Research Abstract |
In an acidic environment, myeloma cells sense an acid and activate survival pathways via PI3K-Akt. The activation and survival of the acid-sensitive myeloma cells to enhance the expression of the pH sensor their further the vicious circle enhancing signal is formed has been suggested. Moreover, nuclear translocation of the transcription factor Sp1 in myeloma cells was promoted expression of HDAC and suppressed gene expression of apoptosis-inducing factor DR4 in an acid environment. HDAC inhibitors were allowed to recover for the suppression of the expression of DR4. Therefore, PI3K-Akt inhibitors, and the combination of HDAC inhibitors and DR4 agonist antibody were considered a candidate for therapeutic agents to overcome drug resistance of myeloma cells in an acid environment.
