RESUMO

OBJECTIVES: The interferon regulatory factor (IRF) family of proteins are involved in tumor progression. However, the role of IRF5 in tumorigenesis remains unknown. In this study we aimed to elucidate the functions of IRF5 in the progression of hepatocellular carcinoma (HCC). METHODS: IRF5 expression in HCC was analyzed through quantitative polymerase chain reaction (qPCR), western blot, and immunohistochemistry (IHC), etc. The Cell Counting Kit 8 (CCK8) assay, anchorage-independent assay, and EdU assay were used to evaluate the role of IRF5. The molecular mechanisms were studied by analyzing the metabolites with mass spectrum and immunoprecipitation. RESULTS: IRF5 was upregulated in HCC. Interfering with IRF5 inhibited the proliferation and tumorigenic potential of HCC cells. When studying the molecular mechanism, IRF5 was found to upregulate the expression of lactate dehydrogenase A (LDHA) and promoted glycolysis. Additionally, tripartite motif containing 35 (TRIM35) interacted with IRF5, promoting its ubiquitination and degradation. In the clinically obtained HCC samples, TRIM35 was negatively correlated with the expression of IRF5. CONCLUSION: These findings reveal the oncogenic function of IRF5 in the progression of HCC by enhancing glycolysis, further supporting the potential of IRF5 as a viable target for HCC therapy.

RESUMO

BACKGROUND: Motoric Cognitive Risk syndrome (MCR), known as the predementia stage, is characterized by both subjective cognitive complaint (SCC) and slow gait. This study aimed to investigate the causal relationship between MCR, its components, and falls. METHODS: Participants aged ≥ 60 years were selected from China Health and Retirement Longitudinal Study. SCC was determined by participants' responses to the question "How would you rate your memory at present?" with "poor" being the indicative answer. Slow gait was defined as one standard deviation or more below age- and gender-appropriate mean values of gait speed. MCR was identified when both SCC and slow gait were presented. Future falls were investigated by the question "have you fallen down during follow-up until wave 4 in 2018?" Logistic regression analysis was performed to test the longitudinal association of MCR, its components and future falls during the following 3 years. RESULTS: Of 3748 samples in this study, the prevalence of MCR, SCC, and slow gait was 5.92%, 33.06%, and 15.21%, respectively. MCR increased the risk of falls during the following 3 years by 66.7% compared to non-MCR after controlling for covariates. In the fully adjusted models, with the healthy group as reference, MCR (OR = 1.519, 95%CI = 1.086-2.126) and SCC (OR = 1.241, 95%CI = 1.018-1.513), but not slow gait, increased the risk of future falls. CONCLUSIONS: MCR independently predicts future falls risk in the following 3 years. Measuring MCR can be a pragmatic tool for early identification of falls risk.

RESUMO

Symptoms that are multidimensional and concurrent should be assessed from different dimensions and managed together. Few studies have evaluated concurrent and multidimensional symptoms in patients with stroke. Most studies of stroke focused on dysfunctions and complications. We hypothesize that patients with stroke have a heavy symptom burden within 1 year. This study aimed to describe multidimensional and concurrent symptoms within 1 year after stroke. This study recruited 230 patients with stroke from the Rehabilitation Department of Xuhui District Center Hospital of Shanghai and the Shanghai Sunshine Rehabilitation Center in China from March to September 2017. The patients' multidimensional symptom experience and symptom burden were analyzed using a self-made structured questionnaire and the influential factors for symptom burden were identified. The mean number of symptoms in patients with stroke was 11.7 ± 3.5. More than two thirds of the participants suffered from at least 10 co-occurring symptoms. Unilateral limb weakness had the highest prevalence and frequency. Participation restriction had the highest symptom dimensions of severity and distress. Lack of self-care ability (severity), memory deterioration (frequency), imbalance of body (distress), moodiness (distress), being unable to move limbs at will (distress), shoulder pain (distress), and slower response (frequency) were independent factors of the total symptom burden score. These findings can provide essential information for efficient symptom management of patients with stroke. This trial was registered with the ISRCTN registry (registration number: ISRCTN18421629).
