2023-12-04
Chromatin proteins play important roles in gene expression and DNA repair. The importance of chromatin composition on gene expression is exemplified by X-inactivation, where one of the two X chromosomes in female mammalian IL-18, human recombinant protein is transcriptionally silenced by heterochro

2023-12-04
ATM-dependent initiation of radiation-induced G2/M checkpoint arrest is well established [11], [34], [35]. However, the ATR pathway may also be involved [36], [37]. Brown and Baltimore generated Cre/lox-conditional cell lines or 76 7 with a kinase inactive allele of ATR (ATRkd) to evaluate the role

Receptors containing an αx/γy subunit interface, where x=1, 2, 3, 5 and y=1–3, form a high-affinity binding site for benzodiazepines (Figure 1A), for the later developed Z-drugs of different chemotypes, and for a large number of chemically distinct research compounds 17, 18 (Box 1 for examples). Fo

Introduction Cytochrome P450 19 (CYP19; aromatase) catalyzes the conversion of androgens to estrogens in a three-reaction sequence, where each step depends on NADPH and O2 [[1], [2], [3]]. The first two steps are accepted to be hydroxylations of the steroid C19 methyl group, whereas the final step

2023-12-04
Recently, competitive inhibitors of arginase have been developed which have greater specificity for the enzyme. Initial development of these compounds involved determination of the crystal structure of arginase. Christianson and colleagues found that a binuclear manganese cluster was required for ca

Apelin/APJ triggers a variety of cellular signaling pathways (Fig. 1). Recent studies from our laboratory showed that apelin-13 induces vascular smooth muscle cell (VSMC) proliferation by the upregulation of Cyclin D1 expression, which is involved in an ERK-dependent activation of Jagged-1/Notch3 si

Conflicts of interest Introduction When it comes to risk taking, surgeons and anesthesiologists show greater risk taking than other physicians. Surgical procedures carry several risks of which infection is one. Surgical site infections (SSI) are the most common hospital acquired infection and

Angiogenesis refers to the formation of new blood vessels from pre-existing vasculature [1]. Physiological angiogenesis is necessary for key processes such as wound healing, tissue regeneration and repair. In pathological conditions, including cardiovascular diseases, diabetes, cancer, and other pat

Alzheimer’s disease (AD) is an irreversible, age-associated neurodegenerative disorder that is characterized by progressive memory loss and cognitive decline. AD is also the leading cause of dementia, accounting for 5 million cases in the United States and 44 million cases worldwide. In 2015, AD c

Aβ and tau in Alzheimer's disease The two classical histopathological hallmarks of AD are extracellular insoluble Aβ deposits, known as Aβ plaques, and intracellular accumulations of insoluble microtubule-associated tau protein, known as neurofibrillary tangles [14]. Aβ peptides are produced as a

A limitation of the 2011 NIA-AA recommendations was that biomarkers were grouped into just two categories—amyloid and tau-related neurodegeneration. Tauopathy and neurodegeneration were placed into the same biomarker category. In persons with only AD, it is reasonable to assume that neurodegeneratio

The fact that Yoda1 can activate Piezo1 in the absence of other cellular components other than a cell membrane [2], suggests that it may directly interact with and activate Piezo1. However, this does not preclude Yoda1 from interacting and activating non-Piezo channels, particularly in endothelial c

Notably, β2AR and β3AR signaling can also occur via mechanisms independent from G protein [13]. Additionally, the response to GPCR stimulus can be modified by various parameters, including chronic stimulation, cell hypoxia, acidosis, and aging [14], [15], [16]. GRKs have a significant role in the r

PKA signalling in the nucleus was thought to be due to the translocation of the catalytic subunit upon activation from the AT9283 receptor to the nucleus via diffusion [72]. However, a new understanding has emerged, as both the regulatory and catalytic subunits have been identified in the nucleus an

The central problem in amnesia developing following impairment of long-term memory consolidation or reconsolidation is a question of the underlying mechanisms, whether it is caused by impairment of retrieval or memory storage mechanisms [3,8,9,[15], [16], [17], [18]]. To answer this question, severa
