动态光散射检测,透射电子显微镜(TEM)确认,随后评估载药量,包封效率(EE%)和傅里叶变换红外光谱(FTIR)。并对其释放特性和细胞毒性进行了评价。完成体内参数测定。我们有效地合成了槲皮素脂质体纳米配方,其粒径为501.9 nm, zeta电位为-22.8 mV。透射电镜显示槲皮素脂质体呈球形。最佳配方的EE%为77.1%。FTIR测试证实槲皮素脂质体光谱。槲皮素和负载槲皮素脂质体的IC50值从71.32µg/ml降至51.28µg/ml。在体内研究中,槲皮素脂体改善了所有改变的生化指标,减轻了丙二醛(MDA)、一氧化氮(NO)、超氧化物歧化酶(SOD)和谷胱甘肽过氧化物酶(GPx)的水平,上调了核因子红细胞2相关因子2 (Nrf2),下调了kelch样ech相关蛋白1 (Keap1)、活化B细胞的核因子kappa轻链增强子(NF-κB)。p38丝裂原活化蛋白激酶(p38 MAPK)基因表达与组织病理改善相似。结果表明,槲皮素脂质体纳米制剂通过改善生化指标、氧化应激标志物、上调抗凋亡基因和改善组织病理学指标,具有较强的保肝活性。

Carotenoids are potent antioxidants and high-value bioactive compounds that green microalgae can efficiently synthesize. This study aimed to enhance carotenoid production in Chlorococcum humicola TISTR 8551 using a two-stage cultivation strategy in a 10-L air-lift photobioreactor (ALPBR), separating biomass accumulation and stress induction phases. During the “green stage” (9 days), cells were grown in modified BG-11 medium (N:P ratio 31:1) under 3,500 Lux white LED light with varying CO2 concentrations (1–3 % v/v) to maximize biomass yield. In the subsequent “red stage” (15 days), environmental stressors, including elevated salinity and intensified light exposure, were applied to stimulate carotenoid biosynthesis. The highest total carotenoid content (38.72 ± 1.04 mg/L, 0.313 ± 0.018 mg/g biomass) was observed under 3 % CO2 supplementation, likely due to enhanced photosynthetic carbon fixation and improved precursor availability via glucose metabolism. An optimal white light intensity of 25,000 Lux produced 32.03 ± 1.52 mg/L carotenoids. Additionally, the combination of 100,000 Lux white light with 1,600 Lux blue light significantly increased β-carotene content (6.98 ± 0.28 % of total carotenoids), while 2,400 Lux blue light yielded the highest astaxanthin level (5.01 ± 0.18 % of total carotenoids). These results highlight the synergistic effects of CO2 enrichment, spectral light modulation, and stage-specific stress application in promoting targeted carotenoid biosynthesis. This study offers practical insights for optimizing large-scale microalgal pigment production in controlled photobioreactor systems.
