The most thoroughly characterized mammalian IAP is XIAP/BIRC4, which can inhibit caspases 9, 3 and 7, but may also regulate apoptosis through interactions with other proteins such as Smac/DIABLO, HtrA2/Omi, XAF1, TAK1, cIAP1, and cIAP2.High throughput sequencing of the mouse genome revealed the existence of a gene resembling Xiap/Birc4 on mouse chromosome 7. To confirm the existence of this gen...

BACKGROUND Elevated blood pressure (BP) shares a level of heritability similar to many other traits related to cardiovascular risk; however, specific susceptibility loci have been difficult to localize. We conducted a multistage study of BP as a continuous trait in a low-risk West African population in which it was anticipated that environmental exposures would be reduced in complexity and inte...

The relationship between interphase cytogenetics and tumor grade, stage, and proliferative activity was investigated in 27 transitional cell carcinomas of the urinary bladder. Using fluorescence in situ hybridization with chromosome-specific DNA probes, the copy number of pericentromeric sequences on chromosomes 7, 9, and 11 was detected within interphase nuclei in touch preparations from tumor...

Silver-Russell syndrome (SRS MIM180860) is a disorder characterised by intrauterine and/or postnatal growth restriction and typical facies. However, the clinical picture is extremely diverse due to numerous diagnostic features reflecting a heterogeneous genetic disorder. The mode of inheritance is variable with sporadic cases also being described. Maternal uniparental disomy (mUPD) of chromosom...

We studied large Amish/Mennonite/Hutterite kindreds that segregate cystic fibrosis (CF) for linkage between CF and the polymorphic DNA markers pJ3.11 and 7C22 located on chromosome 7. These inbred pedigrees consist of more than 300 members including 30 affected individuals. In these families, linkage between the CF locus and the chromosome 21 marker D21S5 and between CF and the marker at the me...

the chromosomal spread and karyotype of bleak (alburnus alburnus) from anzali lagoon were identified using tissue squashing techniques with injection of 0.5ml/100g body weight of 0.01% colchicines solution in fish fingerlings. kidney and gill tissues were then extracted and chopped in kcl 0.045m for 20 min and fixed in carnoy solution in 3 stages. the chromosomal spreads were stained in 20% gim...

INTRODUCTION To compare the efficacy of silver in situ hybridization (SISH) and immunohistochemistry (IHC) in detecting MET and IGF1R alterations and to investigate their prevalence and prognostic significance. A possible correlation between MET receptor expression, MET gene alterations and the two most frequent occurring EGFR gene mutations was also investigated. MATERIALS AND METHODS Stage ...

The lineage of the Y chromosome accounts for up to 15 to 20 mm Hg in arterial pressure. Genes located on the Y chromosome from the spontaneously hypertensive rat (SHR) are associated with the renin-angiotensin system. Given the important role of the renin-angiotensin system in the renal regulation of fluid homeostasis and arterial pressure, we hypothesized that the origin of the Y chromosome in...

Loss of chromosome 7 (-7) or deletion of the long arm (7q-) are recurring chromosome abnormalities in myeloid leukemias. The association of -7/7q- with myeloid leukemia suggests that these regions contain novel tumor suppressor gene(s), whose loss of function contribute to leukemic transformation or tumor progression. Based on chromosome banding analysis, two critical regions have been identifi...
