Androgen‐Induced Prostate‐Specific Antigen Gene Expression Is Mediated via Dihydrotestosterone in LNCaP CellsWiley - Tập 24 Số 5 - Trang 681-687 - 2003

ABSTRACT: Prostate cancer is a leading cause of cancer death in American males. Androgens play an essential role in prostate development, growth and pathogenesis of benign prostate hyperplasia, and prostate cancer. Although testosterone is the main androgen secreted from the testes, dihydrotestosterone (DHT), a more potent androgen converted from testosterone by 5α‐...... hiện toàn bộ
Relationship of Spermatozoal Migration in Cervical Mucus to Bovine FertilityWiley - Tập 2 Số 2 - Trang 103-107 - 1981
Hans L. Kummerfeld, Steven P. Lorton, R.H. Foote
Frozen bovine semen from males of wellestablished, generally high fertility levels was thawed and used in three experiments for In vitro capillary tube migration through cervical mucus. Bovine cervical mucus from individual heifers or a group of heifers was evaluated in these assays. Correlations between spermatozoal migration and bull fertility were small and no...... hiện toàn bộ
Oxidative Stress: A Common Factor in Testicular DysfunctionWiley - Tập 29 Số 5 - Trang 488-498 - 2008
Terry T. Turner, Jeffrey J. Lysiak
ABSTRACT:Oxidative stress results from the production of oxygen radicals in excess of the antioxidant capacity of the stressed tissue. Many conditions or events associated with male infertility are inducers of oxidative stress. X‐irradiation, for example, or exposure to environmental toxicants and the physical conditions of varicocele and cryptorchidism have been dem...... hiện toàn bộ
The Action of Calcitonin on the TM4 Sertoli Cell Line and on Rat Sertoli Cell‐Enriched CulturesWiley - Tập 10 Số 4 - Trang 321-331 - 1989
Atif M. Nakhla, Jennie P. Mather, Olli A. Jänne, C. Wayne Bardin
The effects of synthetic salmon calcitonin on primary Sertoli cell‐enriched cultures and on an established cell line (TM4 cells, derived from immature mouse Sertoli cells) were studied. Synthetic salmon calcitonin stimulated the conversion of [3H]adenine to [3H]cyclic AMP in both cell systems. In addition, this peptide stimulat...... hiện toàn bộ
A Simple, Clinical Assay to Evaluate The Acrosin Activity of Human SpermatozoaWiley - Tập 10 Số 3 - Trang 221-231 - 1989

Acrosin, a sperm‐specific arosomal proteinase, has an essential role in the fertilization process. Low levels of acrosin appear to be associated with subfertility and infertility, and the acrosin activity of spermatozoa may potentially be a useful indicator of semen quality. The standard acrosin tests employed by research laboratories are too complicated and/or time consuming for clinical ...... hiện toàn bộ
The Actions of Calcitonin on the TM3 Leydig Cell Line and on Rat Leydig Cell‐Enriched CulturesWiley - Tập 10 Số 4 - Trang 311-320 - 1989
Atif M. Nakhla, C. Wayne Bardin, Yoram Salomon, Jennie P. Mather, Olli A. Jänne
Studies demonstrating calcitonin receptors on Leydig cells have suggested that these cells may be one of the many sites affected by this peptide. To investigate this possibility, the effect of synthetic salmon calcitonin on the TM3 Leydig cell line (derived from immature mouse Leydig cells) and on primary Leydig cell‐enriched preparations was examined. Synthetic salmon...... hiện toàn bộ
