Background
There were few studies assessed the postoperative sarcopenia in patients with cancers. The objective of present study was to assess whether postoperative development of sarcopenia could predict a poor prognosis in patients with adenocarcinoma of esophagogastric junction, (AEG) and upper gastric cancer (UGC).Methods
Patients with AEG and UGC who were judged as non-sarcopenic before surgery were reassessed the presence of postoperative development of sarcopenia 6 months after surgery. Patients were divided into the development group or non-development group, and clinicopathological factors and prognosis between these two groups were analyzed.Results
The 5-year overall survival rates were significantly poorer in the development group than non-development group (68.0% vs. 92.6%, P?=?0.0118). Multivariate analyses showed that postoperative development of sarcopenia was an independent prognostic factor for poor overall survival (P?=?0.0237).Conclusions
Postoperative development of sarcopenia was associated with a poor prognosis in patients with AEG and UGC. 相似文献2.

目的 研究长链非编码RNA PCED1B-AS1调控核苷酸结合寡聚化结构域样受体3(NLR family pyrindomain containing 3, NLRP3)对巨噬细胞清除结核分枝杆菌和分泌炎症因子的影响。方法 在巨噬细胞RAW264.7中转染pcDNA-PCED1B-AS1,并用结核分枝杆菌感染,qRT-PCR方法检测PCED1B-AS1和TNF-α、IL-6 mRNA水平,用菌落形成实验检测巨噬细胞对结核分枝杆菌的清除作用,Western blot方法检测细胞中NLRP3蛋白表达水平。将NLRP3 小干扰RNA(small interfering RNA, siRNA)和pcDNA-PCED1B-AS1共转染到巨噬细胞中,用结核分枝杆菌感染,同样检测细胞中TNF-α、IL-6 mRNA水平和菌落量。结果 结核分枝杆菌感染后的巨噬细胞中PCED1B-AS1水平降低,TNF-α、IL-6 mRNA水平升高。转染pcDNA-PCED1B-AS1后的巨噬细胞经过结核分枝杆菌感染以后,细胞中PCED1B-AS1、TNF-α、IL-6 mRNA水平升高,形成的菌落量减少,细胞中NLRP3蛋白表达水平升高。NLRP3 siRNA可以逆转过表达PCED1B-AS1对结核分枝杆菌感染的巨噬细胞中TNF-α、IL-6 mRNA表达和菌落量形成的影响。结论 上调PCED1B-AS1促进巨噬细胞清除结核分枝杆菌,诱导细胞表达TNF-α、IL-6 mRNA的机制与上调NLRP3表达有关。 相似文献

BackgroundHepatocellular carcinomas (HCCs) occur frequently in the digestive system and are associated with high mortality. This current study examined the regulatory relationship between interleukin (IL)-1 receptor-associated kinase 1 (IRAK1), NLR family pyrin domain-containing 3 (NLRP3) inflammasomes, and tumor-associated macrophages (TAMs) in the growth and metastasis of HCC.MethodsThe expression of IRAK1 and NLRP3 was assessed in tissues and cells via quantitative real-time polymerase chain reaction (qRT-PCR) and Western blot analysis. Immunohistology was performed to detect the macrophage markers CD68, CD163, and CD168 in tumor tissues. Small interfering (si)RNA targeting IRAK1 (si-IRAK1) was designed to silence IRAK1 expression. Following si-IRAK1 transfection and/or co-culture with TAMs, HCC cell viability, proliferation, migration, and invasion, as well as the expression of NLRP3 and pro-inflammatory cytokines IL-1 β, IL-18, and monocyte chemotactic protein 1 (MCP-1) were assessed.ResultsHCC tissues showed elevated expression of IRAK1 and NLRP3, as well as increased expression of the macrophage markers CD68, CD163, and CD168, compared to adjacent healthy tissues. Silencing of IRAK1 expression in HepG2 and Huh7 cells resulted in suppression of cell proliferation, migration, and invasion, and also reduced expression of NLRP3 and the pro-inflammatory cytokines IL-1β, IL-18, and MCP-1. Moreover, TAMs promoted HepG2 and Huh7 cell proliferation, migration, and invasion, and elevated the expression of NLRP3, IL-1β, IL-18, and MCP-1. Furthermore, IRAK1 silencing reversed the effects of TAMs on HepG2 and Huh7 cells.ConclusionsThe expression of IRAK1 was associated with HCC growth and metastasis, as well as NLRP3 inflammasome activation. The ability of TAMs to promote HCC growth and metastasis may be activated by NLRP3 inflammasomes and regulated by IRAK1. 相似文献

Aging is by far the most prominent risk factor for Alzheimer's disease (AD), and both aging and AD are associated with apparent metabolic alterations. As developing effective therapeutic interventions to treat AD is clearly in urgent need, the impact of modulating whole-body and intracellular metabolism in preclinical models and in human patients, on disease pathogenesis, have been explored. There is also an increasing awareness of differential risk and potential targeting strategies related to biological sex, microbiome, and circadian regulation. As a major part of intracellular metabolism, mitochondrial bioenergetics, mitochondrial quality-control mechanisms, and mitochondria-linked inflammatory responses have been considered for AD therapeutic interventions. This review summarizes and highlights these efforts. 相似文献