类胡萝卜素是绿色微藻能够高效合成的抗氧化剂和高价值生物活性化合物。在10 l气升式光生物反应器(ALPBR)中,采用分离生物量积累阶段和胁迫诱导阶段的两阶段培养策略,提高humicola TISTR 8551的类胡萝卜素产量。在“绿色阶段”(9天),细胞在改性BG-11培养基(N:P比31:1)中生长,在3500 Lux白光LED灯下,以不同的CO2浓度(1 - 3% v/v)最大化生物质产量。在随后的“红色阶段”(15天),环境压力因素,包括盐度升高和光照增强,被用于刺激类胡萝卜素的生物合成。添加3% CO2时,类胡萝卜素总含量最高(38.72±1.04 mg/L, 0.313±0.018 mg/g生物量),这可能是由于光合作用固碳增强和葡萄糖代谢前体利用率提高所致。在25000 Lux的最佳白光强度下,类胡萝卜素的产量为32.03±1.52 mg/L。此外,100,000 Lux白光与1,600 Lux蓝光组合显著提高了β-胡萝卜素含量(占总类胡萝卜素的6.98±0.28%),而2,400 Lux蓝光产生的虾青素含量最高(占总类胡萝卜素的5.01±0.18%)。这些结果强调了CO2富集、光谱光调制和阶段特异性胁迫在促进靶向类胡萝卜素生物合成中的协同作用。该研究为在可控光生物反应器系统中优化大规模微藻色素生产提供了实践见解。

Renal cell carcinoma (RCC) is often associated with metabolic disorders such as type 2 diabetes mellitus (T2DM) and hypertension. While existing research has established connections between these metabolic conditions and RCC, the underlying mechanisms driving RCC followed by pancreatic metastasis remain incompletely understood. Therefore, our study aimed to investigate the complex interplay between metabolic disorders (type 2 diabetes and hypertension) and malignancies (renal cell carcinoma and pancreatic cancer). To investigate the hidden link, we performed an integrative transcriptomic analysis. The analysis focuses only on T2DM and hypertension to identify a connection with the RCC pathway. Our analysis revealed that 190 significantly upregulated genes, of which MET emerged as a master regulator in RCC, while KRAS was the key regulator in pancreatic cancer. Furthermore, we identified key microRNAs (has-mir-1-3p, has-mir-16-5p, and has-mir-455-3p) and transcription factors (MBD1, TFDP1, and KLF9) regulate these targets. Additionally, we identified and validated CDC42, PTPN11, TGFB3, and MET as potential prognostic or theragnostic biomarkers. MET, KRAS, and PIK3CD emerged as the most promising therapeutic targets against a panel of 28 repurposable inhibitory drugs. The genetic and immune association suggested that CD8 + T cells are the key immune infiltrate significantly associated with poor survival outcomes in RCC and pancreatic cancer patients.

Our study provides critical insights into the statistically significant associations between metabolic disorders and malignancies, emphasizing the potential of tailored therapies alongside shared therapies in managing RCC and its progression to pancreatic metastasis.
肾细胞癌(RCC)通常与代谢性疾病如2型糖尿病(T2DM)和高血压有关。虽然现有的研究已经建立了这些代谢条件与RCC之间的联系,但驱动RCC随后胰腺转移的潜在机制仍然不完全清楚。因此,我们的研究旨在探讨代谢紊乱(2型糖尿病和高血压)与恶性肿瘤(肾细胞癌和胰腺癌)之间复杂的相互作用。为了研究隐藏的联系,我们进行了综合转录组分析。该分析仅关注T2DM和高血压,以确定与RCC途径的联系。我们的分析显示,190个基因显著上调,其中MET是RCC的主要调控因子,而KRAS是胰腺癌的关键调控因子。此外,我们确定了关键的microrna (has-mir-1-3p, has-mir-16-5p和has-mir-455-3p)和转录因子(MBD1, TFDP1和KLF9)调节这些靶点。此外,我们鉴定并验证了CDC42、PTPN11、TGFB3和MET作为潜在的预后或诊断生物标志物。MET、KRAS和PIK3CD是对28种可重复使用的抑制药物最有希望的治疗靶点。遗传和免疫关联表明,CD8 + T细胞是与RCC和胰腺癌患者生存预后不良显著相关的关键免疫浸润。突变分析进一步强调了KRAS G12C、G12V和G12D突变的意义,这些突变在RCC和胰腺转移之间是常见的。我们的研究为代谢性疾病和恶性肿瘤之间的统计学意义相关性提供了重要见解,强调了定制治疗和共享治疗在控制RCC及其进展到胰腺转移方面的潜力。

SRC is a proto-oncogene that regulates cell proliferation and survival, and its dysregulation is commonly observed in diverse cancers. While SRC kinase dysregulation is well-established as a cancer driver, the functional consequences of its genetic variants, particularly non-synonymous single-nucleotide polymorphisms (nsSNPs) are not fully understood. Therefore, we employed an integrative computational approach to identify nsSNPs in SRC and analyze their impact on protein function and structure. Out of the 512 missense nsSNPs analyzed, 42 were predicted to be deleterious, with 12 likely to destabilize protein structure. Among these, three mutations, namely W151C (rs746439256), Y419N (rs2147125119), and P465S (rs1251532695), were particularly significant, causing substantial physicochemical changes. Molecular dynamics simulations revealed that these variations reduce protein stability and flexibility, resulting in conformational alterations. Docking study demonstrated that these mutations disrupt the binding interface residues of the SRC-FAK complex and affect dasatinib binding affinity. Additionally, gene expression analysis linked mutated SRC to dysregulation of cancer-related genes, especially in multiple myeloma and uterine cancer, and suggested reciprocal regulation by other mutated genes across malignancies. These findings highlight the oncogenic potential of SRC mutations and pave the way for future population-based studies exploring their role as diagnostic biomarkers, therapeutic targets, and modulators of drug response in personalized cancer treatment.
