Cancer Stem Cell Marker CD44 Plays Multiple Key Roles in Human Cancers: Immune Suppression/Evasion, Drug Resistance, Epithelial-Mesenchymal Transition, and Metastasis.

OMICS 2021 May;25(5):313-332

Division of Computational Biology, Faculty of Health Sciences, Institute of Infectious Disease and Molecular Medicine, University of Cape Town, Cape Town, South Africa.

One of the most frequently utilized cancer stem cell markers in human cancers, including colorectal cancer and breast cancer, is CD44. A glycoprotein, CD44, traverses the cell membrane and binds to many ligands, including hyaluronan, resulting in activation of signaling cascades. There are conflicting data, however, on expression of CD44 in relationship to subtypes of cancers. Read More

LncRNA PINK1-AS promotes Gαi1-driven gastric cancer tumorigenesis by sponging microRNA-200a.

Oncogene 2021 May 6. Epub 2021 May 6.

Center of Translational Medicine, The Affiliated Zhangjiagang Hospital of Soochow University, Suzhou, China.

Gastric cancer (GC) is one of the leading causes of human mortality around the world. We have previously shown that Gαi1 (the inhibitory subunit 1 of the heterotrimeric guanine nucleotide-binding protein) recruitment to ligand-activated receptor tyrosine kinases (RTKs) is essential for signaling. Testing its role in GC cancer-promoting functions, we found that Gαi1 is upregulated in human GC, correlating with poor overall survival. Read More

EGF and BMPs govern differentiation and patterning in human gastric glands.

Gastroenterology 2021 May 3. Epub 2021 May 3.

Department of Molecular Biology, Max Planck Institute for Infection Biology, Berlin, 10117, Germany; Ludwig Institute for Cancer Research, Nuffield Department of Clinical Medicine, University of Oxford, OX3 7DQ, United kingdom. Electronic address:

Background & Aims: The homeostasis of the gastrointestinal epithelium relies on cell regeneration and differentiation into distinct lineages organised inside glands and crypts. Regeneration depends on WNT/β-Catenin pathway activation, but to understand homeostasis and its dysregulation in disease we need to identify the signalling microenvironment governing cell differentiation.
