HDACs in the Brain: From Chromatin Remodeling to Neurodegenerative Disease.

Histone deacetylases (HDACs) are key epigenetic regulators that influence chromatin remodeling, gene expression, and cellular plasticity in the central nervous system (CNS). This review provides a comprehensive overview of the classification and functional diversity of HDACs, with particular emphasis on their roles in neural progenitor cells, mature neurons, and glial populations. In neural stem and progenitor cells, HDACs modulate neurogenesis, fate specification, and lineage commitment. In differentiated neurons, HDACs govern synaptic plasticity, memory formation, and survival. In glial cell

Starvation-induced long non-coding RNAs are significant for prognosis evaluation of bladder cancer.

BackgroundStarving intratumoral microenvironment prominently alters genic profiles including long non-coding RNAs (lncRNAs), which further regulate bladder cancer (BCa) malignant biological properties, such as invasion and migration.MethodsTranscriptome RNA-sequencing data of 414 BCa tumor tissues and 19 normal tissues were obtained from TCGA database and paired samples of 132 BCa patients. A chain of in vitro validations such as qPCR, migration and invasion assays were performed to reveal the clinical relevance of AC011472.4 and AL157895.1.ResultsA total of 11 lncRNAs were identified as starv

Zoledronic acid infusion for prevention and treatment of osteoporosis.

Osteoporotic fractures are associated with significant morbidity, reduced quality of life, increased mortality, and high health care costs. Bisphosphonates are standard therapy for treatment of osteoporosis. However, patient compliance and persistence with oral weekly or monthly bisphosphonate therapy are suboptimal and may lead to reduced effectiveness. Zoledronic acid (ZOL) is an intravenous bisphosphonate that is given once yearly for the treatment of osteoporosis via a medically supervised 15-minute infusion. This ensures compliance for a full 12 months. In clinical trials, an annual infus

Heterogeneity in precision oncology.

Precision oncology is a rapidly evolving concept that holds great promise in cancer treatment. However, a cancer complexity attributed to genomic and acquired tumour heterogeneity limits treatment effectiveness and increases toxicity. These limitations refer to both systemic therapies and radiotherapy, which are two mainstays of non-invasive cancer treatment. By understanding cancer heterogeneity and utilising advanced tools to personalise treatment strategies, precision oncology has the potential to revolutionise cancer care. In this article, we review the current status of precision oncology

Ready for Repair? Gene Editing Enters the Clinic for the Treatment of Human Disease.

We present an overview of clinical trials involving gene editing using clustered interspaced short palindromic repeats (CRISPR)-CRISPR-associated protein 9 (Cas9), transcription activator-like effector nucleases (TALENs), or zinc finger nucleases (ZFNs) and discuss the underlying mechanisms. In cancer immunotherapy, gene editing is applied ex vivo in T cells, transgenic T cell receptor (tTCR)-T cells, or chimeric antigen receptor (CAR)-T cells to improve adoptive cell therapy for multiple cancer types. This involves knockouts of immune checkpoint regulators such as PD-1, components of the endo

Current advances of CRISPR-Cas technology in cell therapy.

CRISPR-Cas is a versatile genome editing technology that has been broadly applied in both basic research and translation medicine. Ever since its discovery, the bacterial derived endonucleases have been engineered to a collection of robust genome-editing tools for introducing frameshift mutations or base conversions at site-specific loci. Since the initiation of first-in-human trial in 2016, CRISPR-Cas has been tested in 57 cell therapy trials, 38 of which focusing on engineered CAR-T cells and TCR-T cells for cancer malignancies, 15 trials of engineered hematopoietic stem cells treating hemog

Oncogenic Roles and Inhibitors of DNMT1, DNMT3A, and DNMT3B in Acute Myeloid Leukaemia.

