Exosomal microRNA-618 derived from mesenchymal stem cells attenuate the progression of hepatic fibrosis by targeting Smad4

Introduction Hepatic fibrosis (HF) is a pathological phenomenon produced in the process of long-term damage and repair in the liver [1,2]. During the formation of HF, hepatocytes are damaged by various factors, such as chronic liver disease, and excessive intake of alcohol, and secrete a variety of cytokines [3]. Subsequently,…

New bioinformatics method to analyze viral sgRNA

Single guide ribonucleic acid (sgRNA) molecules are produced by discontinuous transcription, in which viral RNA-dependant RNA polymerase pauses early negative-sense RNA synthesis and then jumps to the other end of the genome. The specifics of this process are still not fully understood. Since sgRNAs can play an important role in…

Pericentromeric noncoding RNA changes DNA binding of CTCF and inflammatory gene expression in senescence and cancer

Significance During the aging process, senescent cells secrete inflammatory factors, causing various age-related pathologies. Thus, controlling the senescence-associated secretory phenotype (SASP) can tremendously benefit human health. Although SASP seems to be induced by the alteration of chromosomal organization, its underlying mechanism remains unclear. Here, it has been revealed that noncoding…
