... learning algo- rithms consisted of vectors of web hits obtained using the 14 most frequent joining terms found in the BNC. The next condition used a vector of web hits obtained using the joining ... and again using all of the joining terms produced the best results. The SVM algorithm produced the best accuracy of all, achieving 50.1% accuracy using the com- bined set of j...

... not repress the level of PPARc protein in committed prea- dipocytes under physiologically relevant conditions. Expression of miR-27 is elevated in obese mice In order to gain insights into the potential ... We further investigated the kinetics of miR-27 expression during adipogenesis using quantitative real-time PCR. As shown in Fig. 1C,D, expression of both miR-27a and miR-27...
