PRIMA‑1 induces autophagy in colorectal cancer cells through upregulation of the mTOR/AMPK‑ULK1‑Vps34 signaling cascade.

Oncol Rep 2021 May 13;45(5). Epub 2021 Apr 13.

Department of Gastroenterology, The Affiliated Suzhou Hospital of Nanjing Medical University, Suzhou, Jiangsu 215001, P.R. China.

p53‑reactivation and induction of massive apoptosis‑1, APR‑017 methylated (PRIMA‑1; APR246) targets mutant p53 to restore its wild‑type structure and function. It was previously demonstrated that PRIMA‑1 effectively inhibited the growth of colorectal cancer (CRC) cells in a p53‑independent manner, and distinctly induced apoptosis by upregulating Noxa in p53‑mutant cell lines. The present study including experiments of western blotting, acridine orange staining and transmission electron microscopy revealed that PRIMA‑1 induced autophagy in CRC cells independently of p53 status.

Changes in the phosphorylation of nucleotide metabolism‑associated proteins by leukemia inhibitory factor in mouse embryonic stem cells.

Mol Med Rep 2021 Jun 13;23(6). Epub 2021 Apr 13.

Department of Microbiology, Jeonbuk National University Medical School, Jeonju, Jeollabuk 54896, Republic of Korea.

Leukemia inhibitory factor (LIF) is a stem cell growth factor that maintains self‑renewal of mouse embryonic stem cells (mESCs). LIF is a cytokine in the interleukin‑6 family and signals via the common receptor subunit gp130 and ligand‑specific LIF receptor. LIF causes heterodimerization of the LIF receptor and gp130, activating the Janus kinase/STAT and MAPK pathways, resulting in changes in protein phosphorylation. Read More

An engineered ligand trap inhibits leukemia inhibitory factor as pancreatic cancer treatment strategy.

Commun Biol 2021 Apr 12;4(1):452. Epub 2021 Apr 12.

Cancer Biology Program, Stanford University School of Medicine, Stanford, CA, USA.

Leukemia inhibitory factor (LIF), a cytokine secreted by stromal myofibroblasts and tumor cells, has recently been highlighted to promote tumor progression in pancreatic and other cancers through KRAS-driven cell signaling. We engineered a high affinity soluble human LIF receptor (LIFR) decoy that sequesters human LIF and inhibits its signaling as a therapeutic strategy. This engineered 'ligand trap', fused to an antibody Fc-domain, has ~50-fold increased affinity (~20 pM) and improved LIF inhibition compared to wild-type LIFR-Fc, potently blocks LIF-mediated effects in pancreatic cancer cells, and slows the growth of pancreatic cancer xenograft tumors.

Inhibitory Smads suppress pancreatic stellate cell activation through negative feedback in chronic pancreatitis.

Ann Transl Med 2021 Mar;9(5):384

Institute of Pancreas, Southeast University, Nanjing, China.

Background: Activation of pancreatic stellate cells (PSCs) is a key cause of chronic pancreatitis (CP), while inhibition of transforming growth factor-β (TGF-β) signaling renders PSCs inactive. Inhibitory Smads (I-Smads) impede TGF-β intracellular signaling and may provide a way to alleviate CP. Thus, we aimed to investigate the molecular mechanism of I-Smads in CP animals and freshly-isolated PSCs. Read More

Chondroitinase ABC Promotes Axon Regeneration and Reduces Retrograde Apoptosis Signaling in Lamprey.

Front Cell Dev Biol 2021 25;9:653638. Epub 2021 Mar 25.

Shriners Hospitals Pediatric Research Center (Center for Neural Repair and Rehabilitation), Lewis Katz School of Medicine at Temple University, Philadelphia, PA, United States.

Paralysis following spinal cord injury (SCI) is due to failure of axonal regeneration. It is believed that axon growth is inhibited by the presence of several types of inhibitory molecules in central nervous system (CNS), including the chondroitin sulfate proteoglycans (CSPGs). Many studies have shown that digestion of CSPGs with chondroitinase ABC (ChABC) can enhance axon growth and functional recovery after SCI. Read More