SRC是一种调节细胞增殖和存活的原癌基因,其失调在多种癌症中都很常见。虽然SRC激酶失调被认为是癌症驱动因素,但其遗传变异,特别是非同义单核苷酸多态性(nssnp)的功能后果尚未完全了解。因此,我们采用综合计算方法鉴定SRC中的nssnp,并分析其对蛋白质功能和结构的影响。在分析的512个错义nssnp中,预计有42个是有害的,其中12个可能破坏蛋白质结构的稳定。其中W151C (rs746439256)、Y419N (rs2147125119)和P465S (rs1251532695)三个突变尤为显著,引起了较大的理化变化。分子动力学模拟显示,这些变化降低了蛋白质的稳定性和灵活性,导致构象改变。对接研究表明,这些突变破坏了SRC-FAK复合物的结合界面残基,影响了达沙替尼的结合亲和力。此外,基因表达分析将SRC突变与癌症相关基因的失调联系起来,特别是在多发性骨髓瘤和子宫癌中,并表明其他突变基因在恶性肿瘤中相互调节。这些发现强调了SRC突变的致癌潜力,并为未来基于人群的研究铺平了道路,探索它们在个性化癌症治疗中作为诊断生物标志物、治疗靶点和药物反应调节剂的作用。

Bitter gourd is recognized for its anticancer and antidiabetic properties, largely attributed to charantin, and is also a rich source of carotenoids, including β-carotene. In this study, considerable variation was observed in both the accumulation and gene expression patterns associated with charantin and β-carotene biosynthesis across diverse genotypes. PVGy-201 exhibited the strongest gene expression profile, with the highest transcript levels for five key genes, including McIDI (∼16,493-fold), McPMK (∼694-fold), and McSE (∼466-fold), which corresponded with the maximum charantin content (38.53 µg/g FW). Similarly, DBGS-2 showed elevated expression of McHMGR1 (∼271-fold) and McMK (∼13-fold), supporting its high charantin accumulation (35.27 µg/g FW). The wild species Momordica balsamina demonstrated strong expression of McHMGR2 and McSE, consistent with charantin content of 29.36 µg/g FW. For β-carotene, DBGS-21-06 recorded peak expression of McPSY (∼17.2-fold), McZDS (∼4.9-fold), and McCHXB (∼2.8-fold), aligning with high carotenoid levels at both edible (18.46 µg/g FW) and ripening (52.31 µg/g FW) stages. Pusa Rasdar showed elevated expression of McZEP (∼6.9-fold) and McPDS (∼10.8-fold), correlating with maximum carotenoid content (19.49 µg/g FW at edible stage and 55.66 µg/g FW at ripening). DBGS-100-0 expressed McLCYE1 (∼2.9-fold) and McLCYE2 (∼3.1-fold), with high carotenoids (15.91 µg/g FW) at the edible stage. Collectively, PVGy-201 and DBGS-2 were identified as promising candidates for charantin enrichment, while DBGS-21-06 and Pusa Rasdar emerged as superior for β-carotene accumulation. These genotype-specific insights provide a molecular framework to support marker-assisted selection, transcriptome-based screening, and metabolic engineering for the development of nutritionally enhanced bitter gourd cultivars with stable metabolite profiles.
