Luteinizing hormone receptor knockout mouse: What has it taught us?
Abstract Luteinizing hormone (LH), along with its agonist choriongonadotropin (hCG) in humans, is the key hormone responsible for the tropic regulation of the gonadal function. LH and hCG act through their cognate receptor, the luteinizing hormone/choriongonadotropin receptor (LHCGR; more appropriately LHR in rodents lacking CG), located in the testis ...

Background Mating changes the mechanism by which E2 regulates oviductal egg transport, from a non-genomic to a genomic mode. Previously, we found that E2 increased the expression of several genes in the oviduct of mated rats, but not in unmated rats ...

Natural History of the Common Sooty Wing Skipper, \u3ci\u3ePholisora Catullus\u3c/i\u3e (Lepidoptera: Hesperiidae), in Central Illinois [PDF]
The common sooty wing skipper, Pholisora catullus, has three broods each year in east-central Illinois. Adults are active for only a few hours at mid-day_ Wing color is a rough indicator of age in the field, changing from black to brown over 5 days ...

The role of mating in oviduct biology
SUMMARYThe oviduct connects the ovary to the uterus, and is subject to changes that influence gamete transport, fertilization, and early embryo development. The ovarian steroids estradiol and progesterone are largely responsible for regulating oviduct function, although mating signals also affect the female reproductive tract, both indirectly, through ...

The absence of both RIBC1 and RIBC2 induces decreased sperm motility and litter size in male mice
Abstract Background RIBC1 (RIB43A domain with coiled‐coils 1) and RIBC2 (RIB43A domain with coiled‐coils 2) are homolog proteins of RIB43a which is localized to microtubules in the cilia and flagella of unicellular organisms. Cryo‐electron microscopy and artificial intelligence studies showed that RIBC1 and RIBC2 are microtubule inner proteins (MIPs ...

A COMPARATIVE MICROMETRY AND HISTOCHEMICAL STUDY ON THE OVIDUCT OF WHITE LEG HORN AND RHODE ISLAND RED CHICKEN [PDF]
The present work was conducted on oviduct of 20 weeks old White leg horn (WLH) and Rhode Island Red (RIR) chickens to observe and compare the micrometrical variation and histochemical reaction of the oviduct segments between WLH and RIR breeds of ...

National Institute of Allergy and Infectious Diseases workshop report: "Chlamydia vaccines: The way forward". [PDF]
Chlamydia trachomatis (Ct), an intracellular pathogen, is the most common bacterial sexually transmitted infection. In addition to acute cervicitis and urethritis, Ct can lead to serious sequelae of significant public health burden including pelvic ...

Cryptorchidism: Novel genetic insights into CCDC149 mutations
Abstract Background Cryptorchidism, characterized by the failure of one or both testes to descend into the scrotum, is a common congenital condition that can lead to infertility and increased risk of testicular cancer. CCDC149, a coiled‐coil domain‐containing protein, has been implicated in various developmental processes, but its role in the male ...

Screening of reliable reference genes for the normalization of RT-qPCR in chicken oviduct tract
: Utilizing publicly available RNA-seq data to screen for ideal reference genes is more efficient and accurate than traditional methods. Previous studies have identified optimal reference genes in various chicken tissues, but none have specifically ...
