sarcoma/proline

A microcytoxicity assay with 3H-proline prelabeled target cells was used for the detection of sensitized lymphoid spleen cells from STU inbred mice inoculated with Moloney sarcoma virus (MSV-M) or ascitic MSV-M tumor cells. The target cell line was derived from ascitic MSV-M tumor cells. With regard

The Kaposi's sarcoma-associated herpesvirus (KSHV) (also known as human herpesvirus 8) has been implicated in the pathogenesis of Kaposi's sarcoma and B cell primary effusion lymphomas. KSHV encodes a G protein-coupled receptor (GPCR) that acts as an oncogene and constitutively activates two protein

Mutations in the proline/tyrosine-nuclear localization signal (PY-NLS) of the Fused in Sarcoma protein (FUS) cause amyotrophic lateral sclerosis (ALS). Here we report the crystal structure of the FUS PY-NLS bound to its nuclear import receptor Karyopherinβ2 (Kapβ2; also known as Transportin). The

The matrix (M) protein of rhabdoviruses has been shown to play a key role in virus assembly and budding; however, the precise mechanism by which M mediates these processes remains unclear. We have associated a highly conserved, proline-rich motif (PPxY or PY motif, where P denotes proline, Y

EWS expression in Ewing sarcoma family tumors (ESFTs) is decreased due to the haploinsufficiency elicited by chromosomal translocation. The abnormal expression levels of EWS and its downstream factors contribute to the manifestation of ESFTs. Previously, we reported that increased Proline-rich Akt

Radioactive proline-labeled procollagen, accumulated during a 3-hr incubation of normal and transformed BALB 3T3 cultures, was treated with pepsin and the resulting collagen components were analyzed by carboxymethyl-cellulose chromatography and sodium dodecyl sulfate/polyacrylamide gel

System A amino acid transport is increased in transformed and malignant cells. The amino acid 4-cis[(18)F]fluoro-l-proline (cis-[(18)F]FPro) has been shown to be a substrate of the System A amino acid carrier. In this pilot study, we investigated the diagnostic potential of cis-[(18)F]FPro in

Cytokines produced in the tumour microenvironment exert an important role in cancer pathogenesis and in the inhibition of disease progression. Cancer of the cartilage is termed metastatic chondrosarcoma; however, the signaling events resulting in mesenchymal cell transformation to sarcoma have yet

The participation of B cells in cell-mediated cytotoxicity (CMC) for allogeneic and syngeneic murine sarcoma cells induced with 3-methylcholanthrene was investigated. Primed nonadherent peritoneal cells (NAPC) were treated with antisera against lymphocyte surface antigens and complement, and

The fusion peptide of the avian sarcoma/leukosis virus (ASLV) envelope protein (Env) is internal, near the N terminus of its transmembrane (TM) subunit. As for most internal viral fusion peptides, there is a proline near the center of this sequence. Robson-Garnier structure predictions of the ASLV

The cytolysis of 3H-proline-labelled tumour cells growing in monolayer by syngeneic immune lymphocytes has been studied in the murine sarcoma virus (MSV) system. Results show that the proline assay (PA) is a convenient way to reveal the activity of cytolytic T lymphocytes against FMR-like antigens.

The Gag protein of Rous sarcoma virus has the ability to direct particle assembly at the plasma membrane in the absence of all the other virus-encoded components. An extensive deletion analysis has revealed that very large regions of this protein can be deleted without impairing budding and has
