Alternative splicing is a crucial mechanism of gene regulation and this process can be dysregulated in cancer. In pituitary tumors (PitNETs), alteration in the serine/arginine-rich splicing factors (SRSFs) has been reported. Newly synthetized SRSFs are phosphorylated by serine-arginine protein kinase 1 (SRPK1) to facilitate their nuclear import. In response to extracellular stimuli SRPK1 may translocate to the nucleus as well to hyperphosphorylate SRSFs and favor their interac...

Non-functioning pituitary neuroendocrine tumors (NF-PitNETs) are still orphan of medical therapy. The drmgs approved for the other types of PitNETs, e.g. somatostatin analogues (SSA) with high affinity for somatostatin receptors (SSTs) type 2 (SST2) and 5 (SST5) are poorly efficacious in NF-PitNETs. Among SSTs, NF-PitNETs express high levels of SST3, a receptor that can mediate antiproliferative and apoptotic signaling. ITF2984 is a pan-SST ligand with high affinity for SST3, ...
