Human lung carcinoma stained with anti-GLUT-1 antibody

GLUT-1




Glucose transporter 1 (or GLUT1), also known as solute carrier family 2, is a protein facilitating the transport of glucose across the plasma membranes of mammalian cells. Several GLUT isoforms have been identified and shown to function in response to insulin and IGF-1 induced signaling. GLUT-1 is detectable in many human tissues including colon, lung, stomach, esophagus, and breast. GLUT-1 is up-regulated in some human cancers from these organs.




Human breast carcinoma stained with anti-EphA2 antibody

EphA2




Ephrin type-A receptor 2 (EphA2) is a protein-tyrosine kinase in the ephrin receptor subfamily. EphA2 plays a role for angiogenesis and tumor neovascularization. High levels of EphA2 protein expression can be detected in some tumor cells such as breast carcinoma, bladder carcinoma, renal cell carcinoma (RCC), and non-small cell lung carcinoma (NSCLC). Inhibition of EphA2 kinase activity is considered for the treatment of various tumors such as RCC and NSCLC.




Human colon stained with anti-SMA antibody

Smooth muscle actin-alpha (SMA) is a cytoskeleton protein in smooth muscle cells and their derived tumors such as leiomyoma and leiomyosarcoma. It is also expressed in myoepithelial cells of the breast and salivary gland, but not in fibroblasts, striated muscle, and myocardium.




Human colon adenocarcinoma stained with anti-GIV antibody

GIV




Girdin (girders of actin filaments), also known as APE and GIV, is a widely expressed cytosolic protein and plays a key modulating role for the AKT-mTOR signaling pathway. Girdin is membrane-associated and interacts with phosphoinositides. It relocates to cytoplasm where it cross-links actin filaments after its phosphorylation at Ser1417 by Akt. It enhances phosphoinositide 3-kinase (PI3K)-dependent phosphorylation and kinase activity of AKT1/PKB. It is essential for the integrity of the actin cytoskeleton and for cell migration. Four isoforms of Girdin have been reported.




SK-MEL-2 cells stained with anti-N-Ras (Q61R) antibody

N-Ras (Q61R)




GTPase N-Ras or N-Ras is a guanine-nucleotide binding protein. Receptor tyrosine kinases and G-protein-coupled receptors activate Ras, which then stimulates the MAPK signal pathway. Point mutations (Q61R) in Ras prevent the GAP-mediated inhibition of the MAPK pathway in certain cancers such as lung carcinoma and melanoma. Abnormal MAPK signaling may lead to uncontrolled cell proliferation, resistance to both apoptosis and cancer therapy.

CD25 is expressed on activated T cells, activated B cells, some thymocytes, myeloid precursors, oligodendrocytes, and most B cell neoplasms, some acute nonlymphocytic leukemias, neuroblastomas, and tumor infiltrating lymphocytes.




Human prostate adenocarcinoma stained with anti-MAP4K4 antibody

It directly phosphorylates and activates the c-Jun N-terminal kinase (JNK) and p38 families of MAP kinases in response to various stimulating factors. It involves the mediation of TNF-alpha signaling pathway. MAP4K4 is overexpressed in many types of human cancer such as carcinoma of prostate, ovarian, liver, and pancreas.
