Genomic alterations in Reinke's edema

Project description:Reinke's edema (RE) is a laryngeal lesion related to excessive tobacco smoking, voice overuse, and laryngopharyngeal reflux. Although the risk of malignancy is low, RE has been classified among premalignant lesions. Array-based comparative genomic hybridization (aCGH) was used to investigate DNA copy number alterations (CNA) and as a tool to identify markers of risk stratification.

Genomic alterations indicate tumor origin and varied metastatic potential of disseminated cells from prostate cancer

Project description:Disseminated epithelial cells can be isolated from the bone marrow of a far greater frac-tion of prostate-cancer patients than the fraction of patients who progress to metastatic disease. To provide a better understanding of these cells, we have characterized their genomic altera-tions. We first present an array comparative genomic hybridization method capable of detecting genomic changes in the small number of disseminated cells (10-20) that can typically be ob-tained from bone-marrow aspirates of prostate-cancer patients. We show multiple regions of copy-number change, including alterations common in prostate cancer, such as 8p loss, 8q gain, and gain encompassing the androgen-receptor gene on Xq, in the disseminated cell pools from 11 metastatic patients. We found fewer and less striking genomic alterations in the 48 pools of disseminated cells from patients with organ-confined disease. However, we identify changes shared by these samples with their corresponding primary tumors and prostate-cancer altera-tions reported in the literature, evidence that these cells, like those in advanced disease, are disseminated tumor cells (DTCs). We also demonstrate that DTCs from patients with advanced and localized disease share several abnormalities, including losses containing cell-adhesion genes and alterations reported to associate with progressive disease. These shared alterations might confer the capability to disseminate or establish secondary disease. Overall, the spectrum of genomic deviations is evidence for metastatic capacity in advanced-disease DTCs and varia-tion in that capacity in DTCs from localized disease. Our analysis lays the foundation for eluci-dation of the relationship between DTC genomic alterations and progressive prostate cancer.

Landscape of genomic alterations in Indian Urinary Bladder cancer patients

Project description:Urinary bladder is an open system and is under constant carcinogenic insults leading to chromosomal aberrations. Chronic retention of urine in the bladder is considered one of the reasons for initiation of bladder cancer. Here, we have explored the genomic alterations in Indian BlCa patients by CGH-SNP microarray. The microarray data (n=10) revealed several alterations throughout the genome. Genomic regions like 2p25.3 [chr2: 3557810-3575411], 4p16.3 [chr4: 656211-657032], 7p22.3 [chr7: 990730-1000575], 10q26.13 [chr10: 123137874-123148372], 16q24.3 [chr16: 88835825-88837868], 17p11.2 [chr17: 17477220-17506264], 19q13.33 [chr19: 49861971-49862491], 20q13.33 [chr20: 63406442-63415195; 63415195-63495407] etc. were found to be frequently (≥40%) amplified among the 10 BlCa samples. Regions like 2q37.2 [chr2: 235384329- 235479250], 8p23.3-11.21 [chr 8: 236477- 39291988], 10q21.1-26.3 [chr 10: 55309072- 133391562], 11p12 [chr 11: 37327799- 38803561], 12q24.31-24.33 [chr 12: 128515048- 133047983], and 13q13.3-34 [chr 13: 35583974- 113996673] etc. are identified as common deletion (30%). Chromosomal regions like 2p25.3, 16q24.3 and 20q13.33 showed the highest frequency of amplification (70%), whereas 2q37.2, 10q21.1, 11p12, 11q22.3, etc. showed the highest frequency of deletion (30%). Chromosome 7, 15 and 21 showed the least alterations in these samples. Almost a complete loss in 8p chromosomal arm (8p23.1-11.22), chromosome 11q (11q14.1-25) and chromosome 13 (13q13.3-34) were found in 30% of samples, signifying their plausible role in development of BlCa.
