A bioenergetic conception of insulin-independent diabetes mellitus (IIDM) is put forward. Molecular mechanisms of carbohydrate and fat metabolism are discussed which result in a vicious regulatory cycle to provoke a transition to stable pathology. Previously unknown role of human saliva in oral cavity in this regulatory cycle is revealed. New diagnostic tests are developed on the basis of the conception on IIDM pathogenesis. The results of clinical trials are presented which have been obtained during population screening.

N4-acetylcytidine (ac4C) modification is a crucial RNA modification widely present in eukaryotic RNA. Previous studies have demonstrated that ac4C plays a pivotal role in viral infections. Despite numerous studies highlighting the strong correlation between ac4C modification and cancer progression, its detailed roles and molecular mechanisms in normal physiological processes and cancer progression remain incompletely understood.

Massively Parallel Reporter Assays (MPRAs) have the potential to dramatically accelerate our genomic annotations by making it possible to measure the gene expression levels driven by thousands of mutational variants of a regulatory region. However, the interpretation of such data often assumes that each base pair in a regulatory sequence contributes independently to gene expression.

The proliferation of CAR-T cells was hindered and cannot play its killing function well in solid tumors. And yet the regulatory mechanism of CAR-T cell proliferation is not fully understood. Here, we showed that recombinant expression of CD19CAR in T cells significantly increased the basal activation level of CAR-T cells and LCK activation.

Background: Pancreatic adenocarcinoma (PAAD) is a common malignancy with a very low survival rate. More and more studies have shown that SPTAN1 may be involved in the development and progression of a variety of tumors, including rectal cancer, Pancreatic adenocarcinoma, etc., and may affect their prognosis.

The mechanism of Hespintor (a protein of serpin family) inhibitory action on the growth of inoculated hepatocellular carcinoma was studied in a model of human hepatoma in nude mice by using on long-noncoding RNA (lncRNA) sequencing. Two days after tumor transplantation, Hespintor or normal saline was injected into the caudal vein at a dose of 15 μg/kg (2 times a week over 4 weeks). The tumors were isolated in 4 weeks after subcutaneous injection of human hepatoma MHCC97-H cells.
