The present results not only provided new insights into the interaction mechanism of RXFP3 with agonists and antagonists, but also demonstrated usefulness of the NanoBiT-based homogenous binding assay to study the interaction mechanism of certain receptors with their ligands.Terror management theory proposes cultural worldview and self-esteem as two buffers against death anxiety. The neural mediators of these buffering effects, however, have not been fully understood. The present work investigated neural mediation mechanisms between self-esteem/cultural trait (self-construal) and mortality salience (MS) effects on self-face processing. We found that MS (vs. NA) priming eliminated self-face advantage in behavioral judgments of face-orientation in low self-esteem individuals and reduced self-face advantage in behavioral judgments of facial-familiarity in individuals with high interdependent self-construals. Our functional magnetic resonance imaging (fMRI) results showed that, following MS priming, insular activities mediated the relationship between self-esteem and self-face advantage in face-orientation judgments, whereas dorsal medial prefrontal activity mediated the relationship between interdependent self-construal and self-face advantage in face-familiarity judgments. Our findings suggest that distinct neural mechanisms are engaged in mediating the relationships between self-esteem/cultural trait and MS effects on the emotional and cognitive processes of self-relevant information.Microalgae have many commercial applications including biofuel production, use in human and animal nutrition, as pharmaceuticals and therapeutic compounds, in beauty-related products and as biofertilizers in the agricultural sector. However, more research needs to be directed to reducing production costs in an environmentally friendly way before their commercial potential can be fully realized. This review discusses the current knowledge on the occurrence and physiological roles of phytohormones in microalgae and explores the potential of phytohormone treatments to improve cultivation practices, including increasing lipid content and productivity for biofuel production. Microalgae synthesize a wide array of phytohormones and are able to regulate the levels of active phytohormones. Biosynthetic and conversion pathways share some key components but are more rudimentary compared to vascular plants and are likely to have some unidentified conjugation mechanisms. Phytohormones have a dual function in microalgae. Specific phytohormones are involved in the regulation of the cell cycle and other metabolic processes, influencing biomass and primary metabolite accumulation. They are also involved in responses to abiotic stresses, allowing microalgae to adapt to the prevailing conditions. Phytohormones provide a promising strategy to improve mass culture biotechnology due to their intrinsic role in microalgal growth and survival, increasing lipid productivity and improving their tolerance to more extreme environmental changes. This makes them less susceptible to environmental fluctuations. This improves the productivity of the cultures for biofuel production and would be beneficial in a biorefinery approach. Overall, phytohormones provide an exciting and promising avenue of research to improve microalgae cultivation, taking it a step closer to successful commercialization.
Heparan sulfate (HS) is a sulfated linear polysaccharide on cell surfaces that plays an important role in physiological processes. HS is present in skeletal muscles but its detailed role in this tissue remains unclear.

We examined the role of HS in the differentiation of C2C12 cells, a mouse myoblast cell line. We also phenotyped the impact of HS deletion in mouse skeletal muscles on their functions by using Cre-loxP system.

CRISPR-Cas9-dependent HS deletion or pharmacological removal of HS dramatically impaired myoblast differentiation of C2C12 cells. To confirm the importance of HS in vivo, we deleted Ext1, which encodes an enzyme essential for HS biosynthesis, specifically in the mouse skeletal muscles (referred to as mExt1CKO mice). Treadmill and wire hang tests demonstrated that mExt1CKO mice exhibited muscle weakness. The contraction of isolated soleus muscles from mExt1CKO mice was also impaired. Morphological examination of mExt1CKO muscle tissue under light and electron microscopes revealed smaller cross sectional areas and thinner myofibrils. Finally, a model of muscle regeneration following BaCl
injection into the tibialis anterior muscle of mice demonstrated that mExt1CKO mice had reduced expression of myosin heavy chain and an increased number of centronucleated cells. This indicates that muscle regeneration after injury was attenuated in the absence of HS expression in muscle cells.

These results demonstrate that HS plays an important role in skeletal muscle function by promoting differentiation.

Ursolic acid (UA) is a natural triterpenoid which possesses anti-cancer activity. However, little is known regarding the activity and molecular mechanism of UA in cholangiocarcinoma (CCA). TPX-0046 concentration Thus, we investigated the effects of UA on growth inhibition and apoptosis induction through biomolecular changes in KKU-213 and KKU-055 CCA cell lines.

The anti-proliferative effect of UA against CCA cells was evaluated using SRB assay. Changes in biomolecules were assessed by SR-FTIR microspectroscopy combined with PCA and conventional methods (i.e., Annexin V-FITC/PI staining for lipid alteration and apoptosis induction; Western blot analysis and caspase-3/7 activity assay for apoptotic protein detection).

