TRPV4 is the temperature-sensitive ion channel of human sperm
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.

Hyperactivated endolysosomal trafficking in melanoma
Cutaneous melanoma is an increasingly frequent solid tumor that accounts for 80% of skin cancer-related deaths. Characterized by a complex and heterogeneous genetic background and a notorious functional plasticity, melanoma has shifted from a “black box” to a paradigm of how basic research can be successfully translated into significant improvements of

Amygdala hyperactivation in untreated depressed individuals [PDF]
The amygdala participates in the detection and control of affective states, and has been proposed to be a site of dysfunction in affective disorders. To assess amygdala processing in individuals with unipolar depression, we applied a functional MRI (fMRI) paradigm previously shown to be sensitive to amygdala function.

The Chemosensing Role of CatSper in Mammalian Sperm: An Updated Review
After sperm enter the female reproductive tract, the physicochemical and biochemical microenvironment undergoes significant changes. In particular, the large changes in various ions encountered by sperm may alter the physiology of sperm, ultimately ...

Hyperactivation in human semen and sperm subpopulations by selected calcium modulators [PDF]
Magister Scientiae (Medical Bioscience) - MSc(MBS)A functional sperm is critical for successful fertilization in order to deliver an intact genome to the site of fertilization. It is often characterized by high motility and normal morphology.

PKR deficiency delays vascular aging via inhibiting GSDMD-mediated endothelial cell hyperactivation
Summary: Vascular aging is an independent risk factor for cardiovascular diseases, but the regulatory mechanism is not clearly understood. In this study, we found that endothelial PKR activity is elevated in aging aorta tissues, which is accompanied with

P-REX1-Independent, Calcium-Dependent RAC1 Hyperactivation in Prostate Cancer [PDF]
The GTPase Rac1 is a well-established master regulator of cell motility and invasiveness contributing to cancer metastasis. Dysregulation of the Rac1 signaling pathway, resulting in elevated motile and invasive potential, has been reported in multiple ...
