Expression, Prognostic Value, and Immune Infiltration of MTHFD Family in Bladder Cancer.

BACKGROUND: The Methylenetetrahydrofolate Dehydrogenase (MTHFD) family plays an important role in the development and prognosis of a variety of tumors; however, the role of the MTHFD family in bladder cancer is unclear. METHODS: R software, cBioPortal, GeneMANIA, and online sites such as String-LinkedOmics were used for bioinformatics analysis. RESULTS: MTHFD1/1L/2 was significantly upregulated in bladder cancer tissues compared with normal tissues, high expression of the MTHFD family was strongly associated with poorer clinical grading and staging, and bladder cancer patients with upregulated expression of MTHFD1L/2 had a significantly worse prognosis. Gene function and PPI network analysis revealed that the MTHFD family and related genes play synergistic roles in the development of bladder cancer. 800 co-expressed genes related to the MTHFD family were used for functional enrichment analysis, and the results showed that many genes were associated with various oncogenic pathways such as cell cycle and DNA replication. More importantly, the MTHFD family was closely associated with multiple infiltrating immune lymphocytes, including Treg cells, and immune molecules such as TNFSF9, CD274, and PDCD1. CONCLUSION: Our study shows that MTHFD family genes may be potential prognostic markers and therapeutic targets for patients with bladder cancer.

Incidence, Prognostic Factors, and Survival of Patients with Renal Cancer: A Population-Based Study.

BACKGROUND: The main objective of this article is to understand trends in the incidence of renal cancer and to construct a nomogram to predict the prognosis of patients with renal cancer by analyzing clinical parameters. METHODS: We extracted data from the Surveillance, Epidemiology and End Results (SEER) database for patients with renal cancer from 2010 to 2015. The incidence rate was calculated to understand the trend of renal cancer in recent years, and the Kaplan-Meier method was used to analyze the relationship between patients' clinical variables and overall survival. Nomogram and calibration curves were constructed based on factors predicted by multivariate Cox regression. RESULTS: Data from 68,496 eligible renal cancer patients were included in the study. The incidence of renal cancer was higher in men than women and tended to stabilize over time. We further found that age, gender, marital status, AJCC stage, histological type, metastatic disease, and surgery were independent parameters for prognosis in renal cancer patients. Finally, a nomogram was constructed based on the above parameters, and its validity was verified with the agreement index and calibration curve. CONCLUSION: Renal cancer incidence trend gradually stabilized. Seven independent parameters for renal cancer patients were obtained by analysis and utilized to construct a nomogram that could provide guidance for clinical practice.

Interaction of cobalt(II) and nickel(II) with a gamma-linked, bis-beta-diketone ligand to yield an unusual coordination motif.

Discrete cobalt(II) and nickel(II) complexes of type ML (where L is a bis(2,4-pentanedionate) derivative incorporating a -SCH2CH2S- bridge between the gamma-carbons of respective beta-diketone units) have been synthesised and represent the first examples in which a gamma-substituted, thioether-containing beta-diketone ligand coordinates via a sulfur and oxygen donor in preference to the classical coordination mode involving both beta-diketonate oxygens.
