Abstract:
There exists a general recognition of the fact that LXR-α, being a member of the nuclear receptor family, plays a crucial role in the biological process that connects inflammation, cholesterol homeostasis, and cellular decisions. In this context the present study was addressed to understand the role of LXR-α gene in the selective and specific reprogramming of cancer cells into a state of apoptosis leaving the normal cells unaffected. The results of this study revealed that LXR-α gene when activated in cancerous cells of diverse origin results in the regulation of genes coding for Bcl-2, AATF, and Par-4 in a fashion, forcing these cells to enter into the state of apoptosis leaving the normal cells unaffected. On the basis of this study we propose that in near future LXR-α agonist (Withaferin A) may definitely find its use in the therapeutic interventions directed towards the treatment of cancer.
