Post-traumatic stress disorder (PTSD) is a relatively common but complex mental illness with a range of diverse risk factors. Typical symptoms include the re-experience or avoidance of traumatic events, cognitive impairment, and hypervigilance. While the exact pathogenesis of PTSD is unclear, many studies indicate that epigenetic regulation plays a key role in its development. Specifically, numerous studies have indicated that the levels of histone acetylation and methylation, DNA methylation, and noncoding RNA are altered in PTSD patients. Further to this, natural products have been found to achieve epigenetic regulation of PTSD by regulating the expression of epigenetic enzymes, long noncoding RNA (lncRNA), and miRNA, thereby playing a role in improving PTSD symptoms. To date, however, no epigenetic regulation related drugs have been used in the treatment of PTSD. Furthermore, while natural products that can epigenetically regulate PTSD have received increasing levels of attention, there have not yet been any systematic reports on the topic. Here, we summarized the roles and mechanisms of natural products in the epigenetic regulation of PTSD, providing a novel and unique perspective that will help to guide the development and application of new PTSD treatments.
创伤后应激障碍(PTSD)是一种相对常见但复杂的精神疾病,具有一系列不同的危险因素。典型症状包括对创伤性事件的重新体验或回避、认知障碍和高度警惕。虽然PTSD的确切发病机制尚不清楚,但许多研究表明表观遗传调控在其发展中起着关键作用。具体而言,大量研究表明,PTSD患者的组蛋白乙酰化和甲基化、DNA甲基化和非编码RNA水平发生了改变。此外,还发现天然产物通过调节表观遗传酶、长链非编码RNA (lncRNA)和miRNA的表达,实现PTSD的表观遗传调控,从而起到改善PTSD症状的作用。然而,到目前为止,还没有表观遗传调控相关的药物被用于治疗PTSD。此外,虽然能够从表观遗传上调节PTSD的天然产物受到越来越多的关注,但尚未有任何关于该主题的系统报告。本文综述了天然产物在PTSD表观遗传调控中的作用和机制,为指导PTSD新疗法的开发和应用提供了一个新的、独特的视角。

Objective

To investigate the therapeutic potential of octaarginine (R8)-modified essential oil from Fructus Alpiniae zerumbet (EOFAZ) lipid microspheres (EOFAZ@R8LM) for cardiovascular therapy.

Methods

EOFAZ@R8LM was developed by leveraging the volatilization of EOFAZ and integrating it with the oil phase of LM, followed by surface modification with cell-penetrating peptide R8 to target the site of vascular endothelial injury. The therapeutic effects of this formulation in alleviating lipopolysaccharide-induced vascular endothelial inflammation were evaluated by assessing mitochondrial membrane potential (MMP), intracellular reactive oxygen species (ROS) levels, as well as inflammatory factors interleukin-6 (IL-6) and interleukin-1β (IL-1β) levels.

Results

EOFAZ@R8LM effectively delivered EOFAZ to the site of injury and specifically targeted the mitochondria in vascular endothelial cells, thereby ameliorating mitochondrial dysfunction through regulation of MMP and reduction of intracellular ROS levels. Moreover, it attenuated the expression levels of IL-6 and IL-1β, exerting protective effects on the vascular endothelium.

Conclusion

Our findings highlight the significant therapeutic potential of EOFAZ@R8LM in cardiovascular therapy, providing valuable insights for developing novel dosage forms utilizing EOFAZ for effective treatment against cardiovascular diseases.

Objective

To investigate the therapeutic effects of Banxia Xiexin Decoction (BXD), a herbal medicine formula, on inflammation and the imbalance of the gut microbiota in a rat model of colorectal cancer (CRC) induced by azoxymethane (AOM) /dextran sulfate sodium (DSS).

Methods

A total of 75 male C57BL/6 mice were randomly divided into five groups: normal control group (NC), model group (MODEL), low-dose BXD treatment group (L-BXD), high-dose BXD treatment (H-BXD) group and MS treatment group (MS). BXD and MS were used in CRC mice at the doses of 3.915 g/kg, 15.66 g/kg, 0.6 g/kg for 3 weeks consecutively. Histopathological changes in the colon were observed using hematoxylin-eosin (HE) staining. The content of inflammatory factors in serum was detected by an enzyme-linked immunosorbent assay (ELISA), and the expression of mRNA and protein of genes related to immunity, apoptosis, inflammation, and inflammatory factors was evaluated. Changes in the intestinal flora of mouse fecal were determined based on high-throughput sequencing of the 16S rRNA microbial gene.

