Abstract
The Bombyx mori sex determination gene Bmdsx is alternatively spliced in the male and female to produce the male- and female-specific proteins. In an effort to better understand the mechanism of the alternative splicing regulation of Bmdsx, we conducted a gel-shift assay followed by LC-MS/MS analysis to identify the putative proteins bound to the cis-element CE1+6 in the exon 4 of Bmdsx. A protein named as BmHrp28 which is homologous to the Drosophila Hrp48, a member of the hnRNPA/B family, was identified and expressed in Escherichia coli for testing RNA-protein binding in vitro. All of the results showed that BmHrp28 specifically bound to the CE1+6 RNA probe. BmHrp28 has two RNA recognition motifs at the N-terminal and a glycine-rich motif at the C-terminal. It might be one of the factors involved in the male-specific splicing of Bmdsx.

Abstract
We report on a combined atomistic molecular dynamics simulation and implicit solvent analysis of a generic hydrophobic pocket-ligand (host-guest) system. The approaching ligand induces complex wetting-dewetting transitions in the weakly solvated pocket. The transitions lead to bimodal solvent fluctuations which govern magnitude and range of the pocket-ligand attraction. A recently developed implicit water model, based on the minimization of a geometric functional, captures the sensitive aqueous interface response to the concave-convex pocket-ligand configuration semiquantitatively.

Abstract
The detection and mapping of genetic markers linked to quantitative trait loci (QTL) can be utilized to enhance genetic improvement of livestock populations. With the completion of the bovine genome sequence assembly, single nucleotide polymorphisms (SNP) assays spanning the whole bovine genome and research work on large scale identification, validation and analysis of genotypic variation in cattle has become possible. The objective of the present study was to perform a whole genome scan to identify and map QTL affecting milk production traits and somatic cell scores using linkage disequilibrium (LD) regression and 1536 SNP markers. Three and 18 SNP were found to be associated with only milk yield (MY) at a genome and chromosome wise significance (p < 0.05) level respectively. Among the 21 significant SNP, 16 were in a region reported to have QTL for MY in other dairy cattle populations and while the rest five were new QTL finding. Four SNP out of 21 are significant for the milk production traits (MY, fat yield, protein yield (PY), and milk contents) in the present study. Six and nine SNP were associated with PY at a genome and chromosome wise significant (p < 0.05) level respectively. Three and 17 SNP were found to be associated with FY at a genome and chromosome wise significant (p < 0.05) level. Five and seven SNP were mapped with somatic cell score at a genome and chromosome wise significant (p < 0.05) level respectively. The results of this study have revealed QTL for MY, PY, protein percentage, FY, fat percentage, somatic cell score and persistency of milk in the Canadian dairy cattle population. The chromosome regions identified in this study should be further investigated to potentially identify the causative mutations underlying the QTL.

Abstract
Emerging evidences suggest that testosterone is an important regulator of body fat mass in men. However, the mechanism underlying the regulation of body composition by testosterone is not well understood. The paper demonstrates testosterone inhibited the activity of peroxisome proliferator-activated receptor gamma (PPARgamma), which controls the adipogenic differentiation and lipid metabolism. Pre-inhibition of androgen receptor did not influence the inhibition of PPARgamma activity by testosterone. Moreover, pre-treatment with testosterone attenuated the insulin-induced up-regulation of PPARgamma activity. These results provide a novel mechanism for the effect of testosterone on fat mass control.

Abstract
Pancreatic cancer (PC) is an aggressive malignancy with one of the worst outcomes among all cancers. It is the fourth leading cause of cancer death in the United States with a very low five-year survival rate. The high mortality of PC could, in part, be due to their drug resistance characteristics and high propensity for metastasis. Recently, cancer stem cells (CSCs) and epithelial-mesenchymal transition (EMT)-type cells, which shares molecular characteristics with CSCs, have been believed to play critical roles in drug resistance and cancer metastasis as demonstrated in several human malignancies including PC. Thus, the discovery of molecular knowledge of drug resistance and metastasis in relation to CSCs and EMT in PC is becoming an important area of research, and such knowledge is likely to be helpful in the discovery of newer drugs as well as designing novel therapeutic strategies for the treatment of PC with better outcome. In this brief review, we will summarize the current knowledge regarding the CSCs and EMT in the context of drug resistance and metastasis in PC, the molecular events occurring in CSCs and EMT, and the design of novel therapeutic strategies targeting CSCs and EMT-type cells to increase drug sensitivity and suppression of metastasis toward better treatment outcome of patients diagnosed with PC.

Abstract
The objective of this study was to investigate the effects of thalidomide (THD) on interstitial lung fibrosis (ILF). In vitro, human fetal lung fibroblast (HFL-F) to myofibroblast (MF) trans-differentiation was induced by transforming growth factor (TGF)-beta1. The effects of THD on trans-differentiation process or differentiated MF were evaluated by measuring hydroxyproline (HYP) content by alkaline hydrolysis colorimetry, alpha-smooth muscle actin (alpha-SMA) protein by Western blot and alpha-SMA and pro-collagen III mRNA expressions by semi-quantitative reverse transcription-polymerase chain reaction; in vivo, a mouse model of ILF was generated by daily subcutaneous injection of bleomycin (BLM) in female C3H mice. Gastric perfusion of THD began 1 week prior to injection and lasted for 8 weeks. Lung specimens were harvested at different time-points (1, 4, 6 and 8 weeks) for pathology and immunohistochemistry examination. The HYP content, alpha-SMA and pro-collagen III mRNA expressions were also assessed. THD inhibited the up-regulation of HYP protein, pro-collagen III mRNA and alpha-SMA protein induced by TGF-beta1 in HFL-F cells, and additionally inhibited pro-collagen III mRNA expression on trans-differentiated MF. THD reduced HYP synthesis in the lung tissues of BLM-treated mice at week 4, and slightly reduced the numbers of alpha-SMA-positive cells. THD had an effect on ILF models both in vitro and in vivo.
