Genipin is an important monoterpene iridoid compound isolated from Gardenia jasminoides J.Ellis fruits and from Genipa americana fruits, or genipap. It is a precursor of a blue pigment which may be attractive alternative to existing food dyes and it possesses various potential therapeutic properties such as anti-cancer, anti-diabetic and hepatoprotective activity. Biomedical studies also show that genipin may act as a neuroprotective drug. This review describes new aspects of the bioactivity of genipin against various diseases, as well as its toxicity and industrial applications, and presents its potential mechanism of action.

Social support has been linked to lower cardiovascular morbidity and mortality. However, most studies have examined perceived support as an intrapersonal construct. A dyadic approach to social support highlights how interdependence between individuals within relationships, including partner perceptions and interactions, can influence one’s health. This study’s overall purpose was to test actor–partner models linking perceived social support to inflammation. Ninety-four cisgender married couples completed perceived support measures and had their blood drawn for CRP and IL-6 to produce an overall inflammatory index. The primary results indicate that only a partner’s level of perceived support was related to lower inflammation in their spouse. Our sample size, although moderate for inflammatory studies, was probably not large enough to detect actor influences. These data highlight the importance of taking a dyadic perspective on modeling perceived support and its potential mechanism.

Abstract Background: Skin melanoma is a malignant tumor originated from skin melanocytes. It is highly malignant and easy to relapse and metastasis. Finding new diagnostic and therapeutic targets has become a hot issue. Accumulating evidence now indicates that thyroid hormone receptor interactor 13 (TRIP13) plays important roles in tumor development. However, its role in melanoma remains unclear.Methods: Bioinformatic analyses were employed to excavate crucial genes in melanoma using several public databases. The expression of TRIP13 was detected by immunohistochemistry. MV3 cell and A2058 cell were steadily transfected with TRIP13 knock-down or overexpression lentiviruses, then the function and potential mechanism of TRIP13 were studied in vitro and in vivo. Co-immunoprecipitation (Co-IP) and mass spectrum were employed to screen out the interacting molecule of TRIP13.Results: Our results showed that TRIP13 was generally upregulated in melanoma tissues and was related to the poor prognosis of melanoma patients. The overexpression of TRIP13 promotes the invasion, migration and EMT transformation of melanoma cells in vitro, and promotes lung metastasis in vivo. Mechanismly, TRIP13 interacts with FLNA, and activates the PI3K/AKT pathway, and then induces melanoma migration, invasion and EMT transformation.Conclusion: Elevated TRIP13 drives tumor progression via the FLNA/PI3K/AKT axis, and TRIP13 is a innovative prognostic molecule and potential target of targeted therapy in melanoma.

Abstract Background: Long noncoding RNA NEAT1 has been implicated in glioma progression. However, the effect of NEAT1 on glycolysis of glioma cell and the potential mechanism remain unclear.Methods: In vitro experiments, including CCK-8, colony formation, ECAR, and lactate detection assays were performed to evaluate the effect of NEAT1 on proliferation and glycolysis of glioma cell. RNA pulldown and RIP assays were performed to identify the interaction between NEAT1 and PGK1. Truncated mutation of NEAT1 and PGK1 was used to confirm the specific interactive domains between NEAT1 and PGK1. Animal studies were performed to analyze the effect of NEAT1/PGK1 on glioma progression. Results: NEAT1 knockdown significantly suppressed the proliferation and glycolysis of glioma cells. NEAT1 could specifically interact with PGK1, which promotes PGK1 stability. Hairpin A of NEAT1 is essential for interaction with M1 domain of PGK1. Depletion of NEAT1 markedly inhibited tumor growth in mice, while PGK1 could reverse this effect. Higher expression of NEAT1 was associated with poor overall survival of GBM patients.Conclusions: NEAT1 over expression promotes glioma progression through stabilizing PGK1. NEAT1/PGK1 axis is a candidate therapeutic target for glioma treatment.

