We explored potential bypass mechanisms to PI3K/mTOR-directed therapy in KRAS mutant CRC models, utilizing genetically engineered mouse models (GEMM) to generate acquired resistance to the targeted dual PI3K/mTOR small molecule inhibitor PF-04691502. Transcriptomic analysis revealed a dynamic stem-l...

RNA-Seq is a powerful tool for transcriptome profiling, but is hampered by sequence-dependent bias and inaccuracy at low copy numbers intrinsic to exponential PCR amplification. We developed a simple strategy for mitigating these complications, allowing truly digital RNA-Seq. Following reverse tra...

Irradiation of the K-rasLA1 mouse model with a fractionated dose of 1.0Gy 56Fe- particles increases the incidence of invasive carcinoma compared to unirradiated controls or those irradiated with an acute dose. Microarray profiling was perfromed on whole lungs from K-rasLA1 mice in order to determin...

As a central component during Okazaki fragment maturation, flap endonuclease 1 (FEN1) removes the 5’ flap and maintains genomic stability. Here, FEN1 was cloned as a suppressor of transcriptional gene silencing (TGS) from a forward genetic screen. FEN1 is abundant in the root and shoot apical meri...

We investigated the transcriptional response to thiamethoxam in the Bemisia tabaci using Illumina sequencing technology. A total of 1,338 genes were differently expressed in the thiamethoxam-resistant whiteflies. All the B biotype whiteflies were maintained on cabbage. The susceptible strain (TH-S)...

The molecular mechanisms of acute lung injury are incompletely understood. MicroRNAs (miRNAs) are crucial biological regulators that act by suppressing their target genes and are involved in a variety of pathophysiologic processes. MiR-127 appeared to be down-regulated during lung injury. We set out...

3 Cell lines from Apc, p53 (AP) GEMMs were compared to 12 cell lines from Apc, Kras, p53 (AKP) GEMMs. Mouse 430 2.0 arrays were used to determine genomic expression differences between the two genotypes (AP and AKP). RNA was extracted from 3 AP and 10 AKP cell lines using the Qiagen RNEasy kit, and ...
