To understand the survival of dormant, nonculturable H. pylori, we investigated changes in cell morphology and gene transcription associated with the loss in culturability seen under oxygen stress and nutrient deprivation. This study examined the gene transcription profiles associated with the trans...

Luteinizing hormone (LH) activation of the EGF receptor/RAS/ERK1/2 pathway is essential for ovulation and luteinization because granulosa cell depletion of Erk1/2 (Erk1/2gc-/- mice) renders mice completely infertile. Because of their potential as mediators of ERK1/2-dependent granulosa cell differe...

A surge of luteinizing hormone (LH) from the pituitary gland triggers ovulation, oocyte maturation, and luteinization for successful reproduction in mammals. Since the signaling molecules RAS and ERK1/2 are activated by a LH surge in granulosa cells of preovulatory follicles, we disrupted Erk1/2 in ...

The functional status of the tumor repressor protein (TP53 or TRP53) is a defining feature of ovarian cancer. Mutant or null alleles of TP53 are expressed in greater than 90% of all high-grade serous adenocarcinomas. Wild type TP53 is elevated in low-grade serous adenocarcinomas in women and in our ...

How signals from fatty acid metabolism are translated into changes in food intake remains unclear. Previously we reported that mice with a genetic inactivation of Acads (short-chain acyl-CoA dehydrogenase), encoding the enzyme responsible for mitochondrial beta-oxidation of C4-C6 short-chain fatty ...

The specific genes influencing the quantitative variation in macronutrient preference and food intake are virtually unknown. We refined a previously identified mouse chromosome 17 (MMU17) region harboring quantitative trait loci (QTL) with large effects on preferential macronutrient intake-carbohyd...
