Cell-Surface Vimentin Monoclonal Antibody

Vimentin, a 57kDa type III intermediate filament, is responsible for architecture of cytoplasm.1 As a popular intracellular epithelial mesenchymal transition (EMT) marker, overexpression of vimentin in cancer cells was known for its high correlation with cancer progression. Apart from secretion under some circumstances, vimentin can also be recruited to the cell surface, known as cell surface vimentin (CSV), to participate in cell adhesion, migration and cellular signaling.2 The significance of CSV is related to its involvement in autoimmune disorders, viral infection and cancer. CSV expression on activated marcophages, platelets and apoptotic T lymphocytes evidenced its connection to human neutrophil spontaneous apoptosis further supports its association with inflammatory diseases.3 Being a putative anti-viral drug target, CSV also takes parts in viral multiplication by directly facilitate internalization of virion.4 Recently, breakthroughs on identifying CSV as cancer specific EMT marker, in association with metastatic phenotypes in aggressive cancer and sarcoma, has made an impact on cancer research community. Because unlike intracellular vimentin, the cell surface detection of CSV enables the isolation of cancer cells.5,6,7 Abnova obtains worldwide exclusive license of the patented CSV monoclonal antibody, clone 84-1, from MD Anderson Cancer Center, United States. This antibody has been validated for its intended use in majorities of cancer cell lines by both immunofluoresence and flow cytometry.8 As a sole provider for this powerful tool, Abnova hopes to propel the investigations on cancer research with specificity and broad applicability.

Hematopoiesis

New Discoveries on Hematopoiesis Hematopoietic stem cell (HSC) is generated from the hemogenic endothelium (HE), where HE and arterial vascular endothelium (VE) was found to represent separate lineages, on the basis of differential expression of CD73 and CD184. (Nature Cell Biology, 2015) HSC regenerative capacity was increased through the inactivation of a histone deacetylase, SIRT7.

Kiss of Death - Ubiquitylation

New Discoveries on Ubiquitylation Elongation of ubiquitin chain, regardless of the linkage, can form polyubiquitin fibrils to initiate autophagy pathway. Incapacity of autophagy can cause cytotoxic accumulation of ubiquitin-positive aggregates leading to neurodegenerative diseases. (Nature communication,2015) Highly expressed in human breast and lung cancers, a new deubiquitinating enzyme, USP36, was identified to regulate c-Myc oncoprotein stability in nucleolus. (PNAS,2015) Itch, an E3 HECT ubiquitin ligase, inhibits MAPK p38α activation through ubiquitylation can be exploited therapeutically to prevent chronic skin inflammation.
