Spatial genetic structure of in South China.

South China presents an excellent opportunity to build a phylogeographic paradigm for complex geological history, including mountain lifting, climate change, and river capture/reversal events. The phylogeography of cyprinids, particularly , an endemic species restricted to South China, was examined to explore the relationship between the populations in Red River, Hainan Island and its adjacent mainland China. A total of 37 haplotypes were genotyped for the mitochondrial cytochrome (Cyt ) gene in 115 specimens from 11 river systems.

Establishment of a monoclonal antibody for human LXRalpha: Detection of LXRalpha protein expression in human macrophages.

Liver X activated receptor alpha (LXRalpha) forms a functional dimeric nuclear receptor with RXR that regulates the metabolism of several important lipids, including cholesterol and bile acids. As compared with RXR, the LXRalpha protein level in the cell is low and the LXRalpha protein itself is very hard to detect. We have previously reported that the mRNA for LXRalpha is highly expressed in human cultured macrophages.

A novel method for viral display of ER membrane proteins on budded baculovirus.

The baculovirus expression system has been used to express large quantities of various proteins, including membrane receptors. Here, we reveal a novel property of this expression system to be that certain membrane proteins can be displayed on the budded virus itself. We introduced the genes encoding sterol regulatory element-binding protein-2 (SREBP-2) or SREBP cleavage-activating protein (SCAP), important integral membrane proteins of the endoplasmic reticulum (ER) and/or the Golgi apparatus related to cellular cholesterol regulation, into a baculovirus vector.

AIM inhibits apoptosis of T cells and NKT cells in Corynebacterium-induced granuloma formation in mice.

Apoptosis inhibitor expressed by macrophages (AIM) inhibits apoptosis of CD4(+)CD8(+) (CD4/CD8) double-positive thymocytes, and supports the viability of these cells on the thymic selection. However, pleiotropic functions of AIM have been suggested. In this study, heat-killed Corynebacterium parvum (C.

The generation of monoclonal antibodies against human peroxisome proliferator-activated receptors (PPARs).

Monoclonal antibodies (Mabs) are valuable reagents for the purification, characterization and immunolocalization of proteins. In this study, we raised Mabs against human peroxisome proliferator-activated receptors (PPARs) using baculovirus particles displaying surface glycoprotein gp64-fusion proteins as the immunizing agent. In this system, to display fusion proteins on the viral surface, the amino terminal sequences of human PPARd and PPARg2 are inserted in-frame between the signal sequence and the mature domain of the gp64 nucleotide sequence.
