- Extracellular Hsp72 concentration relates to a minimum endogenous criteria during acute exercise-heat exposure.
- Gibson OR1, Dennis A, Parfitt T, Taylor L, Watt PW, Maxwell NS.Author information 1School of Sport and Service Management, Welkin Science Laboratories, University of Brighton, 30 Carlisle Road, Eastbourne, UK, o.r.gibson@brighton.ac.uk.AbstractExtracellular heat shock protein 72 (eHsp72) concentration increases during exercise-heat stress when conditions elicit physiological strain. Differences in severity of environmental and exercise stimuli have elicited varied response to stress. The present study aimed to quantify the extent of increased eHsp72 with increased exogenous heat stress, and determine related endogenous markers of strain in an exercise-heat model. Ten males cycled for 90 min at 50 % [Formula: see text] in three conditions (TEMP, 20 °C/63 % RH; HOT, 30.2 °C/51%RH; VHOT, 40.0 °C/37%RH). Plasma was analysed for eHsp72 pre, immediately post and 24-h post each trial utilising a commercially available ELISA. Increased eHsp72 concentration was observed post VHOT trial (+172.4 %) (p < 0.05), but not TEMP (-1.9 %) or HOT (+25.7 %) conditions. eHsp72 returned to baseline values within 24 h in all conditions. Changes were observed in rectal temperature (T rec), rate of T rec increase, area under the curve for T rec of 38.5 and 39.0 °C, duration T rec ≥ 38.5 and ≥39.0 °C, and change in muscle temperature, between VHOT, and TEMP and HOT, but not between TEMP and HOT. Each condition also elicited significantly increasing physiological strain, described by sweat rate, heart rate, physiological strain index, rating of perceived exertion and thermal sensation. Stepwise multiple regression reported rate of T rec increase and change in T rec to be predictors of increased eHsp72 concentration. Data suggests eHsp72 concentration increases once systemic temperature and sympathetic activity exceeds a minimum endogenous criteria elicited during VHOT conditions and is likely to be modulated by large, rapid changes in core temperature.

- Elevated levels of extracellular heat-shock protein 72 (eHSP72) are positively correlated with insulin resistance in vivo and cause pancreatic β-cell dysfunction and death in vitro.
- Krause M, Keane K1, Rodrigues-Krause J2, Crognale D, Egan B, De Vito G, Murphy C2, Newsholme P.Author information 1∥School of Biomedical Sciences, CHIRI - Biosciences, Curtin University, Perth, Western Australia 6845.2§Biomedical Research Group, Department of Science, ITT Dublin, Ireland.AbstracteHSP72 (extracellular heat-shock protein 72) is increased in the plasma of both types of diabetes and is positively correlated with inflammatory markers. Since aging is associated with a low-grade inflammation and IR (insulin resistance), we aimed to: (i) analyse the concentration of eHSP72 in elderly people and determine correlation with insulin resistance, and (ii) determine the effects of eHSP72 on β-cell function and viability in human and rodent pancreatic β-cells. Fasting blood samples were collected from 50 older people [27 females and 23 males; 63.4±4.4 years of age; BMI (body mass index)=25.5±2.7 kg/m2]. Plasma samples were analysed for eHSP72, insulin, TNF (tumour necrosis factor)-α, leptin, adiponectin and cortisol, and glycaemic and lipid profile. In vitro studies were conducted using rodent islets and clonal rat and human pancreatic β-cell lines (BRIN-BD11 and 1.1B4 respectively). Cells/islets were incubated for 24 h with eHSP72 (0, 0.2, 4, 8 and 40 ng/ml). Cell viability was measured using three different methods. The impact of HSP72 on β-cell metabolic status was determined using Seahorse Bioscience XFe96 technology. To assess whether the effects of eHSP72 were mediated by Toll-like receptors (TLR2/TLR4), we co-incubated rodent islets with eHSP72 and the TLR2/TLR4 inhibitor OxPAPC (oxidized 1-palmitoyl-2-arachidonoyl-sn-glycero-3-phosphocholine; 30 μg/ml). We found a positive correlation between plasma eHSP72 and HOMA-IR (homoeostasis model assessment of IR) (r=0.528, P<0.001), TNF-α (r=0.389, P<0.014), cortisol (r=0.348, P<0.03) and leptin/adiponectin (r=0.334, P<0.03). In the in vitro studies, insulin secretion was decreased in an eHSP72 dose-dependent manner in BRIN-BD11 cells (from 257.7±33 to 84.1±10.2 μg/mg of protein per 24 h with 40 ng/ml eHSP72), and in islets in the presence of 40 ng/ml eHSP72 (from 0.48±0.07 to 0.33±0.009 μg/20 islets per 24 h). Similarly, eHSP72 reduced β-cell viability (at least 30% for BRIN-BD11 and 10% for 1.1B4 cells). Bioenergetic studies revealed that eHSP72 altered pancreatic β-cell metabolism. OxPAPC restored insulin secretion in islets incubated with 40 ng/ml eHSP72. In conclusion, we have demonstrated a positive correlation between eHSP72 and IR. In addition, we suggest that chronic eHSP72 exposure may mediate β-cell failure.

- HSP72 Is a Mitochondrial Stress Sensor Critical for Parkin Action, Oxidative Metabolism, and Insulin Sensitivity in Skeletal Muscle.
- Drew BG1, Ribas V, Le JA, Henstridge DC, Phun J, Zhou Z, Soleymani T, Daraei P, Sitz D, Vergnes L, Wanagat J, Reue K, Febbraio MA, Hevener AL.Author information 1David Geffen School of Medicine, Department of Medicine, Division of Endocrinology, Diabetes and Hypertension, University of California, Los Angeles, Los Angeles, CA.AbstractIncreased heat shock protein (HSP) 72 expression in skeletal muscle prevents obesity and glucose intolerance in mice, although the underlying mechanisms of this observation are largely unresolved. Herein we show that HSP72 is a critical regulator of stress-induced mitochondrial triage signaling since Parkin, an E3 ubiquitin ligase known to regulate mitophagy, was unable to ubiquitinate and control its own protein expression or that of its central target mitofusin (Mfn) in the absence of HSP72. In wild-type cells, we show that HSP72 rapidly translocates to depolarized mitochondria prior to Parkin recruitment and immunoprecipitates with both Parkin and Mfn2 only after specific mitochondrial insult. In HSP72 knockout mice, impaired Parkin action was associated with retention of enlarged, dysmorphic mitochondria and paralleled by reduced muscle respiratory capacity, lipid accumulation, and muscle insulin resistance. Reduced oxygen consumption and impaired insulin action were recapitulated in Parkin-null myotubes, confirming a role for the HSP72-Parkin axis in the regulation of muscle insulin sensitivity. These data suggest that strategies to maintain HSP72 may provide therapeutic benefit to enhance mitochondrial quality and insulin action to ameliorate complications associated with metabolic diseases, including type 2 diabetes.
