Puromycin-sensitive aminopeptidase limits MHC class I presentation in dendritic cells but does not affect CD8 T cell responses during viral infections (2008)

Towne, Charles Fenton, York, Ian A., Neijssen, Joost J., Karow, Margaret L., Murphy, Andrew J., Valenzuela, David M., ...

Previous experiments using enzyme inhibitors, cell lysates, and purified enzyme have suggested that puromycin-sensitive aminopeptidase (PSA) plays a role in creating and destroying MHC class...

Leucine aminopeptidase is not essential for trimming peptides in the cytosol or generating epitopes for MHC class I antigen presentation (2005)

Towne, Charles Fenton, York, Ian A., Neijssen, Joost J., Karow, Margaret L., Murphy, Andrew J., Valenzuela, David M., ...

To detect viral infections and tumors, CD8+ T lymphocytes monitor cells for the presence of antigenic peptides bound to MHC class I molecules. The majority of MHC class I-presented peptides are...

Four human carcinoma cell lines with novel mutations in position 12 of c-K-ras oncogene (1986)

Valenzuela, David M., Groffen, John

We have used synthetic oligonucleotides to probe for mutations affecting amino add 12 of the c-K-ras gene in human cell line DNA. Of seven carcinoma cell lines tested,four were found to contain a...

Angiopoietins 3 and 4: Diverging gene counterparts in mice and humans

Valenzuela, David M., Griffiths, Jennifer A., Rojas, Jose, Aldrich, Thomas H., Jones, Pamela F., Zhou, Hao, ...

The angiopoietins have recently joined the members of the vascular endothelial growth factor family as the only known growth factors largely specific for vascular endothelium. The angiopoietins...

Haploinsufficiency of delta-like 4 ligand results in embryonic lethality due to major defects in arterial and vascular development

Gale, Nicholas W., Dominguez, Melissa G., Noguera, Irene, Pan, Li, Hughes, Virginia, Valenzuela, David M., ...

Vascular development depends on the highly coordinated actions of a variety of angiogenic regulators, most of which apparently act downstream of vascular endothelial growth factor (VEGF). One...

Resistance to diet-induced obesity in mice globally overexpressing OGH/GPB5

Macdonald, Lynn E., Wortley, Katherine E., Gowen, Lori C., Anderson, Keith D., Murray, Jane D., Poueymirou, William T., ...

We identified a glycoprotein hormone β-subunit (OGH, also called GPB5) that, as a heterodimer with the α-subunit GPA2, serves as a second ligand for the thyroid-stimulating hormone receptor. Mice...

Vascular endothelial tyrosine phosphatase (VE-PTP)-null mice undergo vasculogenesis but die embryonically because of defects in angiogenesis

Dominguez, Melissa G., Hughes, Virginia C., Pan, Li, Simmons, Mary, Daly, Christopher, Anderson, Keith, ...

Development of the vascular system depends on the highly coordinated actions of a variety of angiogenic regulators. Several of these regulators are members of the tyrosine kinase superfamily,...

CD133 expression is not restricted to stem cells, and both CD133+ and CD133– metastatic colon cancer cells initiate tumors

Shmelkov, Sergey V., Butler, Jason M., Hooper, Andrea T., Hormigo, Adilia, Kushner, Jared, Milde, Till, ...

Colon cancer stem cells are believed to originate from a rare population of putative CD133+ intestinal stem cells. Recent publications suggest that a small subset of colon cancer cells expresses...

Alternatively activated macrophage-derived RELM-α is a negative regulator of type 2 inflammation in the lung

Nair, Meera G., Du, Yurong, Perrigoue, Jacqueline G., Zaph, Colby, Taylor, Justin J., Goldschmidt, Michael, ...

Differentiation and recruitment of alternatively activated macrophages (AAMacs) are hallmarks of several inflammatory conditions associated with infection, allergy, diabetes, and cancer. AAMacs are...
