Histone lysine acylation is a major class of histone post-translational modifications involved in essential biological activities, such as transcriptional regulation, DNA-damage repair, and cell-cycle progression. Abnormal acylation is strongly associated with various diseases, such as cancer. Thus, histone acetyltransferases (HATs), the “writers” that catalyze histone acylation, are promising targets for cancer treatment. Rapid developments in structural biology and artificial intelligence have facilitated the development of drugs targeting HATs. To provide new ideas for exploring novel HAT modifiers with high efficiency and selectivity, this article reviews the relationships between acylation and diseases, illustrates HAT catalytic mechanisms through structural biology, and summarizes research progress in HAT modifiers.

Cuproptosis is a newly identified specific form of programmed cell death. Our study aimed to identify cuproptosis-related genes (CRGs) in patients with kidney renal clear cell carcinoma (KIRC) from the The Cancer Genome Atlas database and to evaluate CRG biological functions. Using lasso regression, we identified four KIRC prognosis-associated CRGs and constructed an associated prognostic risk signature. Kaplan-Meier curves showed that patients with high-risk scores had significantly lower survival times than patients with low-risk scores. Multivariate Cox analysis identified MTF1 and FDX1 as two independent overall survival CRGs. Moreover, qRT-PCR showed that MTF1 and FDX1 expression was downregulated in KIRC and knockdown of MTF1 and FDX1 significantly promoted KIRC cell proliferation and migration ability. In addition, the MTF1 level was positively correlated with immune cell infiltration and knockdown of MTF1 promoted tumor growth in vivo. We developed a signature of prognostic risk-associated CRGs that accurately predicted the prognostic status of KIRC patients. MTF1 and FDX1 were shown to be key CRGs. MTF1 acts as a tumor suppressor, and may be involved in the progression of KIRC by inhibiting proliferation and regulating immune cell infiltration.
铜增生是一种新发现的程序性细胞死亡的特殊形式。本研究旨在从the Cancer Genome Atlas数据库中鉴定肾透明细胞癌(KIRC)患者的铜肾病相关基因(cuprotoisisrelated genes, CRGs)，并评估CRG的生物学功能。使用套索回归，我们确定了四个与KIRC预后相关的crg，并构建了相关的预后风险特征。Kaplan-Meier曲线显示，高危评分患者的生存时间明显低于低危评分患者。多变量Cox分析发现MTF1和FDX1是两个独立的总生存CRGs。此外，qRT-PCR结果显示，KIRC中MTF1和FDX1的表达下调，MTF1和FDX1的下调显著促进了KIRC细胞的增殖和迁移能力。此外，MTF1水平与免疫细胞浸润呈正相关，体内MTF1敲低可促进肿瘤生长。我们开发了一种与预后风险相关的crg标记，可以准确预测KIRC患者的预后状况。MTF1和FDX1是关键的CRGs。MTF1作为肿瘤抑制因子，可能通过抑制增殖和调节免疫细胞浸润参与KIRC的进展。

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) caused a rapidly spreading outbreak of coronavirus disease 2019 (the COVID-19 pandemic). COVID-19 has severely affected healthcare systems worldwide, as well as the global economy, and has significantly increased morbidity and mortality rates. The majority of COVID-19-related deaths occurred in older individuals, primarily among those with concomitant diseases, including metabolic, respiratory, and cardiovascular diseases. Aging hallmarks, such as cellular senescence, chronic inflammation, and genomic instability, partially explain the increased disease severity at the molecular level with advancing age. Other multifactorial considerations, including healthcare facilities, socioeconomic status, and dissemination of epidemic information, may help control morbidity in the elderly population. While the World Health Organization declared an end to the emergency status of COVID-19 in May 2023, physical and emotional impairments may persist after recovery from the virus. Precautions should therefore be taken to prevent future pandemics, and suitable emphasis should be placed on addressing persistent COVID-19 and preventing future pandemics.

Owing to environmental and lifestyle changes in modern society, physical and mental stress is on the rise among the population in attempting to compensate for the changes. Stress, defined as a series of non-specific responses to abnormal internal and external stimuli, has long been recognized to increase susceptibility to various diseases, including neurodegenerative diseases (NDs). Herpes simplex virus type 1 (HSV-1), a neurotropic herpes virus, establishes latent infections in the trigeminal ganglia for the lifetime of the host. Upon reactivation, the latent HSV-1 enters the lytic cycle, which not only causes a substantial production of reactive oxygen species (ROS) in the neurons, but also induces glial cells to produce inflammatory mediators, eventually resulting in neuronal damage and occurrence of NDs. Remarkably, both physical and psychological stress are common stimuli leading to latent HSV-1 reactivation. Acyclovir is a classic antiviral drug for the treatment of HSV-1 infection and recurrence, but acyclovir cannot reverse neuronal damage caused by HSV-1 reactivation. Recent studies have shown that traditional Chinese medicine (TCM) has advantages in the treatment of NDs. In addition, TCM is thought to prevent latent HSV-1 reactivation and NDs, which may involve regulation of the neuro-endocrine-immune network, treatment of emotional disorders, and modulation of oxidative stress. Understanding the mechanism underlying stress-induced reactivation of latent HSV-1 and the potential consequences of NDs is needed. TCM may be a promising alternative therapy for related diseases.

