Compared to healthy controls, microRNA-29c (miR-29c) is highly expressed in the heart during progression towards ventricular septal defect. However, studies on miR-29c function in heart development are scarce. We investigated the role of miR-29c in P19 cell proliferation, apoptosis, and differentiation and the underlying mechanisms. We evaluated proliferation and cell cycle progression, detected morphological...
Trehalose represents the main hemolymph sugar in many insects, and it functions in energy metabolism and protection in extreme environmental conditions. To gain an insight into trehalose functions in Delia antiqua diapausing pupae, genes encoding trehalose-6-phosphate synthase (TPS), trehalose-6-phosphatase (TPP) and trehalase (TRE) were identified and characterized. Analysis of the deduced amino...
To fully explore the trends of atomic composition during the macroevolution from prokaryote to eukaryote, five atoms (oxygen, sulfur, nitrogen, carbon, hydrogen) and related functional groups in prokaryotic and eukaryotic proteins were surveyed and compared. Genome-wide analysis showed that eukaryotic proteins have more oxygen, sulfur and nitrogen atoms than prokaryotes do. Clusters of Orthologous...
Nuclear receptor (NR) dependent transcriptional action requires recruitment of diverse factors characterized as coregulators. PNRC (proline-rich nuclear receptor coregulatory protein) is a member of coregulators that are capable of potentiating the transcriptional activity of NRs. Here we identified three human PNRC splicing variants designated PNRC1c, PNRC1d and PNRC1f. PNRC1c and PNRC1f are generated...
The farnesoid X receptor (FXR) is a bile acid (BA)-activated nuclear receptor that plays a major role in the regulation of BA and lipid metabolism. Although modulation of FXR expression has been reported, the mechanisms underlying the regulation of human FXR are yet unclear. Functional assays showed that the −150/+29 nucleotides region from the first nucleotide at the Exon I is the minimal promoter...
Diapause prepares insects and other arthropods to survive in harsh environments. To explore the molecular basis of winter (WD) and summer diapauses (SD), we screened for diapause-specific genes in the onion maggot, Delia antiqua, that diapauses as a pupa in both summer and winter. A diapause-induced transcript, DaTrypsin, was identified through differential display, and examined by Northern blot,...
Tissue-specific expression of parental K-ras allele(s) was investigated by single-strand conformation polymorphism analysis of the 3′ untranslated region of the K-ras gene in normal lung, spleen, liver and kidney from (A/J×TSG-p53) F 1 mice. The expression of A/J K-ras allele was equal to that of C57BL/6J allele in normal spleen, liver and kidney. However, transcripts from A/J K-ras allele...
