As an evolutionarily conserved metabolic process, autophagy is involved in the process of atherosclerosis (AS). MicroRNA-155 (miR-155), a multifunctional miRNA, plays an important role in many physiological and pathological conditions, including AS and autophagy. However, the effect of miR-155 on the regulation of autophagy in endothelial cells has not been reported to date. Therefore, the obje...
it has been well documented that preeclampsia (pe) has a common etiological background, but little is known about its linkage at the molecular level.non- coding rnas are critical posttranscriptional regulators ofgene expression. this study was performed to determine whether peis associated with alterations in placental non-codingrnas expression. microrna(mir)-155-5p and long non-coding rna (ln...
Chronic lymphocytic leukemia (CLL) is the most common leukemia of adults in Western countries. There are approximately 19 000 new cases diagnosed in the United States in 2016 (https://seer. cancer.gov/statfacts/html/clyl.html). MicroRNAs (miRs) have been implicated as one of the key contributors in the pathogenesis of CLL. One of these miRNAs is miR-155, which is probably the bestcharacterized ...
Multiple studies have established that microRNAs (miRNAs) are involved in the initiation and progression of cancer. Notably, miR-155 is one of the most overexpressed miRNAs in several solid and hematological malignancies. Ectopic miR-155 expression in mice B cells (Eμ-miR-155 transgenic mice) has been shown to induce pre-B-cell proliferation followed by high-grade lymphoma/leukemia. Loss of miR...
MicroRNA-155 (miR-155) regulates antibody responses and subsequent B-cell effector functions to exogenous antigens. However, the role of miR-155 in systemic autoimmunity is not known. Using the death receptor deficient (Fas(lpr)) lupus-prone mouse, we show here that ablation of miR-155 reduced autoantibody responses accompanied by a decrease in serum IgG but not IgM anti-dsDNA antibodies and a ...
The molecular mechanisms of intervertebral disc degeneration (IDD) remain elusive. We found that miR-155 is down-regulated in degenerative nucleus pulposus (NP), and more severe degeneration is correlated with higher matrix metallopeptidase 16 (MMP-16) expression. MMP-16 also degraded matrix aggrecan. Here, we addressed the in vivo miR-155-mediated pathological impact on IDD using a classic pun...
Acupuncture has been used to treat chronic atrophic gastritis (CAG) in traditional Chinese medicine (TCM) for centuries. In this study, we evaluated the effect of acupuncture at Zusanli (ST36), Zhongwan (CV12), and Pishu (BL20) acupoints on weight changes of rats, histological changes of gastric glands, and expressions changes of nuclear factor-kappa B (NF-κB) p65, microRNA- (miR-) 155, miR-21,...
Previously, we identified a microRNA (miRNA) signature for endothelial cells (ECs) subjected to unidirectional shear stress (USS). MiR-155, a multifunctional miRNA that has been implicated in atherosclerosis, was among the shear stress-responsive miRNAs. Here, we examined the role of miR-155 in modulating EC phenotype and function. In vitro, increased miR-155 levels in human ECs induced changes...
Invariant natural killer T cells (iNKT cells) are CD1d-restricted, lipid antigen-reactive T lymphocytes with immunoregulatory functions. iNKT cell development in the thymus proceeds through subsequent stages, defined by the expression of CD44 and NK1.1, and is dictated by a unique gene expression program, including microRNAs. Here, we investigated whether miR-155, a microRNA involved in differe...
Colorectal carcinoma (CRC) is a malignant solid tumor arising from the large intestine and is associated with an increasing incidence and poor prognosis. Further understanding of the molecular mechanisms underlying CRC may contribute to the development of novel effective therapeutic strategies. MicroRNAs (miRs), including miR‑155, have been reported to be associated with the etiology and biolog...
