The current state of knowledge concerning the expression of the nuclear genes that code the light-harvesting chlorophyll a/b-binding polypeptides of photosystem II is presented. This review covers the structure of these genes, the complex multistep pathway involved in their expression, and the environmental and other factors which regulate their expression.(More)
PURPOSE Circulating endothelial cells (CEC) have been widely used as a prognostic biomarker and regarded as a promising strategy for monitoring the response to treatment in several cancers. However, the presence and biologic roles of CECs have remained controversial for decades because technical standards for the identification and quantification of CECs(More)
Angiogenesis is crucial for tumor growth and metastasis. Blocking this process is, therefore, a potentially powerful approach for the treatment of cancer. Human apolipoprotein(a) kringle V (rhLK8) is an angiogenesis inhibitor and is currently under development as an anti-cancer therapeutic. However, a relatively short in vivo half-life limits its widespread(More)
The effects of progesterone on the acrosome reaction, as well as the effects of RU486 on the progesterone-induced acrosome reaction in capacitated boar spermatozoa, were investigated. Progesterone, a major steroid that is secreted by the cumulus cells of oocyte, clearly induced the acrosome reaction in a dose-dependent manner in capacitated boar(More)

The purified 32 kDa boar sperm protease, known as the 32 kDa sperminogen, was identified by reverse transcription polymerase chain reaction (RT-PCR) and Northern blot analysis following its partial peptide sequencing. The 32 kDa boar sperm protease was purified from the acid extracts of boar spermatozoa and subjected to CNBr-digestion. The most prominently(More)
INTRODUCTION The present study compared the effect of combination therapy using human apolipoprotein(a) kringle V (rhLK8) to conventional chemotherapy with paclitaxel for human ovarian carcinoma producing high or low levels of vascular endothelial growth factor (VEGF). MATERIALS AND METHODS Human ovarian carcinoma cells producing high (SKOV3ip1) or low(More)
A putative non-genomic progesterone receptor was identified by Western blot analysis from the membrane fraction but not the cytosolic fraction of boar spermatozoa using monoclonal antibody (mAb) C-262. When the membrane and the cytosolic fractions of boar liver, kidney, uterus and spermatozoa were analyzed with mAb C-262, protein bands with molecular masses(More)
Mammalian spermatozoa and their various proteins undergo various modifications during maturation in the epididymis. To characterize proteins that change in quantity during this maturational process, boar spermatozoa were collected from various regions of the epididymis, and extracts were analyzed by two-dimensional gel electrophoresis (2-DE). A number of(More)
p57kip2, a KIP family cyclin-dependent kinase (Cdk) inhibitor, blocks the cell cycle by acting on multiple cyclin-Cdk complexes. To investigate the role of p57kip2 in human fertility, the expression of p57kip2 was investigated in testes from normal and obstructive azoospermic male patients who were positive for p57kip2 mRNA. In the seminiferous tubule,(More)
