CD4FOXP3Exon2 regulatory T cell frequency predicts breast cancer prognosis and survival.

CD4FOXP3 regulatory T cells (T) suppress immune responses to tumors, and their accumulation in the tumor microenvironment (TME) correlates with poor clinical outcome in several cancers, including breast cancer (BC). However, the properties of intratumoral T remain largely unknown. Here, we found that a functionally distinct subpopulation of T, expressing the FOXP3 Exon2 splicing variants, is prominent in patients with hormone receptor-positive BC with poor prognosis.

Polystyrene nanoparticles induce DNA damage and apoptosis in HeLa cells.

Nanoplastics (NPs) are plastic particles, typically less than 100 nm in size, that result from daily life products as well as the degradation of larger plastic debris. Due to their small size and chemical composition, they can interact with biological systems in ways that larger plastic particles cannot. Humans are continuously exposed to NPs and several studies showed the potentially toxic effects of these latter on health.

Ovariectomy drives increase of an ECM transcription signature in the posterior eye and retina.

Increased risk of developing glaucoma has recently been associated with early age of menopause. Here, we examined how age and surgically-induced menopause via ovariectomy (OVX) impacted gene expression in gene pathways previously linked to glaucoma, such as extracellular matrix (ECM) remodeling and TGF-β signaling. Using bulk RNA sequencing, we analyzed changes in young (3-4 months) and middle-aged (9-10 months) Long-Evans rats.

A Comprehensive Protocol for Microbead-Induced Ocular Hypertension in Mice.

Glaucoma is a common optic neuropathy characterized by degeneration of retinal ganglion cells (RGCs). Elevated intraocular pressure (IOP), that is, ocular hypertension, is the primary modifiable risk factor for glaucoma and the primary characteristic of most preclinical glaucoma models. Extensive genotype and phenotype diversity at relatively low cost and high accessibility makes laboratory mice an excellent preclinical model for glaucoma.

Application of Digital Analysis for Assessment of Coronary Sub-Occlusions in Autopsy Pathology: It Is Time to Move beyond Histology Alone.

Coronary artery disease (CAD) underlies most cases of myocardial infarction (MI), causing or at least contributing to oxygen supply-demand mismatch and myocardial injury, so a careful and reliable evaluation of the main coronary arteries and large branches is a key moment of autopsy in order to establish the cause of death. The aim of this study is to evaluate the application of digital image analysis in the assessment of coronary artery sub-occlusions. A total of 50 coronary sections sampled during 11 consecutive autopsies, regardless of the cause of death, were analyzed.

Colorectal Cancer and Asbestos Exposure: A Women's Health Perspective.

Background: Colorectal cancer (CRC) is considered a "man's disease". However, emerging data show that females may have a higher prevalence of certain risk factors. A potential causal role of asbestos in CRC carcinogenesis has been suggested.

Postmenopausal Hormone Therapy Was Associated With Later Age of Onset Among Glaucoma Cases.

Purpose: Hormonal therapy (HT) has been suggested to lower the risk of developing glaucoma. Our goal was to investigate the association between HT use and the onset of glaucoma diagnosis in postmenopausal women.

Methods: This retrospective case-only study included female veterans with open-angle glaucoma from VA records between 2000 to 2019.

Association of Age of Menopause and Glaucoma Diagnosis in Female Veterans.

Purpose: Age of menopause has been associated with the risk of developing glaucoma; however, it is unclear if the onset of menopause is directly associated with the development of glaucoma. Our objective was to determine if there is an association between the age at diagnosis of menopause and glaucoma.

Methods: This retrospective, case-only analysis was performed using the Veterans Affairs (VA) Corporate Data Warehouse of female veterans from 2000 to 2019.

A method for analyzing AFM force mapping data obtained from soft tissue cryosections.

Atomic force microscopy (AFM) is a valuable tool for assessing mechanical properties of biological samples, but interpretations of measurements on whole tissues can be difficult due to the tissue's highly heterogeneous nature. To overcome such difficulties and obtain more robust estimates of tissue mechanical properties, we describe an AFM force mapping and data analysis pipeline to characterize the mechanical properties of cryosectioned soft tissues. We assessed this approach on mouse optic nerve head and rat trabecular meshwork, cornea, and sclera.

Aging and intraocular pressure homeostasis in mice.

Age and elevated intraocular pressure (IOP) are the two primary risk factors for glaucoma, an optic neuropathy that is the leading cause of irreversible blindness. In most people, IOP is tightly regulated over a lifetime by the conventional outflow tissues. However, the mechanistic contributions of age to conventional outflow dysregulation, elevated IOP and glaucoma are unknown.

A Histomorphometric and Computational Investigation of the Stabilizing Role of Pectinate Ligaments in the Aqueous Outflow Pathway.

Murine models are commonly used to study glaucoma, the leading cause of irreversible blindness. Glaucoma is associated with elevated intra-ocular pressure (IOP), which is regulated by the tissues of the aqueous outflow pathway. In particular, pectinate ligaments (PLs) connect the iris and trabecular meshwork (TM) at the anterior chamber angle, with an unknown role in maintenance of the biomechanical stability of the aqueous outflow pathway, thus motivating this study.

Voluntary exercise preserves visual function and reduces inflammatory response in an adult mouse model of autosomal dominant retinitis pigmentosa.

Whole-body physical exercise has been shown to promote retinal structure and function preservation in animal models of retinal degeneration. It is currently unknown how exercise modulates retinal inflammatory responses. In this study, we investigated cytokine alterations associated with retinal neuroprotection induced by voluntary running wheel exercise in a retinal degeneration mouse model of class B1 autosomal dominant retinitis pigmentosa, I307N Rho.

Pentosan Polysulfate Sodium Causes Diminished Function and Subtle Morphological Changes in Retina and RPE of Mice.

Purpose: There are numerous reports of a distinctive maculopathy in adults exposed to pentosan polysulfate sodium (PPS), a drug prescribed to treat bladder discomfort associated with interstitial cystitis. We tested whether PPS treatment of mice injures RPE or retina to provide insight into the etiology of the human condition.

Methods: Mice were fed PPS-supplemented chow over 14 months.

Polystyrene Microplastics Exacerbate Infection Ability In Vitro and In Vivo.

Plastic pollution is an important environmental problem, and microplastics have been shown to have harmful effects on human and animal health, affecting immune and metabolic physiological functions. Further, microplastics can interfere with commensal microorganisms and exert deleterious effects on exposure to pathogens. Here, we compared the effects of 1 µm diameter polystyrene microplastic (PSMPs) on infection in both in vitro and in vivo models by using HT29 cells and larvae, respectively.
