Upregulation of Cyclin E1 and subsequent activation of CDK2 accelerates cell cycle progression from G1 to S phase and is a common oncogenic driver in gynecological malignancies. WEE1 kinase counteracts the effects of Cyclin E1/CDK2 activation by regulating multiple cell cycle checkpoints. Here we characterized the relationship between Cyclin E1/CDK2 activation and sensitivity to the selective WEE1 inhibitor azenosertib.

Objectives: Maternal obesity increases a child's risk of neurodevelopmental impairment. However, little is known about the impact of maternal obesity on fetal brain development.
Methods: We prospectively recruited 20 healthy pregnant women across the range of pre-pregnancy or first-trimester body mass index (BMI) and performed fetal brain magnetic resonance imaging (MRI) of their healthy singleton fetuses.

Transcription factors are frequent cancer driver genes, exhibiting noted specificity based on the precise cell of origin. We demonstrate that ZIC1 exhibits loss-of-function (LOF) somatic events in group 4 (G4) medulloblastoma through recurrent point mutations, subchromosomal deletions and mono-allelic epigenetic repression (60% of G4 medulloblastoma). In contrast, highly similar SHH medulloblastoma exhibits distinct and diametrically opposed gain-of-function mutations and copy number gains (20% of SHH medulloblastoma).

The Cardiometabolic Index (CMI) is a well-recognized risk factor for a range of cardiovascular diseases and diabetes mellitus. However, the population-level characteristics of CMI and its potential association with mortality risk among individuals over 40 years of age have not been investigated. This study aims to assess the association between CMI and both all-cause and cardiovascular mortality among the middle-aged and elderly population.

Terahertz (THz) lens constitutes a vital component in the THz system. Metasurfaces-based THz metalenses and classical bulky lenses are severely constrained by chromatic/ spherical aberration and the diffraction limit. Consequently, achromatic super-resolution THz lenses are urgently needed.

Autosomal dominant polycystic kidney disease (ADPKD) is the fourth leading cause of end-stage renal disease, contributing substantially to patient morbidity, mortality, and healthcare system strain. Emerging research highlights a pivotal role of epigenetics in ADPKD's pathophysiology, where mechanisms like DNA methylation, histone modifications, and non-coding RNA regulation significantly impact disease onset and progression. These epigenetic factors influence gene expression and regulate key processes involved in cyst formation and expansion, fibrosis, and inflammatory infiltration, thus accelerating ADPKD progression.

Behavior change often requires overcoming discomfort or difficult emotions. Emotional dysregulation associated with anxiety or depression may prevent behavior change initiation among people managing chronic illness. Mindfulness training may catalyze chronic disease self-management by reducing experiential avoidance of aversive experiences that act as barriers to change initiation.

Addressing the global challenge of ensuring access to safe drinking water, especially in developing countries, demands cost-effective, eco-friendly, and readily available technologies. The persistence, toxicity, and bioaccumulation potential of organic pollutants arising from various human activities pose substantial hurdles. While high-performance liquid chromatography coupled with high-resolution mass spectrometry (HPLC-HRMS) is a widely utilized technique for identifying pollutants in water, the multitude of structures for a single elemental composition complicates structural identification.

Background: Currently, it is unclear to what extent late-onset Alzheimer's disease (AD) risk variants contribute to early-onset AD (EOAD). One method to clarify the contribution of late-onset AD genetic risk to EOAD is to investigate the association of AD polygenic risk scores (PRS) with EOAD. We hypothesize that in the Longitudinal Early-Onset Alzheimer's Disease Study (LEADS), EOAD participants will have greater PRS than early-onset amyloid-negative cognitively-impaired participants (EOnonAD) and controls, and investigate the association of AD PRS with age of disease onset (AoO) and cognitive performance.

Background: Chitinase-3-like protein 1 (CHI3L1, or YKL-40) is an important regulator of immunity and, in the brain, is primarily secreted by activated astrocytes and heralds a neurotoxic inflammatory state. While it has been well known as a high-profile biomarker for Alzheimer's disease (AD) and inflammatory brain conditions (e.g.

Background: TBI is the 3rd greatest risk factor for developing AD, behind genetics and aging. TBI is associated with a 3-4 year earlier onset of cognitive impairment, and increased cortical thinning and amyloid plaques in people with AD. The underlying mechanisms of this relationship are not understood, and as a result there are no treatments that protect patients from accelerated AD after TBI.

Background: Autosomal dominant progranulin (GRN) mutations are a common genetic cause of frontotemporal lobar degeneration. Though clinical trials for GRN-related therapies are underway, there is an unmet need for biomarkers that can predict symptom onset and track disease progression. We previously showed that presymptomatic GRN carriers exhibit thalamocortical hyperconnectivity that increases with age when they are presumably closer to symptom onset.

ARIA-E/H (amyloid-related imaging abnormalities-Edema/Hemorrhage) is an umbrella term that defines the radiographic appearance of MRI images abnormality during treatments with Aβ-lowering monoclonal antibodies (mAbs) for Alzheimer's disease immunotherapy. Today, it is well-recognized that ARIA-E events can also occur spontaneously in patients with cerebral amyloid angiopathy-related inflammation (CAA-ri), a rare autoimmune encephalopathy associated with raised cerebrospinal fluid (CSF) concentrations of spontaneous auto-antibodies against Aβ (aAbs). In this framework, the last years of research and experience of the iCAB international Network generated an increased consensus that therapy-induced ARIA is the iatrogenic manifestation of CAA-ri.

Background: The Longitudinal Early-onset Alzheimer's Disease Study (LEADS) is analyzing the genetic etiology of early onset (40-64 years) cognitive impairment, including amyloid-positive early-onset Alzheimer's disease (EOAD) and amyloid-negative early-onset Alzheimer's disease (EOnonAD). One goal of this investigation is to identify novel or under-characterized genetic variants.
Methods: Cognitively impaired (CI) LEADS participants, including amyloid-positive and amyloid-negative early-onset cases, were whole exome or genome sequenced (N = 361).

Background: Frontotemporal dementia (FTD) presents with heterogeneous neuropsychiatric symptoms (NPS). These symptoms often begin prior to the onset of FTD, and progress throughout the prodromal stages of FTD. Particularly, familial FTD due to autosomal dominant genetic mutations might display mutation-specific NPS profiles.
