New insights into prostate Cancer from the renin-angiotensin-aldosterone system.

Prostate cancer is among the most common malignancies found in men, with multifactorial changes occurring altogether to disrupt the pathophysiology of this gland. The Renin-Angiotensin-Aldosterone System (RAAS) is an extensively studied pathway that has newly attributed fundamental roles in cancer biology that impact cell growth, migration, metastasis, and death. These processes are significantly influenced by various components of the RAAS, including prorenin, AT1R, AT2R, and Ang 1-7/Mas receptors.

Cancer Cachexia and breast cancer stem cell signalling - A crosstalk of signalling molecules.

Cancer Cachexia is a condition characterized by the involuntary loss of lean body mass, a negative protein and energy balance, and systemic inflammation. This syndrome profoundly impacts the patient's quality of life and is linked to poor chemotherapy response and reduced survival. Despite multiple mechanisms being implicated in its development, and various cytokines believed to contribute to the persistent catabolic state, cachexia is still not fully recognized and is often left untreated.
