The Heterotaxy Gene CCDC11 Is Important for Cytokinesis via RhoA Regulation
ABSTRACT Mutations in CCDC11 (cfap53) have been identified in multiple patients with heterotaxy (Htx), a disorder of left–right (LR) patterning of the internal organs. In Xenopus, depletion of Ccdc11 causes defects in LR patterning, recapitulating the patient phenotype. Upon Ccdc11 depletion, monociliated cells of the Left–Right Organizer (LRO) exhibit

TRiC Is a Structural Component of Mammalian Sperm Axonemes
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 ...

TRPV4 is the temperature-sensitive ion channel of human sperm. [PDF]
Ion channels control the ability of human sperm to fertilize the egg by triggering hyperactivated motility, which is regulated by membrane potential, intracellular pH, and cytosolic calcium.

ABSTRACT Cells have an intrinsic ability to rapidly respond to environmental change to regulate cell cycle progression and membrane organisation, thereby affecting cell growth and division. The actin cytoskeleton is a highly dynamic complex of proteins that can rapidly reorganise to change the growth pattern of a cell.

Interaction Between Actin and Microtubules During Plant Development
ABSTRACT The dynamic interaction between actin filaments (AFs) and microtubules (MTs) plays a crucial role in regulating key developmental and physiological processes in plant cells, particularly in the formation of specialized cell types with distinct shapes and functions, such as pollen tubes, trichomes, and leaf epidermal cells.

The NLS3 Motif in TPX2 Regulates Spindle Architecture in Xenopus Egg Extracts
ABSTRACT A bipolar spindle composed of microtubules and many associated proteins functions to segregate chromosomes during cell division in all eukaryotes, yet both spindle size and architecture vary dramatically across different species and cell types.

Banka sperme (ili kriobanka) je način/mogućnost pohrane sperme čovjeka. Spermu potom koriste žene koje žele postići trudnoću i materinstvo. Dva su glavna razloga zašto se muškarci odluče na pohranu (donaciju) sperme: 1) da bi osigurali reproduktivnu sposobnost kada su suočeni s bolešću koja bi mogla biti smrtonosna ili čije bi liječenje moglo ...

PEK14: A Kinesin‐4 Necessary for Male‐Derived Fertility in Arabidopsis thaliana
ABSTRACT Of the 61 kinesins annotated in Arabidopsis thaliana, many are still without assigned function. Here, we have screened an insertional mutant library of Arabidopsis pollen‐expressed kinesins for fertility defects. Insertional mutants for three kinesins showed a significant reduction in seed set.

ABSTRACT Of the three types of cytoskeleton known in animals—actin, microtubules, and intermediate filaments—only actin and microtubules exist in plants. Both play important roles in cellular shaping, organelle movement, organization of the endomembrane system, and cell signaling.

Biology and Management of Male‐Bodied Athletes in Elite Female Sports
Graphical representation of the relationships of transgender and XY DSDF as male‐bodied athletes along the binary dimensions of biological sex. ABSTRACT The physical advantages in elite power sports that allow men to surpass women are derived from the experience of male puberty.
