In utero electroporation allows for rapid gene delivery in a spatially- and temporally-controlled manner in the developing central nervous system (CNS). Here we describe a highly adaptable in utero electroporation protocol that can be used to deliver expression constructs into multiple embryonic CNS domains, including the telencephalon, diencephalon and retina.

Human Y-chromosomal binary polymorphisms have been considered to preserve the paternal genetic legacy and provide evidence on human evolution and the genetic relationships among and demographic history of different populations. To reveal the genetic origin and immigration of the Fujian Han, 13 binary markers on the Y chromosome were used to screen Fujian Han by allele-specific polymerase chain reaction. The results indicated that the M9G marker was highly prevalent (96.20%), suggesting a significant genetic drift. In addition, M122C frequency was only 22.78%, and M45A and M103T were default. The distinctive haplogroup frequencies (H1, H5, and H6/7/8) imply that the haplogroup pattern is a relatively ancestral and interim type.

Burkholderia cenocepacia is an opportunistic pathogen that can cause serious infections in cystic fibrosis (CF) patients. The ET12 lineage appears particularly virulent in CF; however, its pathogenesis is poorly understood and may be associated with host response. To help characterize this response, the ability of B. cenocepacia to induce cytotoxicity and apoptosis in an epithelial cell model was examined. Upon infection with B. cenocepacia strain K56-2, A549 human lung epithelial cells underwent significant cell death; propidium iodine staining and DNA fragmentation assays suggested apoptosis. Initiation of cell death was independent of the type III secretion system, biofilm formation, and secreted bacterial cytotoxins. However, the frequency of cell death was lower in cells infected with a non-piliated mutant, K56-2 cblA::Tp. Furthermore, purified cbl pili were found to directly induce cytotoxicity in A549 cells and activate caspase-9, -8, -7, and -3, the major cysteine proteinases involved in apoptosis. It appears that B. cenocepacia cbl pili, which are a distinctive feature of the ET12 lineage, act as an initiator of cytotoxicity and apoptosis. Understanding the role of cbl pili in the pathogenesis of B. cenocepacia infections offers the potential for decreasing the virulence of these potentially life-threatening organisms in CF patients.
