Since the RA/SARAH affinity is relatively low, whereas that of the SARAH heterodimer is in the nM range, we suggest that RASSF5 exerts its tumor suppressor action through competition with other Ras effectors for Ras effector binding site, as well as coincidentally its recruitment to the membrane to help MST activation.
In conclusion, despite the high therapeutic potential of TIs such as MST-312, the molecular outcomes of long-term exposure of tumors on these drugs have to be evaluated when considering their clinical application, especially for breast cancer treatment.
Moreover, t-SNE and MST-kNN clustering approaches based on 10,000 probes, associated with luminal tumour initiation and/or development, revealed the close connections between luminal A and B tumours, with no evidence of a clear boundary between them.
