Excessive androgen levels can severely affect female health. However, most existing models of androgen excess rely on exogenous androgen administration, which does not fully capture the effect of elevated local ovarian testosterone on reproductive and metabolic functions. Here, we report the development of a novel hyperandrogenic mouse model, Cyp17TM-625, generated by combining CRISPR-Cas9 and a Tet-On doxycycline system to induce Cyp17A1 overexpression in ovarian theca-interstitial cells. As a result, Cyp17TM-625 mice exhibited significantly elevated Cyp17A1 messenger RNA and protein levels, accompanied by increased testosterone concentrations without alterations in basal levels of estradiol, progesterone, luteinizing hormone, or follicle-stimulating hormone. These mice …

A Generalized Epilepsy Network Derived From Brain Abnormalities And Deep Brain Stimulation, Gong-Jun Ji, Nico U F Dosenbach, Et Al.

2020-Current year OA Pubs

Idiopathic generalized epilepsy (IGE) is a brain network disease, but the location of this network and its relevance for treatment remain unclear. We combine the locations of brain abnormalities in IGE (131 coordinates from 21 studies) with the human connectome to identify an IGE network. We validate this network by showing alignment with structural brain abnormalities previously identified in IGE and brain areas activated by generalized epileptiform discharges in simultaneous electroencephalogram-functional magnetic resonance imaging. The topography of the IGE network aligns with brain networks involved in motor control and loss of consciousness consistent with generalized seizure semiology. To investigate therapeutic …

While the Woven EndoBridge (WEB) device has transformed the treatment of wide-neck intracranial aneurysms, incomplete occlusion remains a significant challenge requiring better understanding of contributing factors. A retrospective analysis was conducted on multicenter data from patients who underwent WEB device treatment for intracranial aneurysms between January 2011 and December 2022. Using machine learning models, Cox regression, and time-stratified analyses, we evaluated factors associated with persistent incomplete occlusion, defined as non-improving Raymond-Roy Occlusion Classification grade 2 or 3 at final follow-up. Among 813 patients (607 with <  24 months follow-up, 206 with ≥ 24 months), machine learning analysis identified aneurysm height, Acom location, neck diameter, and pretreatment mRS as predictors of persistent incomplete occlusion. On Cox regression. larger aneurysm neck diameter (HR 1.13, 95% CI 1.01-1.27, p = 0.027) and height (HR 1.14, 95% CI 1.02-1.26, p = 0.017), and radial access (HR 2.68, 95% CI 1.76-4.07, p <  0.001) increased, while posterior circulation location (HR 0.56, 95% CI 0.37-0.84, p = 0.005) decreased the risk of persistent incomplete occlusion. Time-stratified analysis revealed that in short-term follow-up (<  24 months), larger aneurysm neck diameter (OR 1.28, 95% CI 1.08-1.52, p = 0.004) increased the risk of incomplete occlusion. In long-term follow-up (≥ 24 months), smoking (OR 2.69, 95% CI 1.04-7.00, p = 0.04), higher pre-treatment mRS (OR 1.78, 95% CI 1.15-2.76, p = 0.009), and immediate flow stagnation (OR 0.33, 95% CI 0.11-0.96, p = 0.04) increased, while older age (OR 0.94, 95% CI 0.90-0.98, p = 0.002) and WEB-DL (OR 0.06, p <  0.001) and SLS devices (OR 0.02, p = 0.003) decreased the risk of persistent incomplete occlusion. Aneurysm characteristics and device type significantly influence long-term WEB treatment outcomes.

S. Anton, Kamran Atabai, Dean Sheppard, Oleg Butovsky, Thomas Arnold

Department of Medicine Faculty Papers

Microglial diversity arises from the interplay between inherent genetic programs and external environmental signals. However, the mechanisms by which these processes develop and interact within the growing brain are not yet fully understood. Here, we show that radial glia-expressed integrin beta 8 (ITGB8) activates microglia-expressed TGFβ1 to drive microglial development. Domain-restricted deletion of Itgb8 in these progenitors results in regionally restricted and developmentally arrested microglia that persist into adulthood. In the absence of autocrine TGFβ1 signaling, microglia adopt a similar phenotype, leading to neuromotor symptoms almost identical to Itgb8 mutant mice. In contrast, microglia lacking the canonical TGFβ signal transducers …

What Single-Cell Rna Sequencing Taught Us About Mgmt Expression In Glioblastoma, Iyad Alnahhas, Mehak Majid Khan, Wenyin Shi

Department of Neurology Faculty Papers

Background.

The promoter methylation status of O-6-methylguanine-DNA methyltransferase (MGMTp) is an important prognostic marker in GBM. Previous studies showed that the expression of MGMT based on immunohistochemistry did not correlate with survival. This is partly because nontumor cells express MGMT. Single-cell sequencing assesses gene expression in tumor cells specifically.

Methods.

We used publicly available data from 3 recent single-cell/nucleus sequencing GBM studies that included MGMTp methylation status data for patients to evaluate MGMT expression at the single-cell level.

Results.

In the CPTAC study, a median of 0.82% and 5.7% of tumor cells expressed MGMT in the …
