TRiC Is a Structural Component of Mammalian Sperm Axonemes

Cytoskeleton, EarlyView.
ABSTRACT The TRiC chaperonin is responsible for folding ~5%–10% of the proteome in eukaryotic cells. Our recent cryo‐electron microscopy studies of axonemes from diverse mammalian cell types led to the surprising discovery that a fully assembled TRiC chaperonin is a structural component of mammalian sperm flagella, where it is tethered to the radial ...

Actin in Human Spermatozoa [PDF]

Biology of Reproduction, 1982
An actin-like material was extracted from human spermatozoa. The material comigrated with actin on sodium dodecylsulfate (SDS) polyacrylamide gel electrophoresis, and showed specific affinity for myosin. Purified anti-actin antibodies were used to localize actin to the posterior region of the sperm head and to the connecting piece, midpiece and ...

A role of the uterine cervix in the pathogenesis of adenomyosis and endometriosis?

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Data indicate a link between the cervix and pathologies like adenomyosis and endometriosis. Uterine flexion on the cervix, diameter and stiffness of the internal cervical orifice represent an obstacle to downstream menstrual flow, that when excessive increases the intensity of uterine contractions.
