Nicotinic (cholinergic) neurotransmission plays a critical role in the vertebrate nervous system, underlies nicotine addiction, and nicotinic receptor dysfunction leads to neurological disorders. The C. elegans neuromuscular junction (NMJ) shares many characteristics with neuronal synapses, including multiple classes of postsynaptic currents. Here, we identify two genes required for the major e...

BACKGROUND AND OBJECTIVES In the albumin-to-creatinine ratio (spot-ACR), urine creatinine corrects for tonicity but also reflects muscle mass. Low muscle mass is associated with cardiovascular disease (CVD). We hypothesized that the spot-ACR would be higher in women, lower-weight persons, and older individuals, independent of timed urine albumin excretion (24hr-UAE), and accordingly, that spot-...

BACKGROUND AND PURPOSE Control of nematode parasite infections relies largely on anthelmintic drugs, several of which act on nicotinic ACh receptors (nAChRs), and there are concerns about the development of resistance. There is an urgent need for development of new compounds to overcome resistance and novel anthelmintic drug targets. We describe the functional expression and pharmacological cha...

OBJECTIVES The aim of this study was to determine whether chronic kidney disease (CKD) is associated with hearing thresholds in the nationwide, large-scaled Korean population. METHODS This study analyzed the data of 9,798 subjects of 19 years and older (4,387 males and 5,411 females). Urine albumin-to-creatinine ratio (ACR) was measured from first-voided spot urine samples. The air-conduction...

Neuropeptides play crucial roles in modulating neuronal networks, including changing intrinsic properties of neurons and synaptic efficacy. We previously reported a Caenorhabditis elegans mutant, acr-2(gf), that displays spontaneous convulsions as the result of a gain-of-function mutation in a neuronal nicotinic acetylcholine receptor subunit. The ACR-2 channel is expressed in the cholinergic m...

BACKGROUND Patients with type 2 diabetes mellitus and elevated urinary albumin:creatinine ratio (ACR) have increased risk of heart failure. We hypothesized this was because of cardiac tissue changes rather than silent coronary artery disease. METHODS AND RESULTS In a case-controlled observational study 130 subjects including 50 ACR+ve diabetes mellitus patients with persistent microalbuminuri...

Acyclic retinoid (ACR), a novel synthetic retinoid, can prevent the recurrence of human hepatoma after surgical resection of primary tumors, but the molecular mechanisms by which ACR exerts antitumor effects are not known. In this study, we found that ACR inhibited the growth of three human hepatoma cell lines. In HepG2 cells, this inhibition was associated with an arrest of the cell cycle in G...

Monepantel is a member of the recently identified class of anthelmintics known as the amino-acetonitrile derivatives (AADs). Monepantel controls all major gastro-intestinal nematodes in sheep including those that are resistant to the classical anthelmintics. Previous studies have shown that the Caenorhabditis elegans acr-23 and the Haemonchus contortus Hco-mptl-1 genes may be prominent targets ...

Acrylamide (ACR) is a chemical compound with severe neurotoxicity, genotoxicity, carcinogenicity and reproductive toxicity. Recent studies showed that ACR impairs the function of reproductive organs, e.g., epididymis and testes. In vitro maturation of mouse oocyte is a sensitive assay to identify potential chemical hazard to female fertility. The aim of this study was to evaluate the adverse ef...