Epigenetic alteration has been proposed to give rise to numerous classic hallmarks of cancer. Impaired DNA methylation plays a central role in the onset and progression of several types of malignancies, and DNA methylation is mediated by DNA methyltransferases (DNMTs) consisting of DNMT1, DNMT3A, and DNMT3B. DNMTs are frequently implicated in the pathogenesis and aggressiveness of acute myeloid leukaemia (AML) patients. In this review, we describe and discuss the oncogenic roles of DNMT1, DNMT3A, and DNMT3B in AML. The clinical response predictive roles of DNMTs in clinical trials utilising hy

Hypoxia-driven angiogenesis and metabolic reprogramming in vascular tumors.

Hypoxia is a hallmark of the tumor microenvironment (TME), and it plays a crucial role in the occurrence and progression in vascular tumors. Under hypoxic conditions, hypoxia-inducible factor 1-alpha (HIF-1α) is stabilized, inducing changes in the expression of various target genes involved in angiogenesis, metabolism, and cell survival. This includes the upregulation of pro-angiogenic factors like VEGF, which promotes the formation of dysfunctional blood vessels, contributing to the worsening of the hypoxic microenvironment. At the same time, hypoxia induces a metabolic shift toward glycolysi

Thiostrepton Suppresses the Progression of Rhabdomyosarcoma by Inhibiting the PI3K-AKT Signaling Pathway.

Rhabdomyosarcoma (RMS), the most common pediatric soft tissue sarcoma with 5-year survival below 30% in high-risk/metastatic cases, was investigated through integrated bioinformatics analysis (identifying 269 conserved differentially expressed genes in GEO datasets GSE28511/GSE141690) and experimentally validated thiostrepton (TST), a ribosomal-targeting antibiotic, as a potent therapeutic candidate via Connectivity Map analysis (p p AKT, JAK, CDKs). This was confirmed by PI3K activator 740 Y-P rescue experiments, which partially reversed the effects of TST (p < 0.05). These findings establish

Osteosarcoma of the appendicular skeleton in dogs: consensus and guidelines.

Osteosarcoma (OSA) in dogs poses a clinical challenge to veterinary practitioners across the globe. As knowledge evolves, so too do clinical practices. However, there remain uncertainties and controversies. There is value for the veterinary community at large in the generation of a contemporary wide-ranging guideline document. The aim of this project was therefore to assimilate the available published knowledge into a single accessible referenced resource and to provide expert clinical guidance to support professional colleagues as they navigate current OSA challenges and controversies. Primar

Advances in real-world research on fertility preservation in men with malignant tumours.

Malignant tumours have become one of the diseases that seriously threaten human health, and their incidence is increasing year by year. Worldwide, malignant tumours have become one of the most common causes of death in men. With the continuous progress of comprehensive oncological treatment, the cure rate and the survival rate of malignant tumours have been increasing, and the survival cycle has been prolonged, so the issue of fertility preservation in male malignant tumour patients has received widespread attention. In this review, researchers will discuss the real-world research progress rel

Targeting endoplasmic reticulum stress-induced lymphatic dysfunction for mitigating bisphosphonate-related osteonecrosis.

BACKGROUND: Bisphosphonates (BPs) are the first-line treatment to stop bone resorption in diseases, including osteoporosis, Paget's disease, multiple myeloma and bone metastases of cancer. However, BPs-related osteonecrosis of the jaw (BRONJ), characterized by local inflammation and jawbone necrosis, is a severe intractable complication. The cumulative inflammatory burden often accompanies impaired lymphatic drainage, but its specific impact on BRONJ and the underlying mechanisms remain unclear. METHODS: The mouse BRONJ model was established to assess the integrity and drainage function of ly

Sohlh2 inhibited the angiogenesis of hepatocellular carcinoma through the HIF-1α/VEGFA pathway.

PurposeTo investigate the role of Sohlh2 in hepatocellular carcinoma (HCC) and its potential mechanisms.MethodsThis study focused on Hep3B and HepG2 cells and employed lentiviral transfection to create Sohlh2 overexpression and knockdown models. Through CCK8, flow cytometry, angiogenesis and immunofluorescence experiments, the effects of Sohlh2 on tumor cell proliferation, cell cycle progression, apoptosis, and angiogenesis were investigated. Additionally, its regulatory role in the HIF-1α/VEGFA pathway was explored. The experiments were repeated after introducing the Sohlh2 agonist CoCl2 and