Results

Compared to the model group, the low-dose BXD and high-dose BXD groups decreased the number of colon tumors, reversed weight loss, and shortened colon length of mice. The pathological examination showed that BXD alleviated the malignancy of intestinal tumors. It also suppressed signal transducer and activator of transcription 3 (STAT3), matrix metalloproteinase-9 (MMP-9), and transforming growth factor beta 1 (TGF-β1) expression, while increasing the expression of the tight junction protein ZO-1 in colon tissues. Additionally, the levels of key pathway proteins involved in inflammation (phosphorylated-STAT3, Bcl-2, COX-2) and cell cycle regulatory molecules (c-Myc and PCNA) were reduced. According to 16S rRNA sequence analysis, BXD enhanced the relative abundance of potentially beneficial bacteria, while that of cancer-related bacteria decreased.

Conclusion

BXD plays a preventive role in developing colorectal cancer; its mechanisms are related to the inhibition of inflammation and tumor proliferation, as well as maintenance of intestinal homeostasis.
目的探讨半夏泻心汤(BXD)对偶氮氧甲烷(AOM) /葡聚糖硫酸钠(DSS)诱导的大鼠结直肠癌(CRC)模型炎症及肠道菌群失衡的治疗作用。方法将75只雄性C57BL/6小鼠随机分为正常对照组(NC)、模型组(model)、BXD低剂量治疗组(L-BXD)、BXD高剂量治疗组(H-BXD)和MS治疗组(MS)。BXD和MS分别以3.915 g/kg、15.66 g/kg、0.6 g/kg的剂量给药结直肠癌小鼠,连续3周。采用苏木精-伊红(HE)染色观察结肠组织病理学变化。采用酶联免疫吸附试验(ELISA)检测血清中炎症因子的含量,并检测免疫、细胞凋亡、炎症和炎症因子相关基因mRNA和蛋白的表达。基于16S rRNA微生物基因的高通量测序,确定了小鼠粪便肠道菌群的变化。结果与模型组比较,BXD低剂量组和高剂量组小鼠结肠肿瘤数量减少,体重减轻,结肠长度缩短。病理检查显示BXD能减轻肠道肿瘤的恶性。抑制信号传导和转录激活因子3 (STAT3)、基质金属蛋白酶-9 (MMP-9)、转化生长因子β1 (TGF-β1)的表达,增加结肠组织紧密连接蛋白ZO-1的表达。此外,参与炎症的关键途径蛋白(磷酸化的stat3, Bcl-2, COX-2)和细胞周期调节分子(c-Myc和PCNA)的水平降低。根据16S rRNA序列分析,BXD提高了潜在有益菌的相对丰度,而降低了癌症相关菌的相对丰度。结论bxd对大肠癌的发生具有预防作用;其机制与抑制炎症和肿瘤增殖以及维持肠道内稳态有关。

Objective

To study bioactive compounds from the endophytic fungus Penicillium sp. HJT-A-6 isolated from stem of Rhodiola tibetica, and evaluate its allelopathic activity.

Methods

The chemical constituents were isolated and purified by silica gel, Sephadex LH-20 column chromatography and semi-preparative HPLC. Their structures were elucidated by extensive spectroscopic analysis and electronic circular dichroism (ECD) calculations. In addition, the allelopathic activity of compound 1 was evaluated by measuring the seed germination rate of R. tibetica.

Results

Two new polyketides 4-hydroxy-3,6-dimethyl-2H-pyran-2-one (1) and penilactone E (2), together with six known compounds walterolactone A (3), 5-hydroxyhexan-4-olide (4), 3-methyl-2-penten-5-olide (5), chaetoquadrin F (6), (Z)-6-acetyl-3-(1,2-dihydroxypropylidene)-5-hydroxy-8-methylchroman-2-one (7) and 4-hydroxy-3-(4-hydroxyhexanoyl)-5-methylfuran-2(5H)-one (8) were isolated from Penicillium sp. HJT-A-6. Compound 1 showed moderate seed-germination-promoting activity at a concentration of 0.001 mg/mL while inhibiting the seed germination at concentrations of 0.1 and 0.01 mg/mL. Compared with the positive drug 6-benzyladenine (6-BA), compound 1 could extend the seed-germination period of R. tibetica (up to 11 d).

