INhibitor of Growth (ING1-5) proteins are epigenetic readers that target histone acetyltransferase (HAT) or histone deacetylase (HDAC) complexes to the H3K4Me3 mark of active transcription. ING5 targets Moz/Morf and HBO1 HAT complexes that alter acetylation of H3 and H4 core histones, affecting gene expression. Previous experiments in vitro indicated that ING5 functions to maintain stem cell character in normal and in cancer stem cells.

The surgical procedure detailed in this case report focuses on the treatment of a large cardiac hydatid cyst located in the intraventricular septum. The surgical intervention comprised a comprehensive approach involving a median sternotomy and cardiopulmonary bypass. A localized mass below the tricuspid valve at the basal region of the interventricular septum was revealed.

However, while PVS is also prevalent amongst Vascular Dementia (VD), the pathological distinctions between regional PVS in AD- and VD-driven cohorts remain largely unknown. Through a mixed dementia cohort, we examined these pathology-driven localization patterns via automated PVS segmentations from T2-weighted MRI.

However, the association of LATE-NC with brain morphometry has not been thoroughly investigated. In this work, we examined the association of LATE-NC with brain morphometric anomalies using deformation-based morphometry (DBM) in a large community cohort of older adults that came to autopsy (N=897).

Context: The growth hormone (GH) secretagogue receptor, encoded by GHSR, is expressed on somatotrophs of the pituitary gland. Stimulation with its ligand ghrelin, as well as its constitutive activity, enhances GH secretion. Studies in knock-out mice suggest that heterozygous loss-of-function of GHSR is associated with decreased GH response to fasting, but patient observations in small case reports have been equivocal.
