Roles and application of exosomes in the development, diagnosis and treatment of gastric cancer.

As important messengers of intercellular communication, exosomes can regulate local and distant cellular communication by transporting specific exosomal contents and can also promote or suppress the development and progression of gastric cancer (GC) by regulating the growth and proliferation of tumor cells, the tumor-related immune response and tumor angiogenesis. Exosomes transport bioactive molecules including DNA, proteins, and RNA (coding and noncoding) from donor cells to recipient cells, causing reprogramming of the target cells. In this review, we will describe how exosomes regulate the cellular immune response, tumor angiogenesis, proliferation and metastasis of GC cells, and the role and mechanism of exosome-based therapy in human cancer.

Mechanisms and applications of ferroptosis-associated regulators in cancer therapy and drug resistance.

Iron is an essential element for almost all living things. Both iron excess and iron deficiency can damage the body's health, but the body has developed complex mechanisms to regulate iron balance. The imbalance of iron homeostasis and lipid peroxidation are important features of ferroptosis.

Improving therapeutic resistance: beginning with targeting the tumor microenvironment.

Cancer is a serious threat to human health and life. The tumor microenvironment (TME) not only plays a key role in the occurrence, development and metastasis of cancer, but also has a profound impact on treatment resistance. To improve and solve this problem, an increasing number of strategies targeting the TME have been proposed, and great progress has been made in recent years.

Prevalence of dysphagia in multiple sclerosis: a systematic review and meta-analysis.

Although dysphagia was recognized as a clinical finding in multiple sclerosis (MS) as early as 1877, it has not received enough attention yet. With the progress of diagnostic method for dysphagia, there has been a rapid development in estimating the prevalence of deglutition disorder in MS. In this review, we aimed to conduct a systematic review and meta-analysis of published literature to establish the prevalence of dysphagia in multiple sclerosis.

A novel antioxidant isobenzofuranone derivative from fungus Cephalosporium sp.AL031.

Bioassay-guided fractionation of metabolites from the fungus Cephalosporium sp.AL031 isolated from Sinarundinaria nitida led to the discovery of a new isobenzofuranone derivative, 4,6-dihydroxy-5-methoxy-7-methylphthalide (1), together with three known compounds: 4,5,6-trihydroxy-7-methyl-1,3-dihydroisobenzofuran (2), 4,6-dihydroxy-5-methoxy-7-methyl-1,3-dihydroisobenzofuran (3) and 4,5,6-trihydroxy-7-methylphthalide (4).
