|dc.description.abstract||an evolutionarily conserved RNA-binding protein has pivotal roles in cancers as aberrant expression of LIN28A is related to metastasis and poor prognosis. Till now, limited data is available regarding the post-translationalregulatory mechanisms involved in LIN28A protein stabilization and cancer progression. Herein, I report that LIN28A protein undergoes ubiquitination which is reversed by Ubiquitin-specific protease 28 (USP28). This research also demonstrates the consequential functional effects of USP28-mediated LIN28A protein stability on tumor progression. Overall, this research emphasizes the role of DUBs in contributing to effective cancer therapeutics. Reactive oxygen species (ROS) generation being pivotal for multiple cell signaling processes involved in proliferation and apoptosis is tightly regulated to check deleterious oxidizing effects causing carcinogenesis. NADPH oxidases catalyze cellular ROS generation via NOX-related proteins. Herein, I report the role of CYLD in regulating NOXO1 protein and subsequent ROS generation and cancer. This study suggests a novel therapeutic approach of targeting NOXO1 and ROS generation by CYLD enzyme.||-|
