BECN1 and pituitary tumor: A study investigated macroautophagy in pituitary neuropathology with regards to Beclin1 and Microtubule-associated protein 1 light chain 3 (LC3) proteins [53], revealing that 60% of functioning pituitary tumors exhibited signs of macroautophagy, with higher Beclin1 and LC3 expression levels in macro-pituitary tumors compared to micro-pituitary tumors.
