Decreased miR-497-5p Suppresses IL-6 Induced Atrophy in Muscle Cells.

Interleukin-6 (IL-6) is a pro-inflammatory cytokine associated with skeletal muscle wasting in cancer cachexia. The control of gene expression by microRNAs (miRNAs) in muscle wasting involves the regulation of thousands of target transcripts. However, the miRNA-target networks associated with IL6-induced muscle atrophy remain to be characterized. Here, we show that IL-6 promotes the atrophy of C2C12 myotubes and changes the expression of 20 miRNAs (5 up-regulated and 15 down-regulated). Gene Ontology analysis of predicted miRNAs targets revealed post-transcriptional regulation of genes involve

Exosomes-loaded with traditional Chinese medicine constituents: a novel therapeutic avenue for aplastic anemia.

Aplastic anemia (AA) is a life-threatening blood disorder characterized by bone marrow failure and pancytopenia. Treatments such as immunosuppressive therapy (IST) and allogeneic hematopoietic stem cell transplantation (allo-HSCT) have limitations, including poor long-term remission and donor shortages. Exosomes, nanosized extracellular vesicles, are promising drug delivery systems (DDS) due to their biocompatibility, targeted delivery, and capacity to penetrate biological barriers. Traditional Chinese medicine (TCM) regulates hematopoiesis and immunity but faces challenges with delivery. This

Endoplasmic reticulum stress in disease pathogenesis: its implications for therapy.

Endoplasmic reticulum (ER) stress is a key cellular mechanism that is important in the development of many diseases, including cancer. Since the discovery of the unfolded protein response (UPR), research has greatly improved our understanding of how ER stress affects cellular functions, especially protein folding and adaptation to stress. The UPR consists of three main branches: IRE1, ATF6, and PERK, each of which is crucial for regulating stress responses, protein homeostasis, and apoptosis. These pathways normally help cells handle stress effectively; however, excessive or prolonged activati

Antioxidants in brain tumors: current therapeutic significance and future prospects.

Brain cancer is regarded among the deadliest forms of cancer worldwide. The distinct tumor microenvironment and inherent characteristics of brain tumor cells virtually render them resistant to the majority of conventional and advanced therapies. Oxidative stress (OS) is a key disruptor of normal brain homeostasis and is involved in carcinogenesis of different forms of brain cancers. Thus, antioxidants may inhibit tumorigenesis by preventing OS induced by various oncogenic factors. Antioxidants are hypothesized to inhibit cancer initiation by endorsing DNA repair and suppressing cancer progress