Background: Obtaining accurate prevalence rates of sexual violence is made difficult by discrepancies in self-reporting questionnaires. Thus, the current study sought to explore participants' perceptions of acceptability (i.e., perceived difficulty, readability, and preference) of questionnaires as an important psychometric indicator and a potential mechanism of discrepancy between different questionnaires assessing sexual victimization. Methods: Participants were 673 college students who completed the Sexual Experiences Survey-Short Form Victimization (SES-SFV) and the Post-Refusal Sexual Persistence Scales-Victimization (PRSPS-V). Participants then answered questions about each measure's perceived difficulty and their preference between the two. Flesch-Kincaid Reading Grade Level and efficiency (i.e., number of items: number of cases identified) were also analyzed. Results: Participants found the PRSPS-V easier to understand and preferred it 2.5 to1 over the SES-SFV. Preference was related to reporting; participants who preferred the PRSPS-V reported more instances of sexual victimization on the PRSPS-V. The PRSPS-V was objectively easier to comprehend according to Flesch-Kincaid levels and was two times more efficient than the SES-SFV in the number of cases detected per item administered. Conclusions: Our results indicate that acceptability impacts reported prevalence rates and is one mechanism for documented discrepancies between sexual violence questionnaires. Thus, it may behoove researchers to consider acceptability as a metric of interest when choosing sexual victimization questionnaires.

N6-methyladenosine (m6A) is the most common epigenetic modification of eukaryotic RNA, which can participate in the growth and development of the body and a variety of physiological and disease processes by affecting the splicing, processing, localization, transport, translation, and degradation of RNA. Increasing evidence shows that non-coding RNAs, particularly microRNA, long non-coding RNA, and circular RNA, can also regulate the RNA m6A modification process by affecting the expression of m6A-related enzymes. The interaction between m6A modification and non-coding RNAs provides a new perspective for the exploration of the potential mechanism of tumor genesis and development. In this review, we summarize the potential mechanisms and effects of m6A and non-coding RNAs in gastrointestinal tract cancers.

COVID-19 is a highly contagious respiratory disease, which mainly affects the lungs. Critically ill patients are easily complicated by cytokine storms, acute respiratory distress syndrome (ARDS), and respiratory failure, which seriously threaten their lives. Pulmonary fibrosis (PF) is a common interstitial lung disease, and its pathogenesis may involve the participation of a variety of immune cells and inflammatory factors. Current studies have shown that patients with COVID-19 may be complicated by pulmonary fibrosis, and patients with pulmonary fibrosis may also be at higher risk of contracting COVID-19 than healthy people. Pulmonary fibrosis is an important risk factor leading to the aggravation of COVID-19 disease. COVID-19 complicated by cytokine storm and ARDS mechanism pathways are similar to the pathogenesis of pulmonary fibrosis. The potential interaction between pulmonary fibrosis and COVID-19 can cause acute exacerbation of the patient’s condition, but the potential mechanism between the two has not been fully elucidated. Most of the drug treatment programs for COVID-19-related pulmonary fibrosis are currently formulated about the relevant guidelines for idiopathic pulmonary fibrosis (IPF), and there is no clear drug treatment program recommendation. This article aims to summarize the relevant mechanism pathways of COVID-19 and pulmonary fibrosis, explore the interrelationships and possible mechanisms, and discuss the value and risks of existing and potential COVID-19-related pulmonary fibrosis treatment drugs, to provide reference for anti-fibrosis treatment for patients.

Glioblastoma multiforme (GBM) is the most malignant and multiple tumors of the central nervous system. The survival rate for GBM patients is less than 15 months. We aimed to uncover the potential mechanism of GBM in tumor microenvironment and provide several candidate biomarkers for GBM prognosis. In this study, ESTIMATE analysis was used to divide the GBM patients into high and low immune or stromal score groups. Microenvironment associated genes were filtered through differential analysis. Weighted gene co-expression network analysis (WGCNA) was performed to correlate the genes and clinical traits. The candidate genes’ functions were annotated by enrichment analyses. The potential prognostic biomarkers were assessed by survival analysis. We obtained 81 immune associated differentially expressed genes (DEGs) for subsequent WGCNA analysis. Ten out of these DEGs were significantly associated with targeted molecular therapy of GBM patients. Three genes (S100A4, FCGR2B, and BIRC3) out of these genes were associated with overall survival and the independent test set testified the result. Here, we obtained three crucial genes that had good prognostic efficacy of GBM and may help to improve the prognostic prediction of GBM.
