Norepinephrine Induces Sertoli Cell Ferroptosis via Receptors Desensitization Causing Stress‐Related Male Reproductive Dysfunction

open access: yesAdvanced Science, EarlyView.
Psychological stress activates the sympathetic–adrenal axis, elevating norepinephrine (NE) and suppressing reproductive hormones, thereby impairing male reproduction. Excess NE overactivates and desensitizes β‐adrenergic receptors (β‐ARs), triggering Sertoli cell ferroptosis and disrupting spermatogenesis.

A systematic review of p53 regulation of oxidative stress in skeletal muscle

open access: yesRedox Report, 2018
Background: p53 is a tumor suppressor protein involved in regulating a wide array of signaling pathways. The role of p53 in the cell is determined by the type of imposed oxidative stress, its intensity and duration.

Transcriptome changes and cAMP oscillations in an archaeal cell cycle [PDF]

open access: yes, 2007
Background The cell cycle of all organisms includes mass increase by a factor of two, replication of the genetic material, segregation of the genome to different parts of the cell, and cell division into two daughter cells.

SIRT6 Lysine‐Demyristoylates ATF2 to Ameliorate Vascular Injury via PRKCD/VE‐Cadherin Pathway Regulating Vascular Endothelial Barrier

open access: yesAdvanced Science, EarlyView.
A novel modified SIRT6 variant (dSIRT6) H133Y‐mediated enrichment technique unmasks 15 new human lysine‐myristoylated proteins. Notably, Sirtuin 6 (SIRT6) demyristoylation of activating transcription factor 2 (ATF2) at K296 orchestrates its nucleoplasmic translocation.

Anchored phosphatases modulate glucose homeostasis. [PDF]

open access: yes, 2012
Endocrine release of insulin principally controls glucose homeostasis. Nutrient-induced exocytosis of insulin granules from pancreatic β-cells involves ion channels and mobilization of Ca(2+) and cyclic AMP (cAMP) signalling pathways.

Mechanical Cues Regulate Cargo Sorting and Export at the Golgi

open access: yesAdvanced Science, EarlyView.
A pathway is identified linking extracellular matrix stiffness to secretion via Src–FAK–AMPK–GBF1 signaling. Golgi‐localized GBF1 acts as a mechanotransducer whose phosphorylation controls post‐Golgi cargo sorting toward secretion or lysosomal degradation.

Purification and characterization of a calmodulin-dependent protein kinase that is highly concentrated in brain [PDF]

open access: yes, 1983
A calcium and calmodulin-dependent protein kinase has been purified from rat brain. It was monitored during the purification by its ability to phosphorylate the synaptic vesicle-associated protein, synapsin I.

Rapamycin induces transactivation of the EGFR and increases cell survival. [PDF]

open access: yes, 2009
The mammalian target of rapamycin (mTOR) signaling network regulates cell growth, proliferation and cell survival. Deregulated activation of this pathway is a common event in diverse human diseases such as cancers, cardiac hypertrophy, vascular ...

Adenylosuccinate Synthase 1 Deficiency Improves Energy Metabolism by Promoting Adipose Tissue Re‐esterification via Glycerol Kinase Upregulation

open access: yesAdvanced Science, EarlyView.
Working model of Adss1‐mediated regulation of energy metabolism in adipose tissue. In beige adipocytes, Adss1 interacts with HDAC3 in the cytoplasm, and its loss reduces nuclear HDAC3 while increasing cytosolic fractions. This redistribution suppresses HDAC activity and enhances H3K27 acetylation at the Gk promoter, leading to transcriptional ...

Disruption of Gut Microbiota‐Mediated De Novo NAD+ Synthesis Contributes to the Development of Polycystic Ovary Syndrome

open access: yesAdvanced Science, EarlyView.
This study demonstrates that patients with PCOS exhibit altered gut microbial profiles, and FMT from PCOS patients induces PCOS‐like symptoms in mice. Specifically, gut dysbiosis reduces 3‐HAA levels in the context of PCOS. Administration of 3‐HAA to mice alleviates PCOS by promoting de novo NAD+ synthesis.
