Popis: (a) Colon cancer is the second most lethal cancer and is predicted to claim 50,310 lives in 2014. Chromosome Instability (CIN) is observed in 80-90% of colon cancers and is thought to contribute to colon cancer progression and recurrence. We developed animal models focusing on mitotic error-induced CIN, Shugoshin-1 (Sgo1) haploinsufficient (-/+) mice, to investigate the impact of CIN on colon cancer development. Sgo1-/+ mice showed altered profiles in colonic lesions and cancer development. In this study, we analyzed signature changes in the colonic transcriptome of Sgo1-/+ mice to investigate underlying molecular events in the altered carcinogenesis profiles. (b) We treated control and Sgo1-/+ mice with colonic carcinogen azoxymethane (AOM), and tracked colon cancer development 12, 24, and 36 weeks after AOM treatments. We performed Next Generation Sequencing (NGS)-based transcriptome analysis at 24 weeks. (c) There were 349 hits with 2-fold expression difference threshold, P (d) Systemic Chromosome Instability resulted in transcriptomic changes in metabolic and proliferation regulators in the colon. We propose that the CIN effect may be countered through manipulation of these pathways. Citation Format: Chinthalapally V.
