In a mouse model of neurofibromatosis type 1, the purinergic receptor P2RY14 is a key regulator of Schwann cell precursor self-renewal and proliferation, of neurofibroma tumor initiation and of mouse survival.
Pre-neoplastic cells in the brain release SDF1, which mediates an immediate infiltration of macrophages that differentiate into microglia-like cells and promote proliferation of pre-neoplastic cells.

Substitutions in general translation initiation factor eIF1A found as recurring somatic mutations in uveal melanoma destabilize the closed conformation of the preinitiation complex at the start codon and increase discrimination against suboptimal initiation codons genome-wide.
