Sperm protein 17 is expressed in the sperm fibrous sheath [PDF]

Journal of Translational Medicine, 2009
Sperm protein 17 (Sp17) is a highly conserved mammalian protein characterized in rabbit, mouse, monkey, baboon, macaque, human testis and spermatozoa. mRNA encoding Sp17 has been detected in a range of murine and human somatic tissues. It was also recognized in two myeloma cell lines and in neoplastic cells from patients with multiple myeloma and ...

Co-evolution of male and female reproductive traits across the Bruchidae (Coleoptera) [PDF]

, 2008
1. Despite the obvious importance of spermatozoa to individual reproductive success a general explanation of variation in spermatozoan form and function is still lacking. In species with internal fertilization, sperm not only have to interact with the

Post‐Translational Modifications in Cilia and Ciliopathies

Advanced Science, EarlyView.
This review synthesizes current understanding of post‐translational modifications (PTMs) in ciliary proteins and emphasizes their roles in ciliary formation, homeostasis, and signaling. This review also discusses the implication of PTM dysregulation in ciliopathies and explores therapeutic strategies targeting PTM‐modifying enzymes.

Cryopreservation of Pike Perch Sperm in Hatchery Conditions [PDF]

, 2008
Experiments were carried out on pike perch (Sander lucioperca L.) to find a method for stripping sperm without contamination by urine, to determine sperm concentration, and to fertilize large batches of eggs with cryopreserved sperm.

Chromosome‐Level Genome Assembly of the Leafcutter Bee Megachile rotundata Reveals Its Ecological Adaptation and Pollination Biology

Advanced Science, EarlyView.
The genome of Megachile rotundata, an extensively managed solitary pollination bee species, has been sequenced, covering 280.68 Mb and predicting 10 701 genes. The study reveals significant expansions of the Toll gene family and their abundant expression in diapause prepupae, highlighting enhanced immune responses during diapause. This genome serves as

A genetic variant of the sperm-specific SLO3 K+ channel has altered pH and Ca2+ sensitivities [PDF]

, 2017
To fertilize an oocyte, sperm must first undergo capacitation in which the sperm plasma membrane becomes hyperpolarized via activation of potassium (K(+)) channels and resultant K(+) efflux.

Use of sperm DNA fragmentation testing and testicular sperm for intracytoplasmic sperm injection [PDF]

Translational Andrology and Urology, 2017
Dr. Ahmad, in his well-written commentary (1), shared his viewpoints about the utility of sperm DNA fragmentation (SDF) testing on each clinical scenario proposed in the practice recommendations by Agarwal et al . (2). He highlighted the pitfalls of relying on quantitative semen parameters in current practice and the need for a more reliable ...

QSOX2‐Mediated Disulfide Bond Modification Enhances Tumor Stemness and Chemoresistance by Activating TSC2/mTOR/c‐Myc Feedback Loop in Esophageal Squamous Cell Carcinoma

Advanced Science, EarlyView.
High QSOX2 enhances stemness, drug resistance, and metastasis of ESCC cells. QSOX2‐mediated disulfide bond modification activates mTOR/c‐Myc signaling. CAFs‐secreted IGF‐1 drives mTOR/c‐Myc/QSOX2 positive feedback loop. Combining Ebselen, rapamycin, and cisplatin induces tumor dormancy in mice.

REVIEW: Current Status of Extenders and Cryoprotectants on Fish Spermatozoa Cryopreservation [PDF]

, 2005
An important component of many studies of cryopreservation of fish spermatozoa is the type of extenders and cryoprotectants. The suitability of extenders and cryoprotectants differs from one fish to another.