Conclusion

Two new compounds were isolated from R. tibetica endophytic fungus Penicillium sp. HJT-A-6. Compound 1 displayed plant hormone-like activity, which inhibited the seed germination of the host plant at high concentrations and promoted the seed germination of the host plant at low concentrations. The results not only enrich the chemical constituents of the endophytic fungi isolated from Rhodiola tibetica, but also provide a theoretical basis for understanding the interaction mechanism between Rhodiola tibetica endophytic fungi and the host plant.

Objective

Exploring the formation and aggregation of human islet amyloid polypeptide (hIAPP) (amylin) fibers is significant for promoting the prevention and treatment of type II diabetes mellitus (T2DM). Flavones in pomelo peel have visible biological activity in the anti-diabetes aspect. The present study aimed to investigate the effects of five flavones [naringin (NRG), narirutin (NRR), nobiletin (NOB), sinensetin (SIN), and neohesperidin (NHP)] in pomelo peel on peptide aggregation and explore its possible mechanisms. The cell viability of flavones against peptide aggregation was also evaluated.

Methods

The thioflavin T (ThT) assay and transmission electron microscopy (TEM) were used for evaluating the inhibition and disaggregation of flavones on peptide aggregation. The interaction mechanism was analyzed by endogenous fluorescence, molecular dynamics (MD) simulations, ultraviolet spectroscopy (UV) and isothermal titration calorimetry (ITC) experiments. The 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyl tetrazolium bromide (MTT) and immune assays were performed to characterize the cell viability of flavones against peptide aggregation.

Results

The five flavones showed a decrease in fluorescence intensity, fiber number and size under incubation with different molar ratios of hIAPP. The compounds can bind to the aromatic tyrosine (Tyr) residueTyr 37, resulting in the intrinsic fluorescence quenching of the peptides. Five flavones can form hydrogen bonds with hIAPP, which is likely to be based on their phenolic hydroxyl structure. They showed strong binding affinity with peptides. The reaction system of NRG and NRR observed an exothermic reaction, and the others were endothermic reactions. The absorption peaks of the compounds with hIAPP changed and showed hypochromic effects, indicating that there may be π-π stacking interaction. Flavones noticeably increased the cell viability in the presence of amyloid peptides and reduced the absorption intensity induced by peptide oligomers.

目的探讨人胰岛淀粉样多肽(hIAPP)(胰淀素)纤维的形成和聚集,对促进2型糖尿病(T2DM)的预防和治疗具有重要意义。柚皮中的黄酮在抗糖尿病方面具有明显的生物活性。本研究旨在研究柚皮中五种黄酮[柚皮苷(naringin, NRG)、柚皮素(narirutin, NRR)、柚皮素(NOB)、柚皮素(sinensetin, SIN)和新橙皮苷(nehesperidin, NHP)]对肽聚集的影响,并探讨其可能的机制。并对黄酮抗肽聚集的细胞活力进行了评价。方法采用硫黄素T (ThT)测定法和透射电镜(TEM)观察黄酮类化合物对多肽聚集的抑制和分解作用。通过内源荧光、分子动力学(MD)模拟、紫外光谱(UV)和等温滴定量热(ITC)实验分析了相互作用机理。采用3-[4,5-二甲基噻唑-2-基]-2,5-二苯基溴化四唑(MTT)和免疫实验表征黄酮抗肽聚集的细胞活力。结果在不同的hIAPP摩尔比下,5种黄酮类化合物的荧光强度、纤维数量和大小均有所降低。该化合物可与芳香酪氨酸(Tyr)残基ety37结合,导致多肽的固有荧光猝灭。五种黄酮类化合物可以与hIAPP形成氢键,这可能是基于它们的酚羟基结构。它们与多肽具有较强的结合亲和力。NRG和NRR的反应体系为放热反应,其余为吸热反应。掺入hIAPP的化合物的吸收峰发生了变化,并表现出异色效应,表明可能存在π-π堆积相互作用。在淀粉样肽存在的情况下,黄酮显著提高了细胞活力,降低了肽寡聚物诱导的吸收强度。结论柚皮中5种黄酮对淀粉样蛋白原纤维具有抑制和解聚作用,能显著保护细胞免受hIAPP的毒性作用,减少毒性低聚物的产生。

