Despite the late take, the VEGF-Cys51Ser and VEGF-Cys60Sertumors developed an extensive vascular bed with an architecture comparable to that of recombinant wtVEGF-producing tumors whereas control tumors had a considerably lower vascular density.
A type 2C pVHL mutant (V188L), which is associated with a PHE only phenotype (and had been shown previously to retain the ability to promote HIF ubiquitylation), retained the ability to suppress CCND1expression suggesting that loss of pVHL-mediated suppression of cyclin D1 is not necessary for PHE development in VHL disease.

CD-31 (platelet-endothelial cell adhesion molecule [PECAM]) staining revealed that blood vessels developed in tumors larger than 1 mm The administration of P125A human endostatin in C3(1)/Tag females resulted in a significant delay in tumor onset, decreased tumor multiplicity and tumor burden and prolonged survival of the animals.
These results demonstrate that P125A endostatin inhibits the angiogenic switch during mammary gland adenocarcinoma tumor progression in the C3(1)/Tag transgenic model.

We established an in vitro model consisting of stroma expressing mutant p53 (Cys135Ser) to study its ability to support growth of cells from a pre-B acute lymphoblastic leukemia (ALL) cell line.

To directly assess its role in tumor growth and metastasis in vivo, we stably transfected HT-1080 fibrosarcoma cells expressing either fully active wild-type human TFPI-2 (WT) or inactive R24Q TFPI-2 (QT) and examined their ability to form tumors and metastasize in athymic mice in comparison to mock-transfected cells (MT).

In this matched cohort study, VHL 598C>T homozygosity was associated with vertebral hemangiomas, varicose veins, lower blood pressures, and elevated serum vascular endothelial growth factor (VEGF) concentrations (P <.0005), as well as premature mortality related to cerebral vascular events and peripheral thrombosis.
Chuvash polycythemia is a hypoxia-sensing disorder characterized by homozygous mutation (598C>T) of von Hippel-Lindau gene (VHL), a negative regulator of hypoxia sensing.

P125A-endostatin also localised into tumour tissue to a higher degree than the native protein, and displayed greater inhibition of growth of colon cancer in athymic mice.

All patients with BD and controls were genotyped by polymerase chain reaction and allele-specific oligonucleotide techniques for +936 C/T (rs3025039) and -634 C/G (rs2010963) mutations and for an 18 base pair (bp) insertion/deletion (I/D) polymorphism at -2549 of the the VEGF promoter region.
While G-1877A, T-1455C, G-1154A, C702T, and G1612A were not detected, C-2578A, T-1498C, G-1190A, C-634G, C-7T, C936T, and C1451T were found at allele frequencies of 4/36, 15/36, 15/36, 20/36, 8/36, 6/36, and 6/36, respectively, suggesting that C-2578A, G-1154A, and G1612A were associated with a decreased risk for colorectal adenocarcinoma.
GSTM1-negative, GSTT1-positive, and hOGG1 Ser326Ser and Ser326Cys genotypes are risk factors for bladder cancer (P = 0.020, P = 0.044, and P = 0.012, respectively).
