Acetohydroxyacid synthase (AHAS), which catalyzes the first step in the biosynthesis of branched-chain amino acids, is composed of catalytic and regulatory subunits. The enzyme exhibits full activity only when the regulatory subunit (RSU) binds to the catalytic subunit (CSU). However, the crystal structure of the holoenzyme has not been reported ...

The tpg1 mutant of Chlamydomonas lacks the tubulin polyglutamylase TTLL9 and is deficient in flagellar tubulin polyglutamylation. It exhibits slow swimming, whereas the double mutant with oda2 (a slow-swimming mutant that lacks outer-arm dynein) is completely nonmotile. Thus, tubulin polyglutamylation must be important for the functioning of inner-arm dynein(s). In ...

Andalusol (1), conchitriol (2), and lagascatriol (3) are diterpenoids produced by Sideritis species. Hydrogen peroxide-induced oxidative stress in U373-MG cells was used as an in vitro model to evaluate the cytoprotective potential, based on antioxidant properties, of these isolated compounds and to investigate the underlying mechanisms. Experimental results revealed that ...

Papillary fibroelastomas (PFEs) are rare benign tumours of the endocardium, accounting for the most common primary valvular tumours of the heart. They typically originate from left-sided heart valves, whereas pulmonary valve (PV) involvement is anecdotal. They rarely cause valvular dysfunction, but they can cause turbulent flow and thrombus formation with ...

We examined the role of aquaporins in regulating leaf hydraulic conductance (K(leaf) ) in Vitis vinifera L. (cv Chardonnay) by studying effects of aquaporin inhibitors, and aquaporin gene expression during water stress (WS) and recovery (REC). K(leaf) was measured after 3 h of petiole perfusion with different solutions and to ...

Screw implantation inevitably causes microdamage in surrounding bone. However, little is known about the detailed characteristics of microdamage in peri-screw bone. In this study, we developed a method to construct microdamage cast with methylmethacrylate (MMA) and observed the cast using scanning electron microscopy (SEM).

Protein O-glycosylation is important in numerous processes including the regulation of proteolytic processing sites by O-glycan masking in select newly synthesized proteins. To investigate O-glycan-mediated masking using an assay amenable to large-scale screens, we generated a fluorescent biosensor with an O-glycosylation site situated to mask a furin cleavage site. The ...

In vitro studies on HIV (HIV-1) replication and neutralization are usually performed in human cell cultures supplemented with FBS instead of human serum (HS). Here we show that in contrast to FBS, addition of increasing amounts of human serum from noninfected donors to the cell culture directly correlates with an ...

Consecutive proton stimulation reduces ASIC1a peak currents leading to silencing of channels. Kinetic analysis using a fast perfusion system shows that human ASIC1a has two desensitized states with markedly different stabilities. High frequency trains of short stimuli prevent desensitization. The results predict steady ASIC1a responses to high frequency release of ...

Abstract Background: A variety of sepsis models have been used to unravel pathophysiologic processes and to examine the effects of novel therapeutic interventions. The lack of therapeutic efficacy of numerous compounds in clinical sepsis trials, despite glorious results in animal models of sepsis, has raised doubt and debate about the ...

LMX1B, a developmental LIM-homeodomain transcription factor, is widely expressed in vertebrate embryos, and it takes part in the development of diverse structures such as limbs, kidneys, eyes, brains, etc. LMX1B contributes to transcriptional regulation of glomerular basement membrane (GBM) collagen expression by podocytes. The normal function of podocytes and the ...

The high diversity of HIV-1 has been shown to affect disease progression, transmission, and response to antiretroviral therapy; and may influence HIV vaccine design.