Objective

Myocardial inflammation during myocardial infarction (MI) could be inhibited by regulating arachidonic acid (AA) metabolism. Recent studies demonstrated that Sini Decoction (SND) was identified to be an effective prescription for treating heart failure (HF) caused by MI. But the anti-inflammatory mechanism of SND remained unclear. The work was designed to investigate the anti-inflammatory mechanism of SND through the AA metabolism pathway in vitro and in vivo experiments.

Methods

An inflammatory injury model of H9c2 cells was established by lipopolysaccharide (LPS)-stimulated macrophage-conditioned medium (CM). The MI model was built by the ligation of left anterior descending (LAD) branch of coronary artery in rat. Meanwhile, the rats were divided into five groups: sham group, MI group, MI + Celecoxib group, MI + low-dose SND group (SND-L) and MI + high-dose SND group (SND-H). Cardiac function, histopathological changes and serum cytokines were examined four weeks later. Western blot analysis was conducted to verify the key enzymes levels in the AA metabolic pathway, including phospholipase A2 (PLA2), cyclooxygenases (COXs) and lipoxygenases (LOXs).

Results

These in vivo results demonstrated that SND could improve the cardiac function and pathological changes of rats with MI, and regulate the key inflammatory molecules in the AA metabolism pathway, including sPLA2, COX-1, COX-2, 5-LOX and 15-LOX. In vitro, SND could decrease the release of pro-inflammatory cytokines including TNF-α and IL-6 and inhibit cell apoptosis in CM-induced H9c2 cells. Moreover, SND could protect H9c2 cells from the damage of CM by regulating nuclear factor kappa-B (NF-κB) signal pathway and the expression of COX-2.

Conclusion

SND may be a drug candidate for anti-inflammatory treatment during MI by regulating the multiple targets in the AA metabolism pathway.
目的通过调节花生四烯酸(AA)代谢抑制心肌梗死(MI)时的心肌炎症反应。近年来研究证实四逆汤是治疗心肌梗死所致心力衰竭的有效方药,但其抗炎机制尚不清楚。本工作旨在通过体外和体内实验探讨SND的抗炎机制。方法采用脂多糖(LPS)刺激的巨噬细胞条件培养基(CM)建立H9c2细胞炎症损伤模型。采用冠状动脉左前降支结扎法建立心肌梗死模型。同时将大鼠分为5组:假手术组、心肌梗死组、心肌梗死+塞来昔布组、心肌梗死+低剂量SND组(SND- l)和心肌梗死+高剂量SND组(SND- h)。4周后检测心功能、组织病理变化及血清细胞因子。Western blot分析验证了AA代谢途径中的关键酶水平,包括磷脂酶A2 (PLA2)、环氧化酶(cox)和脂氧化酶(LOXs)。结果体内实验结果表明,SND可改善心肌梗死大鼠的心功能和病理改变,调节AA代谢途径中的关键炎症分子sPLA2、COX-1、COX-2、5-LOX和15-LOX。在体外,SND可减少cm诱导的H9c2细胞中TNF-α、IL-6等促炎因子的释放,抑制细胞凋亡。SND通过调节核因子κ b (NF-κB)信号通路和COX-2的表达,保护H9c2细胞免受CM损伤。结论snd可能通过调节AA代谢途径中的多个靶点,成为心肌梗死抗炎治疗的候选药物。

Objective

Paridis Rhizoma (Chonglou in Chinese), a traditional Chinese herbal medicine, has been shown have strong anti-tumor effects. Paris saponin VII (PSVII), an active constituent isolated from Paridis Rhizoma, was demonstrated to significantly suppress the proliferation of BxPC-3 cells in our previous study. Here, we aimed to elucidate the anti-pancreatic ductal adenocarcinoma (PDAC) effect of PSVII and the underlying mechanism.