苦瓜以其抗癌和抗糖尿病的特性而闻名,这主要归功于charantin,它也是类胡萝卜素的丰富来源,包括β-胡萝卜素。在这项研究中,在不同的基因型中,与charantin和β-胡萝卜素生物合成相关的基因积累和表达模式都有很大的差异。PVGy-201表现出最强的基因表达谱,五个关键基因的转录水平最高,包括McIDI(~ 16,493倍),McPMK(~ 694倍)和McSE(~ 466倍),这与最大charantin含量(38.53µg/g FW)相对应。同样,DBGS-2显示McHMGR1(~ 271倍)和McMK(~ 13倍)的表达升高,支持其高charantin积累(35.27µg/g FW)。野生苦瓜(Momordica balsamina) mcchmgr2和McSE表达较强,与charantin含量29.36µg/g FW一致。对于β-胡萝卜素,DBGS-21-06记录了McPSY(~ 17.2倍)、McZDS(~ 4.9倍)和McCHXB(~ 2.8倍)的峰值表达,在可食用(18.46µg/g FW)和成熟(52.31µg/g FW)阶段均具有高水平的类胡萝卜素。Pusa Rasdar显示McZEP(~ 6.9倍)和McPDS(~ 10.8倍)的表达升高,与最大类胡萝卜素含量(食用期19.49µg/g FW,成熟期55.66µg/g FW)相关。DBGS-100-0表达McLCYE1(~ 2.9倍)和McLCYE2(~ 3.1倍),在食用阶段具有高的类胡萝卜素(15.91µg/g FW)。总的来说,PVGy-201和DBGS-2被认为是charantin富集的有希望的候选物质,而DBGS-21-06和Pusa Rasdar被认为是β-胡萝卜素积累的优势物质。这些基因型特异性的见解为支持标记辅助选择、基于转录组的筛选和代谢工程提供了分子框架,以开发具有稳定代谢物谱的营养增强苦瓜品种。

Amyotrophic lateral sclerosis (ALS) is a prevalent and debilitating neurodegenerative disorder characterized by the selective degeneration of motor neurons. This study aims to unravel the molecular mechanisms underlying ALS through an integrated analysis of drug-target networks and gene expression data. Gene expression datasets related to ALS, including GSE115130 and GSE76220, were retrieved from the GEO database and systematically analyzed. Differential gene expression (DEG) analysis identified key upregulated and downregulated genes, while weighted gene co-expression network analysis (WGCNA) uncovered gene modules associated with ALS pathology. DEG analysis revealed genetic insights into ALS by pinpointing genes potentially involved in disease development and progression. WGCNA provided a systems-level understanding of ALS mechanisms, identifying highly correlated gene clusters and their relationship with clinical ALS characteristics. In the GSE115130 dataset, 6,105 genes were upregulated and 6,069 were downregulated. Conversely, the GSE76220 dataset showed 4,850 upregulated genes and 7,691 downregulated genes. Using the STRING database, a protein–protein interaction (PPI) network was constructed to investigate the functional relationships among ALS-associated genes. The findings highlighted the significant role of the survival motor neuron 1 (SMN1) gene in ALS, particularly in sporadic cases. Additionally, drug-target network mapping identified potential therapeutic targets and candidate drugs, offering valuable insights into the molecular mechanisms of ALS and possible interventions. This integrative approach underscored SMN1 as a novel diagnostic biomarker and potential therapeutic target for ALS, emphasizing its critical role in disease pathogenesis. These findings pave the way for further mechanistic studies and clinical validation, aiming to enhance therapeutic strategies for ALS.
