While mesothelin regulates cell proliferation and invasiveness, the mechanisms for the gene’s overexpression in malignant tumors have nonetheless to be clearly explained. The study printed in PLOS One is that the latest to analyze miR-21 as a possible regulator of mesothelin, however it's one in every of few to analysis the microRNA’s role within the formation of serous membrane carcinoma. “Although it's been extensively studied in cancer, miR-21-5p has been poorly investigated in MPM,” lead author Chiara DE Santi wrote within the study. “Here, miR-21-5p seems to act as a growth suppressor [microRNA] since it negatively regulated Associate in Nursing gene [mesothelin], and may|this might} be explained considering that [microRNAs] could play completely different roles looking on the pattern of their target mRNAs expressed therein specific cancer sort or tissue.”