Methods

Cell viability was determined by CCK-8, colony formation, and cell migration assays. Cell apoptosis and reactive oxygen species (ROS) production were measured by flow cytometry with annexin V/propidine iodide (Annexin V/PI) and 2′,7′-dichlorodihydrofluorescein diacetate (DCFH-DA), respectively. Pyroptosis was evaluated by morphological features, Hoechst 33342/PI staining assay, and release of lactate dehydrogenase (LDH). JC-1 fluorescent dye was employed to measure mitochondrial membrane potential. Western blotting and reverse transcription-quantitative polymerase chain reaction (RT-qPCR) were used to determine the levels of proteins or mRNAs. The effect in vivo was assessed by a xenograft tumor model.

Results

PSVII inhibited the viability of PDAC cells (BxPC-3, PANC-1, and Capan-2 cells) and induced gasdermin E (GSDME) cleavage, as well as the simultaneous cleavage of Caspase-3 and poly (ADP-ribose) polymerase 1 (PARP). Knockdown of GSDME shifted PSVII-induced pyroptosis to apoptosis. Additionally, the effect of PSVII was significantly attenuated by Z-Asp(OMe)-Glu(OMe)-Val-Asp(OMe)-fluoromethylketone (Z-DEVD-FMK), on the induction of GSDME-dependent pyroptosis. PSVII also elevated intracellular ROS accumulation and stimulated Bax and Caspase-3/GSDME to conduct pyroptosis in PDAC cells. The ROS scavenger N-acetyl cysteine (NAC) suppressed the release of LDH and inhibited Caspase-9, Caspase-3, and GSDME cleavage in PDAC cells, ultimately reversing PSVII-induced pyroptosis. Furthermore, in a xenograft tumor model, PSVII markedly suppressed the growth of PDAC tumors and induced pyroptosis.

Conclusion

These results demonstrated that PSVII exerts therapeutic effects through Caspase-3/GSDME-dependent pyroptosis and may constitute a novel strategy for preventing chemotherapeutic resistance in patients with PDAC in the future.
目的重楼是一种具有较强抗肿瘤作用的中草药。巴黎皂苷VII (Paris saponin VII, PSVII)是一种从Paridis Rhizoma中分离得到的活性成分,我们在之前的研究中发现它能显著抑制BxPC-3细胞的增殖。本研究旨在阐明PSVII抗胰腺导管腺癌(PDAC)的作用及其机制。方法采用CCK-8法、菌落形成法和细胞迁移法测定细胞活力。用膜联蛋白V/碘化丙啶(annexin V/PI)和2′,7′-二氯二氢荧光素(DCFH-DA)分别流式细胞术检测细胞凋亡和活性氧(ROS)产生。通过形态学特征、Hoechst 33342/PI染色法和乳酸脱氢酶(LDH)的释放来评估焦亡。采用JC-1荧光染料测定线粒体膜电位。采用Western blotting和逆转录-定量聚合酶链反应(RT-qPCR)检测蛋白或mrna水平。通过异种移植肿瘤模型评估其在体内的效果。结果spsvii抑制PDAC细胞(BxPC-3、PANC-1和Capan-2细胞)的活性,诱导gasdermin E (GSDME)的裂解,以及Caspase-3和聚adp核糖聚合酶1 (PARP)的同步裂解。GSDME敲低将psvii诱导的焦亡转变为细胞凋亡。此外,Z-Asp(OMe)-Glu(OMe)-Val-Asp(OMe)-氟甲基酮(Z-DEVD-FMK)显著减弱PSVII对gsdme依赖性焦亡的诱导作用。PSVII还能提高PDAC细胞内ROS积累,刺激Bax和Caspase-3/GSDME导致PDAC细胞焦亡。活性氧清除剂n -乙酰半胱氨酸(NAC)抑制LDH的释放,抑制PDAC细胞中Caspase-9、Caspase-3和GSDME的切割,最终逆转psvi诱导的焦亡。此外,在异种移植肿瘤模型中,PSVII显著抑制PDAC肿瘤的生长并诱导焦亡。结论PSVII通过Caspase-3/ gsdme依赖性焦亡发挥治疗作用,可能成为未来预防PDAC患者化疗耐药的新策略。
