MicroRNAs (miRNAs), a class of non-coding RNAs, are utilized as biomarkers for a wide range of disorders. Circulating miRNAs are proposed as potential markers in the clinical identification of heart failure (HF). However, identifying miRNA biomarkers in HF requires identification of robust endogenous control miRNAs for normalization in differential expression analysis. Hence, this study aimed to identify circulating miRNAs that can be utilized as endogenous controls in HF. We evaluated the expression of eight miRNAs, which were previously reported as endogenous controls in different pathological conditions. Total RNA, including miRNA, was extracted from the serum samples of 30 HF patients (15 HFrEF and 15 HFpEF) and their matched controls (n = 15). We used quantitative PCR to determine the miRNA expression. The stability of the selected endogenous miRNAs was assessed and compared using a standard set of criteria with the RefFinder software. Six of the eight miRNAs analyzed showed consistent expression among all sample groups. Stability analysis ranked hsa-let-7i-5p, hsa-miR-148b-3p, and hsa-miR-484 as the most stable miRNAs, indicating their potential as reliable endogenous controls.

In this article, a biophysically realistic model of a soft octopus arm with internal musculature is presented. The modeling is motivated by experimental observations of sensorimotor control where an arm localizes and reaches a target. Major contributions of this article are: (i) development of models to capture the mechanical properties of arm musculature, the electrical properties of the arm peripheral nervous system (PNS), and the coupling of PNS with muscular contractions; (ii) modeling the arm sensory system, including chemosensing and proprioception; and (iii) algorithms for sensorimotor control, which include a novel feedback neural motor control law for mimicking target-oriented arm reaching motions, and a novel consensus algorithm for solving sensing problems such as locating a food source from local chemical sensory information (exogenous) and arm deformation information (endogenous).

Synthetic biology often employs heterologous enzymatic reactions to reprogram cell metabolism or otherwise introduce novel functions. However, precise control of a particular metabolic pathway can be difficult to achieve because cofactors are shared with endogenous enzymes from a common pool. Recently, the use of noncanonical cofactors (NCCs) has emerged as a promising approach to bypass this problem by isolating desired reactions without the need for a physical barrier.

In this study, we identified a new chicken-specific protein, named chicken interferon-related antiviral protein (chIRAP) after sequence analysis and comparison, which inhibited the proliferation of various viruses including influenza A virus (IAV) and Newcastle Disease Virus (NDV) in vitro, and chicken embryos with high expression of chIRAP reduced IAV infection. Mass spectrometry analysis of chIRAP interacting proteins and screening of interacting proteins affecting the function of chIRAP revealed that the deletion of endogenous chicken peroxiredoxin 1 (chPRDX1) significantly reduced the antiviral effect of chIRAP. In order to clarify the functional site of chPRDX1 affecting the antiviral effect of chIRAP, we constructed the point mutants of chPRDX1 based on the results of molecular docking (D79A, T90A, K93A, Q94A, R110A, R123A), and screened the sites affecting the antiviral effects of chIRAP by knockdown of endogenous chPRDX1 combined with the overexpression mutant strategy, the results showed that the mutations in the sites affected the antiviral effects of chIRAP to different degrees, with D79A being the most significant, and the D79A mutation of chPRDX1 reduces the ability of chPRDX1 to regulate reactive oxygen species (ROS).

Nitric oxide (NO) is essential for cardiovascular health and is purported as an ergogenic aid. Endothelial dysfunction and reduced endogenous NO production are hallmarks of heart failure (HF), which may contribute to impaired exercise capacity. Oral inorganic nitrate supplementation offers an exogenous route to increase bioavailable NO via reduction of nitrate by oral commensal bacteria.

While the cancer genome is well-studied, the nongenetic exposome of cancer remains elusive, particularly for regionally prevalent cancers with poor prognosis. Here, by employing a combined knowledge- and data-driven strategy, we profile the chemical exposome of plasma from 53 healthy controls, 14 esophagitis and 101 esophageal squamous cell carcinoma (ESCC) patients, and 46 esophageal tissues across 12 Chinese provinces, integrating inorganic, endogenous, and exogenous chemicals. We first show that components of the ESCC chemical exposome mediate the relationship between ESCC-related dietary/lifestyle factors and clinic health status indicators.
