Loss of the INK4a/ARF/INK4b locus on chromosome 9p21 is among the most frequent cytogenetic events in human cancer. The products of the locus--p15(INK4b), p16(INK4a), and ARF--play widespread and independent roles in tumor suppression. Recent data also suggest that expression of p16(INK4a) induces an age-dependent decrease in the proliferative capacity of certain tissue-specific stem cells and ...
ANRIL is a recently discovered long non-coding RNA encoded in the chromosome 9p21 region. This locus is a hotspot for disease-associated polymorphisms, and it has been consistently associated with cardiovascular disease, and more recently with several cancers, diabetes, glaucoma, endometriosis among other conditions. ANRIL has been shown to regulate its neighbor tumor suppressors CDKN2A/B by ep...
'Human T Cell Receptor Beta Variable (TRBV) Genes', the seventh report of the 'IMGT Locus on Focus' section, comprises four tables: (1) 'Number of human germline TRBV genes at 7q35 and potential repertoire'; (2) 'Human germline TRBV genes at 7q35'; (3) 'Human TRBV orphons on chromosome 9 (9p21)', and (4) 'Human TRBV allele table'. These tables are available at the IMGT Marie-Paule page from IMG...
Chronic myelogenous leukemia (CML) is characterized by the Philadelphia (Ph) chromosome, created by a reciprocal translocation t(9:22)(q34;q11) which forms the chimeric gene, BCR-ABL. Variant Ph chromosome translocations involving chromosomes other than 9 and 22 have been identified in 5-10% of CML cases. Four-way Ph chromosome translocations are an extremely rare event in myeloid malignancies ...
DNA copy number changes were studied by comparative genomic hybridization on 10 tumor specimens of squamous cell carcinoma of cervix obtained from Korean patients. DNA was extracted from paraffin-embedded sections after removal of non-malignant cells by microdissection technique. Copy number changes were found in 8/10 tumors. The most frequent changes were chromosome 19 gains (n=6) and losses o...
Several families have been reported with autosomal-dominant frontotemporal dementia (FTD) and amyotrophic lateral sclerosis (ALS), genetically linked to chromosome 9p21. Here, we report an expansion of a noncoding GGGGCC hexanucleotide repeat in the gene C9ORF72 that is strongly associated with disease in a large FTD/ALS kindred, previously reported to be conclusively linked to chromosome 9p. T...
Mouse and human cells have most frequently been used for studies that have led to the elucidation of various molecular pathways involved in senescence. The ARF-p53 pathway has been assigned as one of the major protagonists in these phenomena. ARF is an alternative reading frame protein encoded along with p16INK4A by the INK4a locus on human chromosome 9p21 and the corresponding locus on mouse c...
We previously reported frequent loss of heterozygosity on chromosome 9p in esophageal carcinomas and suggested that a tumor suppressor gene located on this chromosomal arm might be involved in development of these cancers. Since recently published studies have shown that a gene mapped on chromosome 9p21, MTS1/CDK4I (multiple tumor suppressor 1/cyclin-dependent kinase 4 inhibitor), is frequently...
