Warburg effect reflects that tumor cells tend to generate energy by aerobic glycolysis rather than oxidative phosphorylation (OXPHOS), thus promoting the development of malignant tumors. As a kind of non-coding RNA, circular RNA (circRNA) is characterized by a closed ring structure and emerges as a regulator of cancer metabolism. Mounting studies revealed that circRNA can regulate the cancer metabolism process through affecting the expression of glycolysis relevant enzymes, transcription factors (TFs), and signaling pathways. In this review, we comprehensively analyzed and concluded the mechanism of circRNA regulating glycolysis, hoping to deepen the cognition of the cancer metabolic regulatory network and to reap huge fruits in targeted cancer treatment.

This bioinformatic study confirmed a new miRNA-mRNA regulatory network and a prognostic signature in endometrial cancer (EC).

We downloaded RNA-seq and miRNA-seq data of EC from the TCGA database, then used EdegR package to screen differentially expressed miRNAs and mRNAs (DE-miRNAs and DE-mRNAs). Then, we constructed a regulatory network of EC-associated miRNAs and hub genes by Cytoscape, and determined the expression of unexplored miRNAs in EC tissues and normal adjacent tissues by quantitative Real-Time PCR (qRT-PCR). A prognostic signature model and a predictive nomogram were constructed. Finally, we explored the association between the prognostic model and the immune cell infiltration.

A total of 11,531 DE-mRNAs and 236 DE-miRNAs, as well as 275 and 118 candidate DEGs for upregulated and downregulated DE-miRNAs were screened out. The miRNA-mRNA network included 5 downregulated and 13 upregulated DE-miRNAs. qRT-PCR proved that the expression levels of miRNA-18a-5p, miRNA-18b-5p, miRNA-449c-5p and miRNA-1224-5p and their target genes (NR3C1, CTGF, MYC, and TNS1) were consistent with our predictions. Univariate and multivariate Cox proportional hazards regression analyses of the hub genes revealed a significant prognostic value of NR3C1, EZH2, AND GATA4, and these genes were closely related to eight types of immune infiltration cells.

We identified three genes as candidate biomarkers for EC, which may provide a theoretical basis for targeted therapy.

Recently, the British Myeloma Research Alliance put forward a Myeloma Risk Profile (MRP) for the first time to stratify the prognosis risk of non-transplanted patients with multiple myeloma. However, only limited studies have evaluated the applicability of this model in the Chinese population. This study aimed to estimate the prognostic value of MRP in newly diagnosed multiple myeloma patients without autologous stem cell transplantation in China.

Patients with multiple myeloma in Wuxi People's Hospital from January 1, 2007, to June 30, 2018 were evaluated based on the MRP score, and the relationship between the clinical outcome of patients with MM and the score was analyzed retrospectively.

First, significant differences were observed in the overall survival (OS) (P<0.05) and progression-free survival (PFS) (P<0.05) between the low-, middle-, and high-risk groups. Second, in the bortezomib treatment subgroup and complex chromosome karyotype subgroup, OS and PFS were significantly shorter in the high-risk group than in the low-risk group (P<0.05). Third, the depth of remission still showed prognostic significance in the high-risk MRP group.

MRP is also applicable in Chinese patients with newly diagnosed MM who did not undergo transplantation, as it is simple and cost effective; hence, it is worth popularizing.

Papillary thyroid cancer (PTC) patients could obtain poor prognosis if they have lymph node metastasis, identification of informative and robust biomarkers for predicting cervical lymph node metastasis is critical for improving clinical decision-making and patient prognosis.

In this study, we analyzed the expression of X box binding protein 1 spliced-form (XBP1s) in 41 PTC tissue samples and extended our findings using public databases, then we investigated how XBP1s' contributed to PTC progression in vitro.

We found that XBP1s' expression was lower in PTC patients with cervical lymph node metastasis than non-metastasis patients by immunohistochemical analysis. With publicly accessible dataset, we showed that the XBP1 transcription was significantly decreased in thyroid cancer (TC) tissues with lymph node metastasis as compared to that without lymph node metastasis. Moreover, we also found that XBP1 expression was significantly correlated with patients' gender, T classification, lymph node metastasis and PTC stages, and low XBP1 expression was associated with poor diseases free survival (DFS). In vitro, XBP1s overexpression could inhibit the invasion, migration, and wound healing capacity of PTC cells. Mechanistically, overexpression of XBP1s could enhance the expression of classical epithelial-mesenchymal transition (EMT) markers such as ZO-1 and E-cadherins, and downregulated N-cadherin in BCPAP cells.

These findings suggest that XBP1s is a prognostic maker for thyroid carcinoma patients, and sustaining XBP1s expression might be a new strategy to control PTC progression.

Certain nutrients have shown protective effects against frailty, but less is known about the influence of individual food groups. Thus, this study aimed to investigate the relationship between the intake of different food groups and physical frailty in a cohort of community-dwelling older adults in Cork, Ireland.

One hundred and forty-two (n = 81 females, n = 61 males, age 74.1 ± 6.80 years) Irish community-dwelling volunteers aged ⩾65 years participated in this cross-sectional study. Dietary intake was assessed using a validated food frequency questionnaire (FFQ). MAPK inhibitor Frailty was identified as having 3 or more of the following criteria weight loss, exhaustion, weakness, slow walking speed and low physical activity. Relationships between intakes of food groups and frailty score were determined using Spearman's rank (and partial rank) correlations and ordinal logistic regression analysis.

Negative Spearman's rank correlations were observed between frailty score and fish and fish products, fruit and vegetables and nuts and seeds, while positive correlations were found between frailty score and potatoes, fats and oils and sugars, preserves and snacks (
