Static and kinetic studies by fluorometry on the interaction between gluconolactone and glucoamylase from Rh. niveus.

abstract：:The cellular Src (c-Src) tyrosine kinase is upregulated and believed to play a pivotal role in various human cancers. However, the molecular mechanism underlying c-Src-mediated tumour progression remains elusive. Recent studies have revealed that several microRNAs (miRNAs) function as tumour suppressors by regulating ...
