Unconventional Protein Secretion (UPS) in Cancer

Blog summary of an editorial perspective published in Oncotarget on entitled, “Leakage? or Secretion? unconventional protein secretion in cancer.” ________________________________________ Conventional protein secretion is fairly well understood in this day and age. Proteins that are secreted through the classical, secretory vesicle-related pathway contain a signal peptide that guides them to the endoplasmic reticulum (ER), where they are further processed and transported to the Golgi apparatus. From there, the Golgi apparatus modifies, sorts and packages proteins for transport to their final destinations within the cell or for secretion outside of the cell. However, in recent years, it has become clear that not all secreted proteins follow this conventional pathway. Instead, some proteins are secreted through unconventional pathways that do not require a signal peptide or the involvement of the ER or Golgi apparatus. In a recent editorial perspective published in Oncotarget on February 20, 2023, “Leakage? or Secretion? unconventional protein secretion in cancer,” researchers Kohji Yamada and Kiyotsugu Yoshida from The Jikei University School of Medicine in Tokyo, Japan, discuss unconventional protein secretion (UPS) and its significance in the progression of cancer. “In contrast, the secretion of proteins that do not code for signal peptides may occur via two or more mechanisms, often collectively referred to as unconventional protein secretion (UPS).” Full blog - https://www.oncotarget.org/2023/03/16/unconventional-protein-secretion-ups-in-cancer/ DOI - https://doi.org/10.18632/oncotarget.28368 (PDF Download) Correspondence to - Kohji Yamada - kyamada@jikei.ac.jp, and Kiyotsugu Yoshida - kyoshida@jikei.ac.jp Sign up for free Altmetric alerts about this article - https://oncotarget.altmetric.com/details/email_updates?id=10.18632%2Foncotarget.28368 Subscribe for free publication alerts from Oncotarget - https://www.oncotarget.com/subscribe/ Keywords - unconventional protein secretion, cancer, endoplasmic reticulum About Oncotarget Oncotarget is a primarily oncology-focused, peer-reviewed, open access journal.
