The Role of mA Modifications in B-Cell Development and B-Cell-Related Diseases.

B cells are a class of professional antigen-presenting cells that produce antibodies to mediate humoral immune response and participate in immune regulation. mA modification is the most common RNA modification in mRNA; it involves almost all aspects of RNA metabolism and can affect RNA splicing, translation, stability, etc. This review focuses on the B-cell maturation process as well as the role of three mA modification-related regulators-writer, eraser, and reader-in B-cell development and B-cell-related diseases.

Relationship between Tumor Infiltrating Immune Cells and Tumor Metastasis and Its Prognostic Value in Cancer.

Tumor metastasis is an important reason for the difficulty of tumor treatment. Besides the tumor cells themselves, the tumor microenvironment plays an important role in the process of tumor metastasis. Tumor infiltrating immune cells (TIICs) are one of the main components of TME and plays an important role in every link of tumor metastasis.

The Role of RNA Modification in HIV-1 Infection.

RNA plays an important role in biology, and more than 170 RNA modifications have been identified so far. Post-transcriptional modification of RNA in cells plays a crucial role in the regulation of its stability, transport, processing, and gene expression. So far, the research on RNA modification and the exact role of its enzymes is becoming more and more comprehensive.

Clinical efficacy of acetylcysteine combined with tetrandrine tablets on patients with silicosis and its effect on exercise tolerance and pulmonary function.

Clinical efficacy of acetylcysteine combined with tetrandrine tablets in the treatment of silicosis was investigated to observe the exercise tolerance and pulmonary function of the patients. The clinical data of 248 cases of silicosis patients treated in Branch of Tai'an City Central Hospital were retrospectively analyzed in this study, including 116 cases with conventional therapy (control group), and 132 cases treated with acetylcysteine and tetrandrine tablets on the basis of conventional therapy (observation group). The chest tightness, chest pain, cough and sputum production were evaluated by the St.