Mass spectrometry imaging (MSI) has been shown to be a valuable tool through nearly every stage of the preclinical drug research and development (R&D) pipeline, and even to the early phase of clinical pharmaceutical evaluation. MSI can specifically resolve distributions of a parent drug and its metabolic products across dosed specimens without loss of spatial information, thus facilitating the direct observation of a drug’s pharmacokinetic processes, such as absorption, distribution, metabolism, and excretion. MSI can simultaneously visualize hundreds of phenotype molecules, including proteins, glycans, metabolites, and lipids, which have unique distribution patterns and biofunctions across different physiologic regions. This featured specificity in the chemical and physical spaces empowers MSI as an ideal analytical technique in exploring a drug’s pharmacodynamic properties, including in vitro/in vivo efficacy, safety, potential toxicity, and possible molecular mechanism. The application of MSI in pharmaceutical research has also been expanded from the conventional dosed tissue analysis to the front end of the preclinical drug R&D pipeline, such as investigating the structure-activity relationship, high-throughput in vitro screening, and ex vivo studies on single cells, organoids, or tumor spheroids. This review summarizes MSI application in pharmaceutical research accompanied by its technical and methodologic advances serving this central demand.

Traditional Chinese herbal (TCH) medicines have emerged as a prospective and affordable method to treat various diseases with a broad range of biological activity; however, traditional preparations, like decoctions, are often associated with low bioavailability, thus resulting in limited efficacy against cancer. The drawbacks of active TCH components, including instability, poor permeability, high hydrophilicity or hydrophobicity, undesirable pharmacokinetic profiles, and off-target toxicity, also exist. Most TCH medicines are thus limited to a clinical alternative for the treatment of chronic diseases. A liposomal delivery system is the most common class of FDA-approved nanomedicines, which has improved pharmacokinetics, enhanced targetability, and reduced side effects. Therefore, we anticipate that liposomal delivery technology will help concentrate drugs inside tumors, and fully release the therapeutic potential and reduce the side effects of TCH medicines. The review provides a brief overview of several representative TCH components and related liposome delivery strategies for enhanced cancer therapy. Current challenges associated with liposomal targeting of TCH medicines are also discussed for interested researchers.

Hydrogen sulfide (H2S) plays crucial roles in antioxidation, anti-inflammation, and cytoprotection. Despite substantial progress in the design and synthesis of activatable H2S donors, methods for high-precision detection and imaging of released H2S in living systems have been lacking. In this study, a biothiol-activated near-infrared (NIR) fluorescent H2S donor, PRO-ST, was developed for real-time visualization of H2S release. PRO-ST consists of a dicyanoisophorone-based NIR fluorescence moiety (TCOO), a biothiol-trigger moiety (4-isothiocyanate benzyl alcohol), and a sulfur-source group (thiophosgene). PRO-ST exhibits high NIR fluorescence enhancement (45-fold), outstanding H2S release efficiency (73%), controllable H2S release (60 min), and excellent cell compatibility. These distinctive features enable PRO-ST to be applied in visualizing H2S release in cells, zebrafish, and mice. Moreover, PRO-ST exhibits excellent performance in visualizing real-time anti-inflammation and wound healing enhancement in biological systems, as confirmed by in situ visualization of H2S release. Thus, PRO-ST provides a versatile and effective method to detect and visualize H2S release, elucidate the mechanisms underlying wound healing, or optimize interventional therapy.

Osteosarcoma is a primary malignant tumor of the skeleton with the morbidity of 2.5 in 1 million. The regularly on-set is in the epiphysis of the extremities with a high possibility of early metastasis, rapid progression, and poor prognosis. The survival rate of patients with metastatic or recurrent osteosarcoma remains low, and novel diagnostic and therapeutic methods are urgently needed. Exosomes are extracellular vesicles 30-150 nm in diameter secreted by various cells that are widely present in various body fluids. Exosomes are abundant in biologically active components such as proteins, nucleic acids, and lipids. Exosomes participate in numerous physiological and pathological processes via intercellular substance exchange and signaling. This review presents the novel findings of exosomes in osteosarcoma in diagnosis, prognosis, and therapeutic aspects.

Current anticancer treatments have many limitations to achieving high efficacy. Hence, novel strategies that broaden therapeutic prospects must urgently be developed. Ferroptosis is an iron-dependent form of non-apoptotic programmed cell death that is induced by cellular antioxidative system inhibition. Photodynamic therapy (PDT) uses photosensitizers to generate reactive oxygen species and aggravate oxidative stress in tumor cells. Combining ferroptosis with PDT cooperatively regulates intracellular redox homeostasis, thus increasing cancer cell susceptibility to oxidative stress and yielding synergistic anticancer effects. In this review, various strategies for combining ferroptosis with PDT are comprehensively summarized and discussed, including mono-PDT and PDT-induced ferroptosis, combining PDT with small-molecule ferroptosis inducers, and combining PDT with metal-ion-induced ferroptosis. Additionally, the possibility of combining ferroptosis and PDT with other anti-tumor therapies is discussed. Finally, the prospects and challenges of combining ferroptosis with PDT in clinical cancer treatment are addressed. With increased understanding of the superiority of combination PDT with ferroptosis for cancer treatment, we hope that drug delivery systems based on this strategy will be further developed to increase anticancer efficiency and achieve successful clinical translation.
