Objective Selection of sperm for intra-cytoplasmic sperm injection (ICSI) is usually considered as the ultimate technique to alleviate male-factor infertility. In routine ICSI, selection is based on morphology and viability which does not necessarily preclude the chance injection of DNA-damaged or apoptotic sperm into the oocyte. Sperm with high negative surface electrical charge, named “Zeta p...

Herpesviruses have mainly co-evolved with their hosts for millions of years. Consequently, different related host species may have been infected by various genetically related herpesviruses. Illustrating this concept, several ruminant alphaherpesviruses have been shown to form a cluster of viruses closely related to bovine herpesvirus 1 (BoHV-1): namely bovine herpesvirus 5, bubaline herpesviru...

This study aims to investigate the role of Rho-kinase in phenotype switching and proliferation of bovine tracheal smooth muscle. To induce different phenotypic states, bovine tracheal smooth muscle strips were cultured (8 days) in 10% foetal bovine serum (foetal bovine serum, less contractile phenotype) or insulin (1 microM, hypercontractile phenotype) and compared to strips cultured in serum-f...

The complete genome sequence of bovine papillomavirus 2 (BPV2) from Brazilian Amazon Region was determined using multiple-primed rolling circle amplification followed by Illumina sequencing. The genome is 7,947 bp long, with 45.9% GC content. It encodes seven early (E1, E2,E4, E5, E6,E7, and E8) and two late (L1 and L2) genes. The complete genome of a BPV2 can help in future studies since this ...

ATP-binding cassette transporter G2 (ABCG2) is involved in the secretion of several compounds milk. The vitro and vivo interactions between tryptophan-related ABCG2 were investigated. tryptophan metabolome was determined by liquid chromatography-tandem mass spectrometry milk plasma from wild-type Abcg2?/? mice as well dairy cows carrying Y581S polymorphism (Y/S) noncarrier animals (Y/Y). milk-t...

erbB-2 amplification and overexpression have been suggested as potentially useful prognostic markers in bladder cancer. We examined 141 bladder tumor specimens (45 fresh tissue samples and 96 formalin fixed tissue blocks) for erbB-2 amplification using fluorescence in situ hybridization. A dual labeling hybridization using a repetitive pericentromeric probe specific for chromosome 17 and a cosm...

Abnormalities of chromosome 17 are important molecular genetic events in human breast cancers. Several famous oncogenes (HER2, TOP2A and TAU), tumor suppressor genes (p53, BRCA1 and HIC-1) or DNA double-strand break repair gene (RDM1) are located on chromosome 17. We searched the literature on HER2, TOP2A, TAU, RDM1, p53, BRCA1 and HIC-1 on the Pubmed database. The association of genes with chr...
