AI Article Synopsis
- RPSA is a ribosomal protein that was identified as a target of hydrogen peroxide (H2O2) in HeLa cells.
- Researchers investigated the localization of wild-type RPSA and a mutant form (with cysteine substitutions) in response to oxidative stress and antioxidant treatment.
- The study involved various methods like immunofluorescence and Western blotting to analyze RPSA's behavior and expression in different cellular conditions.
Article Abstract
Ribosomal Protein SA (RPSA), a component of the 40S ribosomal subunit, was identified as a H2O2 target in HeLa cells [1]. In order to analyze the intracellular localization of RPSA in different redox states we overexpressed wild-type RPSA (RPSAwt) or RPSA containing two cysteine to serine residue substitutions at positions 148 and 163 (RPSAmut) in HeLa cells. The transfected cells were exposed to H2O2 or N-acetylcysteine (NAC) and RPSA subcellular localization was assessed by immunofluorescence in permeabilized cells. In addition, co-immunofluorescence for RPSA and Ribosomal Protein S6 (RPS6) was performed in cells overexpressing RPSAwt or RPSAmut. Finally, the ribosomal expression of endogenous RPSA in the presence or absence of H2O2 was analyzed by Western blot. The data presented in this work is related to the research article entitled "Hydrogen peroxide regulates cell adhesion through the redox sensor RPSA" [1].
