Calorie restriction (CR) has a positive impact on health and lifespan. Previous work however does not reveal the whole underlying mechanism of behavioral phenotypes under CR. We propose a new approach based on phase space reconstruction (PSR) to analyze the behavioral responses of mice to graded CR. This involved reconstructing high-dimensional attractors which topologically represent the intrinsic dynamics of mice based on low-dimensional time series of movement counts observed during the 90 day time course of restriction. PSR together with correlation dimensions (CD), Kolmogorov entropy (KE) and multifractal spectra builds a map from internal attractors to the phenotype of mice and reveals the mice with increasing CR levels undergo significant changes from a normal to a new state. Features of the attractors (CD and KE) were significantly associated with gene expression profiles in the hypothalamus of the same individuals. © The Author(s) 2020.

Although termination of protein synthesis is highly efficient, errors in decoding of stop codons may lead to the synthesis of C-terminally extended proteins. It was found that in eukaryotes such elongated proteins do not accumulate in cells. However, the mechanism for sequestration of C-terminally extended proteins is still unknown. Here we show that 3'-UTR-encoded polypeptides promote aggregation of the C-terminally extended proteins, and targeting to lysosomes. We demonstrate that 3'-UTR-encoded polypeptides can promote different levels of protein aggregation, similar to random sequences. We also show that aggregation of endogenous proteins can be induced by aminoglycoside antibiotics that promote stop codon read-through, by UAG suppressor tRNA, or by knokcdown of release factor 1. Furthermore, we find correlation between the fidelity of termination signals, and the predicted propensity of downstream 3'-UTR-encoded polypeptides to form intrinsically disordered regions. Our data highlight a new quality control mechanism for elimination of C-terminally elongated proteins. © The Author(s) 2020.

The TERRA RNA repeats can exist in single stranded, RNA-DNA hybrid and G-quadruplex forms in the cell. Interaction of TERRA RNA with hnRNPA1 has been proposed to play critical roles in maintenance of telomere DNA. hnRNPA1 contains an N-terminal UP1 domain followed by an RGG-box containing C-terminal region. RGG-motifs are emerging as key protein motifs that recognize the higher order nucleic acid structures as well as are known to promote liquid-liquid phase separation of proteins. In this study, we have shown that the RGG-box of hnRNPA1 specifically recognizes the TERRA RNA G-quadruplexes that have loops in their topology, whereas it does not interact with the single-stranded RNA. Our results show that the N-terminal UP1 domain in the presence of the RGG-box destabilizes the loop containing TERRA RNA G-quadruplex efficiently compared to the RNA G-quadruplex that lacks loops, suggesting that unfolding of G-quadruplex structures by UP1 is structure dependent. Furthermore, we have compared the telomere DNA and TERRA RNA G-quadruplex binding by the RGG-box of hnRNPA1 and discussed its implications in telomere DNA maintenance. © The Author(s) 2020.

Experiments were conducted in Pasco (Peru) in four different orchards, over 2 yr (2016 and 2017), two orchards per year. Choice (granadilla plus natural host) and no-choice foraging behavior trials were conducted using sleeves under field conditions, and forced infestation was examined in laboratory cages, with five females per fruit. The development time of C. capitata was determined, and the oviposition behavior of C. capitata and A. fraterculus was examined. Three fruit maturity stages of intact (n = 1,320) and punctured (n = 1,320) granadilla fruits were examined. Adult C. capitata (n = 4,418) and A. fraterculus (n = 2,484) were trapped in the orchards, and commercial granadilla fruits (n = 1,940) sampled and dissected. Fruit fly infestation was not found in any intact granadilla fruits. Larvae and pupae were found inside punctured granadilla only in fruits broken after 20 d, and adults only emerged when those pupae were removed from the fruit. Ceratitis capitata development time was longer in punctured granadilla than that in host fruit. In the oviposition test, A. fraterculus and C. capitata did not lay eggs in intact granadilla, and C. capitata laid eggs in punctured fruits but larvae were not found. Because of the resistance mechanisms of the pericarp, commercial fruits of Passiflora ligularis are not a natural host of C. capitata and A. fraterculus in Peru. © The Author(s) 2020.

However, there is large variation in the individual risk to develop obesity-associated comorbid diseases which cannot simply be explained by the extent of adiposity. Observations that a proportion of individuals with obesity have a significantly lower risk for cardiometabolic abnormalities led to the concept of metabolically healthy obesity (MHO). Although there is no clear definition, normal glucose and lipid metabolism parameters in addition to the absence of hypertension usually serve as criteria to diagnose MHO. Biological mechanisms underlying MHO include lower ectopic (visceral and liver) and higher leg fat deposition, expandability of subcutaneous adipose tissue, preserved insulin sensitivity and beta-cell function as well as better cardiorespiratory fitness compared to unhealthy obesity. [https://www.selleckchem.com/products/ly2874455.html find more] Whereas the absence of metabolic abnormalities may reduce the risk of type 2 diabetes and cardiovascular diseases in metabolically healthy compared to unhealthy individuals with obesity, it is still higher in comparison with healthy lean people.
