BACKGROUND Cigarette smoking is associated with an increased risk of type 2 diabetes mellitus (T2DM). Smokers exhibit low circulating levels of total adiponectin (ADPN) and high-molecular-weight (HMW) ADPN multimers. Blood concentrations of HMW ADPN multimers closely correlate with insulin sensitivity for handling glucose. How tobacco smoke exposure lowers blood levels of ADPN, however, has not...

Few studies addressed the relation of visceral adiposity and high-molecular weight (HMW) adiponectin to arterial stiffness. We investigated the impact of visceral adipose tissue (VAT) and HMW adiponectin on cardio-ankle vascular index (CAVI) in asymptomatic Japanese subjects. We studied 487 consecutive subjects (271 men and 216 women) who underwent general health examination between October 200...

OBJECTIVE Serum C-reactive protein (CRP) and adiponectin levels predict atherosclerosis and coronary heart disease. However, the efficacy of the combination of both markers remains unknown. In the present study, we investigated whether the combination of CRP and adiponectin is associated with further metabolic abnormalities compared to each of them alone. RESEARCH DESIGN AND METHODS Eighty-th...

Haemorrhagic fever with renal syndrome (HFRS) is characterised by an uncontrolled immune response that causes vascular leakage. Adiponectin (APN) is an adipocytokine involved in prorevascularisation and immunomodulation. To investigate the possible effects of APN in the pathogenesis of HFRS, total and high molecular weight (HMW) APN levels in the plasma of patients with HFRS were quantified usi...

Nontypeable Haemophilus influenzae (NTHi) is a common cause of localized respiratory tract disease and initiates infection by colonizing the nasopharynx. Approximately 75 to 80% of NTHi clinical isolates produce proteins that belong to the HMW family of adhesins, which are believed to facilitate colonization. The prototype HMW adhesins are designated HMW1 and HMW2 and were identified in NTHi st...

High molecular weight (HMW) hyaluronan (HA) is widely distributed in the extracellular matrix, but its biological activities remain incompletely understood. We previously reported that HMW-HA binding to CD44 antagonizes mitogen-induced S-phase entry in vascular smooth muscle cells (SMCs; Cuff, C.A., D. Kothapalli, I. Azonobi, S. Chun, Y. Zhang, R. Belkin, C. Yeh, A. Secreto, R.K. Assoian, D.J. ...

The two types of the rat kininogen genes show different modes of mRNA production. The K gene encodes two distinct mRNAs for high molecular weight (HMW) and low molecular weight (LMW) kininogens. These two mRNAs are generated by differential usage of the 3'-terminal exon (LMW exon) and the one next to this exon (HMW exon) through alternative polyadenylation and splicing. In contrast, the two T g...

Inactive renin has been isolated from pooled amniotic fluid and purified approximately 642-fold. Prior to activation the isolates had approximately 4% of the activity found after activation. The observation is similar to that reported for inactive renin from chorionic cell culture and suggests a placental origin of amniotic fluid inactive renin. Using plasma from an estrogen-treated woman, reni...

INTRODUCTION Whether adiponectin levels associate with atherogenesis in RA is uncertain. We examined the independent relationships of total and high molecular weight (HMW) adiponectin concentrations with cardiometabolic risk and surrogate markers of enhanced early atherogenesis in black and white patients with RA. METHODS We determined total and HMW adiponectin concentrations and those of end...

BACKGROUND Adiponectin is linked to reduced diabetes risk and may be antiatherogenic, yet clinical data show no consistent relationship with incident cardiovascular events, especially among women. To our knowledge, no prior prospective studies have evaluated adiponectin, including high-molecular-weight (HMW) adiponectin, and incident peripheral artery disease (PAD). METHODS AND RESULTS We eva...
