Glioblastomas are characterized by a variety of genetic and epigenetic disorders, identification of which allows constantly expanding a list of genes directly involved in carcinogenesis, thus increasing molecular diagnostics, monitoring and predicting disease. Molecular-genetic studies of patients with glioblastomas allowed revealing changes relevant to this disease and determining their prognostic significance. In the future molecular-biological markers along with clinical and therapeutic factors may play a role of separate and independent factors of prognosis in patients with malignant brain lesions.

Department of Medicine, Harvard Medical School, Boston, Massachusetts.
Importance: Disease characteristics of genetically mediated coronary artery disease (CAD) on coronary angiography and the association of genomic risk with outcomes after coronary angiography are not well understood.
Objective: To assess the angiographic characteristics and risk of post-coronary angiography outcomes of patients with genomic drivers of CAD: familial hypercholesterolemia (FH), high polygenic risk score (PRS), and clonal hematopoiesis of indeterminate potential (CHIP).
Design, Setting, And Participants: A retrospective cohort study of 3518 Mass General Brigham Biobank participants with genomic information who underwent coronary angiography was conducted between July 18, 2000, and August 1, 2023.

Hypertension, commonly known as high blood pressure, is a significant health issue that increases the risk of cardiovascular diseases, stroke, and renal failure. This condition broadly encompasses both primary and secondary forms. Despite extensive research, the underlying mechanisms of systemic arterial hypertension-particularly primary hypertension, which has no identifiable cause and is affected by genetic and lifestyle agents-remain complex and not fully understood.

Long-read sequencing has emerged as a transformative technology in recent years, offering significant potential for the molecular diagnosis of unresolved genetic disorders. Despite its promise, the comprehensive detection and clinical annotation of genomic variants remain intricate and technically demanding. We present SUMMER, an integrated and structured workflow specifically designed to process raw Nanopore sequencing reads.

This study aimed to evaluate the therapeutic efficacy of camellia oil on 2,4-dinitrochlorobenzene (DNCB)-induced atopic dermatitis (AD) in mice, as well as its effect on the expression of skin-barrier-related proteins. A mouse model of AD was created via topical application of DNCB; subsequently, the animals were randomly divided into four groups: the blank control (Control), model (Model), moisturizing cream (Moisturizer), and camellia oil (Camellia) groups. The Camellia group received camellia oil, whereas the Moisturizer group was treated with moisturizing cream, as a positive control.

Hematopoietic stem cells (HSCs) are susceptible to replication stress, which is a major contributor to HSC defects in Fanconi anemia (FA). Here, we report that HSCs relax the global chromatin by downregulating the expression of a chromatin architectural protein, DEK, in response to replication stress. DEK is abnormally accumulated in bone marrow (BM) CD34+ cells from patients with FA and in Fancd2-deficient HSCs.