肌萎缩性侧索硬化症(ALS)是一种普遍和衰弱的神经退行性疾病,其特征是运动神经元的选择性变性。本研究旨在通过对药物靶点网络和基因表达数据的综合分析,揭示ALS的分子机制。从GEO数据库中检索与ALS相关的基因表达数据集GSE115130和GSE76220,并进行系统分析。差异基因表达(DEG)分析确定了关键的上调和下调基因,而加权基因共表达网络分析(WGCNA)揭示了与ALS病理相关的基因模块。DEG分析通过精确定位可能参与疾病发展和进展的基因,揭示了ALS的遗传见解。WGCNA提供了对ALS机制的系统级理解,确定了高度相关的基因簇及其与ALS临床特征的关系。在GSE115130数据集中,6105个基因上调,6069个基因下调。相反,GSE76220数据集显示4850个上调基因和7691个下调基因。利用STRING数据库构建蛋白-蛋白相互作用(PPI)网络,研究als相关基因间的功能关系。这些发现强调了存活运动神经元1 (SMN1)基因在ALS中的重要作用,特别是在散发性病例中。此外,药物靶点网络图谱确定了潜在的治疗靶点和候选药物,为ALS的分子机制和可能的干预措施提供了有价值的见解。这种综合方法强调了SMN1作为ALS的一种新的诊断生物标志物和潜在的治疗靶点,强调了其在疾病发病机制中的关键作用。这些发现为进一步的机制研究和临床验证铺平了道路,旨在提高ALS的治疗策略。

Recent advances in design biology, including artificial cells, DNA nanostructures, artificial intelligence (AI)-driven molecular design, biofoundries, and next-generation genome editing, are transforming the health sciences of mind and body (HS-MB). Moving beyond traditional observational paradigms, these technologies enable predictive and design-oriented strategies for regulating stress, emotional health, achieving immune homeostasis, and managing lifestyle-related disorders. Psychological and social factors profoundly influence core physiological systems, including neuroendocrine (hypothalamic–pituitary–adrenal [HPA]) axis and cortisol rhythm, autonomic (vagal tone and heart rate variability), immune (cytokine balance and inflammatory control), metabolic (glucose–insulin regulation), and sleep–circadian systems. Artificial cells serve as controllable models for neurotransmitter signaling, immune interactions, and gut–brain communication, while DNA origami provides programmable nanocarriers that complement lipid nanoparticles (LNPs). Genome-editing innovations—such as prime, base, and epigenome editing—facilitate precise and reversible modulation of psychiatric risk genes, particularly when combined with induced pluripotent stem cell (iPSC) and brain-organoid models. Biofoundries integrate AI into Design–Build–Test–Learn (DBTL) cycles, automating molecular discovery and optimization. Ethical and regulatory considerations, including AI transparency, biocontainment, and dual-use governance, must be incorporated from the outset. Collectively, design biology, when strategically aligned with HS-MB, establishes a foundational framework for twenty-first-century medicine that bridges molecular engineering and holistic well-being.
设计生物学的最新进展,包括人工细胞、DNA纳米结构、人工智能驱动的分子设计、生物铸造厂和下一代基因组编辑,正在改变身心健康科学(HS-MB)。这些技术超越了传统的观察范式,为调节压力、情绪健康、实现免疫稳态和管理与生活方式相关的疾病提供了预测和设计导向的策略。心理和社会因素深刻影响核心生理系统,包括神经内分泌(下丘脑-垂体-肾上腺[HPA])轴和皮质醇节律、自主神经(迷走神经张力和心率变异性)、免疫(细胞因子平衡和炎症控制)、代谢(葡萄糖-胰岛素调节)和睡眠-昼夜系统。人工细胞作为神经递质信号、免疫相互作用和肠-脑通信的可控模型,而DNA折纸提供可编程的纳米载体,补充脂质纳米颗粒(LNPs)。基因组编辑技术的创新,如引物、碱基和表观基因组编辑,促进了精神疾病风险基因的精确和可逆调节,特别是当与诱导多能干细胞(iPSC)和脑类器官模型结合使用时。生物铸造厂将人工智能集成到设计-构建-测试-学习(DBTL)周期中,自动化分子发现和优化。伦理和监管方面的考虑,包括人工智能透明度、生物控制和军民两用治理,必须从一开始就纳入考虑。总体而言,设计生物学,当战略上与HS-MB相结合时,为21世纪的医学建立了一个桥梁分子工程和整体健康的基础框架。

