AMPylation is a post-translational modification involving the transfer of adenosine monophosphate (AMP) from adenosine triphosphate (ATP) to target proteins, serving as a critical regulatory mechanism in cellular functions. This study aimed to expand the phenotypic spectrum associated with mutations in the FICD gene, which encodes an adenyltransferase enzyme involved in both AMPylation and deAMPylation. A clinical evaluation was conducted on a patient presenting with a complex clinical profile.

The "Cell Cycle Hypothesis" suggests that the abnormal re-entry of neurons into the cell division cycle leads to neurodegeneration, a mechanism supported by in vitro studies on neuronal-like cells treated with the hyperphosphorylating agent forskolin. Pterostilbene, a bioavailable compound found in foods such as blueberries and grapes, may exert neuroprotective effects and could serve as a potential adjunct therapy for neurodegenerative diseases. .

Objective: The purpose of this study was to describe the developmental patterns of the posterior sloping angle (PSA) of the proximal femoral epiphyseal growth plate (PFEP) in a cohort of healthy Chinese children aged 5 to 14 years.

Methods: Pelvic frog-leg lateral radiographs of 400 healthy children (n=800 hips) were retrospectively analyzed. The cohort included 215 males and 185 females with a mean age of 9.

Ninjurin-1 (NINJ1), initially identified as a stress-induced protein in neurons, recently emerged as a key mediator of plasma membrane rupture (PMR) during apoptosis, necrosis, and pyroptosis. However, its involvement in ferroptosis is less well elucidated. Here, we demonstrate that NINJ1 also plays a crucial role in ferroptosis, but through a distinct mechanism.

Protein phosphatase 2A (PP2A) is a family of multifunctional enzymatic complexes crucial for cellular signalling, playing a pivotal role in brain function and development. Mutations in specific genes encoding PP2A complexes have been associated with neurodevelopmental disorders with hypotonia and high risk of seizures. In the current work, we present an individual with specific learning problems, motor coordination disorders, hypotonia and behavioural issues.