UA suppressed the proliferation of CCA cells in a dose- and time-dependent manner. SR-FTIR data revealed a significant alteration in lipids attributable to changes in apoptotic cell membranes, confirmed by Annexin V-FITC/PI staining. SR-FTIR data showed that UA promoted changes in the protein secondary structure. Elevated expression of Bax and decreased expression of Bcl-2 and survivin/BIRC5 along with augmented caspase-3/7 activity supported alterations in apoptosis-related proteins.

SR-FTIR microspectroscopy was successfully used as a label-free technique to monitor apoptosis-induced biomolecular changes in UA-treated CCA cells. UA exerted the cytotoxic and apoptotic activities in CCA cells through alterations in membrane lipids and apoptotic proteins. UA could be a potential anti-CCA candidate and a chemical starting point for the discovery of novel anti-cancer agents.

Our present study showed the first evidence that UA exhibited the anti-proliferative and pro-apoptotic activities toward CCA cells through changes in biomolecules, notably lipids and proteins.

Conflicting data exists regarding the association between sex and mortality in adults with in-hospital (IHCA) and out-of-hospital cardiac arrest (OHCA). We therefore conducted a meta-analysis to investigate the association between sex and mortality in adults with IHCA and OHCA.

We systematically searched MEDLINE and Cochrane databases to identify studies reporting sex-specific mortality in adults following IHCA or OHCA from inception to April 2020. Data were pooled using random-effects models. The primary outcome of interest was in-hospital (or 30-day) all-cause mortality.

We included 21 observational studies with a total of 1,029,978 adult patients - 622,085 men and 407,893 women. Seven studies included patients only with IHCA and 14 studies included patients only with OHCA. Female sex was associated with significantly higher mortality following OHCA [odds ratio (OR) 1.56, 95% confidence interval (CI) 1.32-1.84, p < 0.001) and a trend toward higher mortality following IHCA (OR 1.10, 95%CI 1.00-1.20, p = 0.052).

In adults with cardiac arrest, female sex was associated with significantly higher mortality following OHCA and a trend toward higher mortality following IHCA.

In our previous study, we have found that lipid-related constituents in the host cellular membrane are associated with the BmCPV life cycle. It is important to note that the lipids not only affect the cellular biological processes, they also impact the virus life cycle. However, the intracellular lipid homeostasis in BmN cells after BmCPV infection remains unclear. Here, the lipid metabolism in BmCPV-infected BmN cells was studied by lipidomics analysis. Our results revealed that the intracellular lipid homeostasis was disturbed in BmN cells upon BmCPV infection. Major lipids constituents in cellular membrane were found to be significantly induced upon BmCPV infection, which included triglycerides, phosphatidylcholine, phosphatidylethanolamine, sphingomyelin, phospholipids, glucoside ceramide, monoetherphosphatidylcholin, ceramide, ceramide phosphoethanolamine and cardiolipin. Further analysis of the pathways related to these altered lipids (such as PE and PC) showed that glycerophospholipid metabolism was one of the most enriched pathways. These results suggested that BmCPV may manipulate the lipid metabolism of cells for their own interest. The findings may facilitate a better understanding of the roles of lipid metabolic changes during virus infection in future studies.MicroRNAs (miRNAs) are single-strand endogenous and non-coding RNA molecules with a length of about 22 nucleotides, which regulate genes expression, through modulating the translation and stability of their target mRNAs. miR-146a is one of the most studied miRNAs, due to its central role in immune system homeostasis and control of the innate and acquired immune responses. Accordingly, abnormal expression or function of miR-146a results in the incidence and progression of immune and non-immune inflammatory diseases. Its deregulated expression pattern and inefficient function have been reported in a wide spectrum of these illnesses. Based on the existing evidence, this miRNA qualifies as an ideal biomarker for diagnosis, prognosis, and activity evaluation of immune and non-immune inflammatory disorders. Moreover, much attention has recently been paid to therapeutic potential of miR-146a and several researchers have assessed the effects of different drugs on expression and function of this miRNA at diverse experimental, animal, besides human levels, reporting motivating results in the treatment of the diseases. Here, in this comprehensive review, we provide an overview of miR-146a role in the pathogenesis and progression of several immune and non-immune inflammatory diseases such as Rheumatoid arthritis, Systemic lupus erythematosus, Inflammatory bowel disease, Multiple sclerosis, Psoriasis, Graves' disease, Atherosclerosis, Hepatitis, Chronic obstructive pulmonary disease, etc., discuss about its eligibility for being a desirable biomarker for these disorders, and also highlight its therapeutic potential. Understanding these mechanisms underlies the selecting and designing the proper therapeutic targets and medications, which eventually facilitate the treatment process.
