    • How a claim becomes a fact: - Voorhoeve, 2006: “These miRNAs neutralize p53- mediated CDK inhibition, possibly through direct inhibition of the expression of the tumorsuppressor LATS2.” - Kloosterman and Plasterk, 2006: “In a genetic screen, miR-372 and miR-373 were found to allow proliferation of primary human cells that express oncogenic RAS and active p53, possibly by inhibiting the tumor suppressor LATS2 (Voorhoeve et al., 2006).” - Yabuta et al., 2007: “[On the other hand,] two miRNAs, miRNA-372 and-373, function as potential novel oncogenes in testicular germ cell tumors by inhibition of LATS2 expression, which suggests that Lats2 is an important tumor suppressor (Voorhoeve et al., 2006).” - Okada et al., 2011: “Two oncogenic miRNAs, miR-372 and miR-373, directly inhibit the expression of Lats2, thereby allowing tumorigenic growth in the presence of p53 (Voorhoeve et al., 2006).”Monday, April 2, 2012

    • Research Questions: 1. Can we find a model for epistemic evaluation and knowledge attribution to describe all biological statements in a straightforward way? 2. If yes: can we detect this evaluation - manually, and automatically? 3. Is this model useful for examining the mechanism of ‘hedging erosion’, does it show how a claim becomes validated after being cited?Monday, April 2, 2012

    • Experimental Discourse Both seminomas and the EC component of nonseminomas share features with ES cells. To exclude that the detection of miR-371-3 merely reflects its expression pattern in ES cells, we tested by RPA miR-302a-d, another ES cells-specific miRNA cluster (Suh et al, 2004). In many of the miR-371-3 expressing seminomas and nonseminomas, miR-302a-d was undetectable (Figs S7 and S8), suggesting that miR-371-3 expression is a selective event during tumorigenesis.Monday, April 2, 2012

Raver-Shapira et.al, JMolCell 2007 Therefore, these results point to two miRNAs, miRNA-372 and-373, function as LATS2 as a mediator of the miR-372 and potential novel oncogenes in testicular germ miR-373 effects on cell proliferation and cell tumors by inhibition of LATS2 expression, tumorigenicity, which suggests that Lats2 is an important tumor suppressor (Voorhoeve et al., 2006).
