The role of stem cells in solid tumors remains controversial. In colorectal cancers (CRC), this is complicated by the conflicting top-down or bottom-up hypothesis of cancer initiation. We profiled the expressions of genes from the top (T) and bottom (B) fractions of the crypt in morphologically normal-appearing colonic mucosa (M) and contrasted this to that of matched mucosa adjacent to tumors (MT) in twenty three sporadic CRC patients. In thirteen patients, the genetic distance (M-MT) between the B fractions is smaller than the distance between the T fractions indicating that the expressions of significant genes diverge further in the top fractions (B<T). In the remaining ten patients, the reverse is observed (B>T).
Human colorectal cancer initiation is bidirectional, and cell growth, metabolic genes and transporter genes are early drivers of tumorigenesis.

View SamplesBackground: Causative genes for autosomal dominantly inherited familial adenomatous polyposis (FAP) and hereditary non-polyposis colorectal cancer (HNPCC) have been well characterized. There is, however, another 10-15 % early onset colorectal cancer (CRC) whose genetic components are currently unknown. In this study, we used DNA chip technology to systematically search for genes differentially expressed in early onset CRC.

View SamplesPhysiological, anatomical, and clinical laboratory analytic scoring systems (APACHE, Injury Severity Score (ISS)) have been utilized, with limited success, to predict outcome following injury. We hypothesized that a peripheral blood leukocyte gene expression score could predict outcome, including multiple organ failure, following severe blunt trauma.
