RNAscope 2.5 HD Red assay

Fetal bovine serum (FBS) is used commonly in cell culture. Charcoal-stripped FBS (CS-FBS) is used to study androgen responsiveness and androgen metabolism in cultured CaP cells. Switching CaP cells from FBS to CS-FBS may reduce activity of androgen receptor (AR), inhibit cell proliferation, or modulate intracellular androgen metabolism. Removal of proteins by charcoal stripping may cause changes in biological functions.

Abstract

BACKGROUND:

Genome-wide association studies conducted on QRS duration, an electrocardiographic measurement associated with heart failure and sudden cardiac death, have led to novel biological insights into cardiac function. However, the variants identified fall predominantly in non-coding regions and their underlying mechanisms remain unclear.

RESULTS:

Previously, several studies have been performed to delineate the development and progression of Marburg virus infection in nonhuman primates (NHPs), primarily to clarify the mechanisms of severe (fatal) disease. After the 2013–2016 Ebola virus disease (EVD) epidemic in Western Africa, there has been a reassessment of the available filovirus animal models and the utility of these to faithfully recapitulate human disease. The high lethality of the NHP models has raised doubts as to their ability to provide meaningful data for the full spectrum of disease observed in humans.

Abstract

OBJECTIVE:

Modification of hyaluronan (HA) accumulation has been shown to play a key role in regulating inflammatory processes linked to the progression of multiple sclerosis (MS). The aim of this study was to characterize the enzymatic activity involved in HA degradation observed within focal demyelinating lesions in the experimental autoimmune encephalomyelitis (EAE) animal model.

METHODS:

Oncogene-induced senescence is a potent tumor-suppressive response. Paradoxically, senescence also induces an inflammatory secretome that promotes carcinogenesis and age-related pathologies. Consequently, the senescence-associated secretory phenotype (SASP) is a potential therapeutic target. Here, we describe an RNAi screen for SASP regulators. We identified 50 druggable targets whose knockdown suppresses the inflammatory secretome and differentially affects other SASP components.

Cleft palate is one of the most common craniofacial congenital defects in humans.

Pyramidal neurons express rich repertoires of leucine-rich repeat (LRR)-containing adhesion molecules with similar synaptogenic activity in culture. The in vivo relevance of this molecular diversity is unclear. We show that hippocampal CA1 pyramidal neurons express multiple synaptogenic LRR proteins that differentially distribute to the major excitatory inputs on their apical dendrites.

Uterine glands are essential for pregnancy establishment. By employing forkhead box A2 (FOXA2)-deficient mouse models coupled with leukemia inhibitory factor (LIF) repletion, we reveal definitive roles of uterine glands in embryo implantation and stromal cell decidualization. Here we report that LIF from the uterine glands initiates embryo-uterine communication, leading to embryo attachment and stromal cell decidualization.

Abstract

BACKGROUND:

Vertical transmission of Zika virus (ZIKV) leads to infection of neuroprogenitor cells and destruction of brain parenchyma. Recent evidence suggests that the timing of infection as well as host factors may affect vertical transmission. As a result, congenital ZIKV infection may only become clinically apparent in the postnatal period.

OBJECTIVES:

Reduced expression of GM1 and other major brain gangliosides GD1a, GD1b and GT1b have been reported in Parkinson's disease (PD) brain. Mechanisms underlying these changes are unclear but may be due to a deficit in the ganglioside biosynthetic process.
