To determine the status of the HIV epidemic in the United States and Canada.We used data on AIDS and HIV diagnoses for 1996-2005 reported to the United States and Canadian national surveillance systems to determine trends in AIDS and HIV (33 US states only) diagnoses and to identify population groups most affected by HIV. HIV incidence for Canada was determined using back-calculation methods. We also determined the proportion of persons diagnosed late (HIV diagnosis within 12 months before AIDS diagnosis). ...

Abstract Suppression subtractive hybridization (SSH) was applied to identify differentially expressed genes in the SV40LT immortalized human bronchial epithelial cell line Y‐BE, with normal human bronchial epithelial cells (HBEC) as a control. Two cDNA libraries of up‐ and downregulated genes were generated, comprising 218 known genes and 131 unknown genes in total. The expression of 22 clones from the 2 libraries was investigated by Northern blot analysis, and 86.4% (19/22) of them showed differential ...

In the present study, we used 22 microsatellite markers flanking to or within 13 known or candidate tumor suppressor genes (TSGs) to detect loss of heterozygosity (LOH) in these chromosomal regions among 41 cases of non-small cell lung cancer, including 28 squamous cell carcinoma (SCC) and 13 adenocarcinoma (ADC). The studied TSGs comprised FHIT, VHL, APC, PRLTS, p16, IFNA, PTEN, p57, ATM, p53, BRCA1, DPC4 and DCC. Our data demonstrated frequent allelic losses of FHIT, p53, IFNA, VHL and p16 in both ...

We detected tumor-associated aberrant hypermethylation of the p16 gene in plasma DNA from 105 non-small cell lung cancer (NSCLC) patients (65 squamous cell carcinoma (SCC) and 40 adenocarcinoma (ADC)) and 92 matched tumor DNA samples, using a modified semi-nested methylation-specific PCR (MSP). This technique increased the sensibility of detecting p16 hypermethylation from DNA samples in varying stages. p16 hypermethylation was present in 73.3% (77/105) of the plasma samples, and 79.3% (73/92) of the tumor ...

Promoter hypermethylation of the p16INK4a gene was investigated in 111 cases of tumor tissue, as well as in 136 circulating plasma and 95 sputum samples from Chinese patients with primary lung cancer, using a modified protocol of semi-nested methylation-specific-PCR (MSP). The results showed hypermethylated p16 sequence in 80.2% of tumor tissues and frequencies of 75.7 and 74.7% in plasma and sputum specimens, respectively. Among the patients, 50 cases of matched plasma, sputum and tumor tissue from ...

Summary Promoter methylation is a common phenomenon in tumours, including haematological malignancies. In the present study, we investigated 36 cases of high hyperdiploid (>50 chromosomes) acute lymphoblastic leukaemia (ALL) with methylation‐specific multiplex ligase‐dependent probe amplification to determine the extent of aberrant methylation in this subgroup. The analysis, which comprised the promoters of 35 known tumour suppressor genes, showed that 16 genes displayed abnormal methylation in at ...

The ETV6-RUNX1 fusion is the molecular consequence of the t(12;21)(p13;q22) seen in approximately 25% of children with acute lymphoblastic leukemia (ALL). Studies have shown that the fusion alone is insufficient for the initiation of leukemia; additional genetic changes are required. Genomic profiling identified copy number alterations at high frequencies in these patients. Focal deletions of TBL1XR1 were observed in 15% of cases; 3 patients exhibited deletions distal to the gene. Fluorescence in ...

The probabilities were applied to a hypothetical cohort of 10 million live births, and estimates were derived for the lifetime risk, from birth, of being diagnosed ...

The search for target genes involved in unbalanced acquired chromosomal abnormalities has been largely unsuccessful, because the breakpoints of these rearrangements are too variable. Here, we use the example of dicentric chromosomes in B cell precursor acute lymphoblastic leukemia to show that, despite this heterogeneity, single genes are targeted through a variety of mechanisms. FISH showed that, although they were heterogeneous, breakpoints on 9p resulted in the partial or complete deletion of ...
