Recently, bone marrow has been considered as playing a critical role in the generation of both metastasis and recurrent disease. The accumulation of a single microRNA in the bone marrow has the potential to regulate the translation of multiple genes in cancer metastasis and may therefore serve as a prognostic marker for cancer recurrence. MicroRNA microarray analysis was performed to compare mi...

This study investigated the mechanism of microRNA-21 in regulating IL-6 inflammatory response and cell autophagy in intervertebral disc degeneration. A total of 10 patients with lumbar disc herniation accompanied by nerve root pain (observation group) and 10 patients with lumbar burst fractures (control group) were selected. The nucleus pulposus tissues of the lesion were obtained during operat...

Objective Post-percutaneous coronary intervention (PCI) myocardial injury is related to the CD4+ T lymphocyte-mediated inflammatory response. microRNA-21 expression is associated with CD4+ T lymphocyte activation. The pre-PCI use of trimetazidine prevents periprocedural myocardial injury and reduces inflammatory cytokine levels. This study aimed to assess the effects of trimetazidine on peripro...

MicroRNA-21 (miR-21) is an oncomiR and significantly upregulated in a wide range of cancers. It is strongly involved in apoptosis and oncogenesis, since most of its reported targets are tumor suppressors. Recently, miR-21 was found to be correlated with the pathogenesis of autoimmune diseases and may play an essential role in regulating autoimmune responses. In particular, miR-21 promotes Th17 ...

In response to appropriate stimuli in their microenvironment, naïve CD4 + T cells differentiate into one of several T helper cell lineages, such as Th1, Th2, Th17, and Treg cells, as defined by their transcription factor expression, cytokine secretion, and effector functions. Although T helper subsets are known to be regulated by specific transcription factors and cytokines, the molecular basis...

BACKGROUND microRNA (miRNA) expression profiles are being intensively investigated for their involvement in carcinogenesis. We evaluated the prognostic value of mature microRNA-21 (miR-21) and mature microRNA-205 (miR-205) overexpression in non-small cell lung cancer (NSCLC). PATIENTS AND METHODS We studied 48 pairs of NSCLC fresh frozen tissue specimens collected at time of surgery and befor...
