KLC3 is involved in sperm tail midpiece formation and sperm function

Developmental Biology, 2012
Kinesin light chain 3 (KLC3) is the only known kinesin light chain expressed in post-meiotic male germ cells. We have reported that in rat spermatids KLC3 associates with outer dense fibers and mitochondrial sheath. KLC3 is able to bind to mitochondria in vitro and in vivo employing the conserved tetratrico-peptide repeat kinesin light chain motif. The

Environmental exposure to non-persistent endocrine disrupting chemicals and semen quality: An overview of the current epidemiological evidence

International Journal of Occupational Medicine and Environmental Health, 2018
Some of the recent publications have reported a decline in semen quality in the last few decades. This phenomenon is associated with environmental factors, particularly with exposure to endocrine disrupting chemicals (EDCs).

Evaluation of SEPT2 and SEPT4 transcript contents in spermatozoa from men with asthenozoospermia and teratozoospermia

Health Science Reports, 2021
Background and aims Motility and morphological defects of spermatozoa can cause male infertility. Sperm RNAs are related to sperm quality. They are considered to have clinical values as a biomarker for assessing sperm quality and fertility potential. The

Formation of Detached Tail and Coiled Tail of Sperm in a Beagle Dog

Journal of Veterinary Medical Science, 2005
The right testis and epididymis were excised from a Beagle dog that ejaculated high percentages of sperm with detached tails and with coiled tails. Cross sections of the organs were stamped on glass slides and histological examination of the organs was performed to find the portion where sperm with the abnormal tails appear. Many sperm with tails whose

Isolation and Characterization of a Rabbit Sperm Tail Protein [PDF]

Archives of Andrology, 1986
Rabbit sperm tails were obtained by a nitrogen cavitation procedure and separated by discontinuous sucrose gradient centrifugation. Proteins were extracted from sperm tails with 3[(3-cholamidopropyl)-dimethylammonio]-1-propane sulfonate (CHAPS) and separative disk electrophoresis and DEAE-trisacryl column chromatography. A protein with an estimated mol

Glutathione S-transferase Mu 3 is associated to in vivo fertility, but not sperm quality, in bovine

Animal, 2022
In the dairy breeding industry, pregnancy of dairy cows is essential to initiate milk production, so that high fertility rates are required to increase their productivity.

Dark side of the epididymis: tails of sperm maturation [PDF]

Andrology, 2019
AbstractBackgroundThe Hermes body (HB) previously called the cytoplasmic droplet is a focal distension of the flagellar cytoplasm of epididymal spermatozoa consisting mainly of isolated flattened Golgi cisternae.ObjectiveTo define a functional role for the HB of epididymal spermatozoa.MethodsIsolated fractions of HBs of epididymal spermatozoa were ...

Purification and preparation of Marchantia polymorpha Auxin Response Factor 2 for phase separation studies

FEBS Open Bio, EarlyView.
We describe detailed protocols for the purification and preparation of Marchantia polymorpha Auxin Response Factor 2 (MpARF2). This protein is fused to an MBP solubility tag and an mNG fluorescent tag and is purified from Escherichia coli. The presented procedures make it possible to study MpARF2 assemblies, which could arise from phase separation ...
