Involvement of HIF-1 α-regulated miR-21, acting via the Akt/NF-κB pathway, in malignant transformation of HBE cells induced by cigarette smoke extract.
Involvement of HIF-1α-regulated miR-21, acting via the Akt/NF-κB pathway, in malignant transformation of HBE cells induced by cigarette smoke extract. Toxicol Lett. 2018 Feb 28;: Authors: Lu L, Xu H, Yang P, Xue J, Chen C, Sun Q, Yang Q, Lu J, Shi A, Liu Q Abstract Although the relationship between cigarette smoke and lung cancer has been widely studied, the molecular mechanism for cigarette smoke-induced lung cancer remains largely unclear. The present study investigated the roles of hypoxia-inducible factor (HIF)-1α and miR-21 in the malignant transformation of human bronchial epithelial (HBE) ce...

The IL-6/STAT3 pathway via miR-21 is involved in the neoplastic and metastatic properties of arsenite-transformed human keratinocytes.
Abstract Inflammation and microRNAs are involved in human skin cancer; however, their molecular mechanisms remain unclear. Further, a concern in skin cancer research is the identification of biomarkers for early diagnosis and accurate prognosis. To explore new biomarkers of chemical exposure in risk assessment of chemical carcinogenesis and arsenite-induced skin cancer, we investigated the roles of interleukin-6 (IL-6) regulation of microRNA-21 (miR-21), functioning via activation of signal transducers and activators of transcription 3 (STAT3), in neoplastic and metastatic properties of immortalized human keratino...
