We analysed whether MSI (MicroSatellite Instability) and/or CIN (Chromosome INstability = LOH (loss of heterozygosity) and/or DNA-aneuploidy

(abnormal nuclear DNA contents)) could be used as predictors of familial CRC.

Formalin-fixed tissue from 97 patients with CRC (29 patients with 2 or more affected first-degree relatives (= “”cases”"), 29 matched CRC controls without a family history, and 39 relatives to cases) were analysed for MSI and CIN.

In this small case-control study, no significant differences in the frequencies of MSI and CIN were observed between cases with a family history and their controls without a family history. MSI+;CIN- was observed in 6/29 cases and in 0/29 controls (p = 0.02), most frequently in cases with affected 3-deazaneplanocin A price siblings, only (3/7). However, for 13 patients from whom several CRC tumours were analysed, concordant results for MSI/LOH/DNA-ploidy were obtained only in 10/9/9. Among cases and relative(s), concordant

results for MSI, LOH and DNA-ploidy were obtained in 16/26, 16/26, and 14/25 families, respectively.

Although MSI+;CIN-appeared to predict familial CRC with a high specificity, neither MSI, CIN, or MSI+;CIN- are likely to be sufficiently sensitive predictors of familial CRC.”
“Background: One of the histone acetyltransferases (HATs) family GSK1838705A of proteins, human MOF (hMOF, MYST1), is involved in histone H4 acetylation, particularly at lysine 16 (H4K16Ac), an epigenetic mark of active

genes. Dysregulation of the epigenetic mark influences cellular biology and possibly leads to oncogenesis. We examined the involvement of hMOF and H4K16Ac in primary non-small cell lung cancer (NSCLC). Methods: Reverse transcription polymerase chain reaction using fresh-frozen lung cancer tissues and lung cancer cell lines and immunohistochemistry for hMOF and H4K16Ac via tissue microarray of 551 formalin-fixed paraffin-embedded NSCLC tissue blocks were conducted. Results: hMOF mRNA was frequently overexpressed in lung cancer tissues, compared with normal lung tissues (10/20, 50%). NSCLC tissues were positive for hMOF in 37.6% (184/489) and H4K16Ac in 24.7% (122/493) of cases. hMOF protein expression was tightly correlated with the H4K16Ac level in tumors (p<0.001). P505-15 ic50 Knockdown of hMOF mRNA with siRNA led to a significant inhibition of growth in the Calu-6 cell line. Conclusions: hMOF was frequently expressed in NSCLC and was correlated with H4K16Ac. To our knowledge, this is the first study that has focused on the expression status of HATs and hMOF in NSCLC. Our results clearly suggest a potential oncogenic role of the gene and support its utility as a potential therapeutic target.”