Leukemogenesis fundamentally depends on the interaction between Menin and MLL1 fusion proteins, especially in the context of aggressive mixed-lineage leukemia (MLL)-rearranged subtypes. This interaction can be disrupted to facilitate a focused therapeutic strategy. This study aimed to employ a comprehensive in silico drug repurposing strategy to identify new inhibitors of the Menin-MLL1 interaction. A comprehensive library of FDA-approved pharmaceuticals was subjected to a rigorous screening process utilizing virtual methodologies, clustering techniques, and a machine learning-based model (PSICHIC) to forecast binding affinity, subsequently complemented by molecular docking and an assessment of drug-likeness. Compounds that surpassed the antagonist value of the control (0.97076 kcal/mol) were selected for subsequent molecular docking investigations. The leading candidate, compound 52920501, exhibited a remarkable binding energy of − 8.89 kcal/mol in contrast to the control (DS-1594b), alongside advantageous pharmacokinetic characteristics and electronic stability, as validated by Density Functional Theory (DFT). Consistent docking interactions with critical residues (Asn282, Asp285, Asn244) facilitated by 52920501. Molecular dynamics simulations (300 ns) demonstrated that 52,920,501 sustained a stable interaction with Menin, promoted protein compaction, and reduced structural fluctuations. The MM/GBSA analysis conducted over the final 50 ns of the MD simulation revealed that compound 52,920,501 established a stable protein–ligand complex, exhibiting a final ΔTOTAL energy of − 12.83 kcal/mol. This value is comparable to the control, which recorded − 13.41 kcal/mol, yet demonstrates stronger individual interaction components. The inclusion of entropic contributions indicated a binding free energy (ΔG Binding) of − 4.75 kcal/mol for 52920501, in contrast to + 7.05 kcal/mol for the control, highlighting its enhanced binding thermodynamics. The steered molecular dynamics (SMD) simulations provided additional validation of 52920501′s robust binding affinity, exhibiting a greater resistance (600 kJ/mol/nm) to external pulling forces in comparison to the control. In summary, compound 52,920,501 presents itself as a promising therapeutic candidate, bolstered by persuasive computational data that underscores its potential as a Menin-MLL1 inhibitor. It warrants further exploration through subsequent in vitro and in vivo studies.
白血病的发生从根本上依赖于Menin和MLL1融合蛋白之间的相互作用,特别是在侵袭性混合谱系白血病(MLL)重排亚型的背景下。这种相互作用可以被破坏,以促进集中的治疗策略。本研究旨在采用一种综合的计算机药物再利用策略来鉴定Menin-MLL1相互作用的新抑制剂。通过虚拟方法、聚类技术和基于机器学习的模型(psicic)来预测结合亲和力,随后辅以分子对接和药物相似性评估,fda批准的药物综合库经过了严格的筛选过程。选择超过对照拮抗值(0.97076 kcal/mol)的化合物进行后续分子对接研究。与对照(DS-1594b)相比,先导候选化合物52920501具有- 8.89 kcal/mol的显著结合能,并具有良好的药代动力学特性和电子稳定性,经密度泛函理论(DFT)验证。52920501促进了与关键残基(Asn282、Asp285、Asn244)的一致对接作用。分子动力学模拟(300 ns)表明,52,920,501与Menin保持稳定的相互作用,促进蛋白质压实,减少结构波动。在MD模拟的最后50 ns进行的MM/GBSA分析显示,化合物52,920,501建立了稳定的蛋白质配体复合物,其最终ΔTOTAL能量为−12.83 kcal/mol。该值与对照组(- 13.41 kcal/mol)相当,但显示出更强的个体相互作用成分。熵贡献的加入表明,52920501的结合自由能(ΔG binding)为−4.75 kcal/mol,而对照组的结合自由能为+ 7.05 kcal/mol,表明其结合热力学增强。操纵分子动力学(SMD)模拟进一步验证了52920501的强大结合亲和力,与对照组相比,表现出更大的外部拉力阻力(600 kJ/mol/nm)。综上所述,化合物52,920,501作为一种有前景的候选治疗药物,有说服力的计算数据支持其作为Menin-MLL1抑制剂的潜力。它值得通过随后的体外和体内研究进一步探索。
