Description
Mammalian gonadal sex determination is dependent on proper expression of sex determining genes in fetal gonadal somatic support cells (i.e., pre-granulosa and pre-Sertoli cells in XX and XY gonads, resp.). We used a unique transgenic mouse strain combined with microarray profiling to identify all the differentially expressed transcripts in XX and XY isolated somatic support cells during critical stages of gonadal development and differentiation.

Description
Mesoderm differentiation in zebrafish relies on a complex interaction between transcription factors and signaling pathways. Tbx16 is a t-box transcription factor involved in this interaction. Here, we examine downstream targets of tbx16 in the intermediate mesoderm at the 4/5-somite stage and tail mesoderm at the 21-somite stage by comparing wild-type tissues with tissues from the tbx16 mutant, spadetail (spt).

Description
A soy diet worsens the progression of an inherited form of hypertrophic cardiomyopathy (HCM) in male mice when compared to casein-fed mice. Females are largely resistant to this diet effect and better preserve cardiac function. We hypothesized that the abundant phytoestrogens found in soy are mainly responsible for this diet-dependent phenotype. Indeed, feeding male mice a phytoestrogen-supplemented casein-based diet can recapitulate the negative outcome seen when male mice are fed a standard soy-based diet.
Publication Title
Estrogenic compounds are not always cardioprotective and can be lethal in males with genetic heart disease.

Description
Increasing evidence suggests that microRNAs may play important roles in regulating self-renewal and differentiation in mammalian stem cells (SCs). Here, we explore this issue in skin. We first characterize microRNA expression profiles of skin SCs versus their committed proliferative progenies and identify a microRNA subset associating with stemness. Of these, miR-125b is dramatically downregulated in early SC-progeny. We engineer an inducible mice system and show that when miR-125b is sustained in SC-progenies, tissue balance is reversibly skewed towards stemness at the expense of epidermal, oil-gland and HF differentiation. Using gain-and-loss of function in vitro, we further implicate miR-125b as a repressor of SC differentiation. In vivo, transcripts repressed upon miR-125b induction are enriched >700% for predicted miR-125b targets normally downregulated upon SC-lineage commitment. We verify some of these miR-125b targets, and show that Blimp1 and VDR in particular can account for many tissue imbalances we see when miR-125b is deregulated.

Description
We identify numerous miR-203 in vivo targets that are highly enriched for the promotion of cell cycle and cell division. Importantly, individual targets including p63, Skp2 and Msi2 play distinct roles downstream of miR-203 to regulate the cell cycle and long-term proliferation. Together, our findings reveal rapid and widespread impact of miR-203 on the self-renewal program during the epidermal differentiation and provide mechanistic insights for the potent role of miR-203 where coordinated repression of multiple targets is required for the function of this miRNA.
