Inflammatory bowel disease and prostate cancer risk: a two-sample Mendelian randomization analysis.

Background: Previous epidemiological observational studies have reported an association between inflammatory bowel disease (IBD) and prostate cancer (PCa), but the causality is inconclusive. The purpose of this study was to evaluate the causality of IBD on PCa using the mendelian randomization (MR) analysis.

Methods: We performed a two-sample MR analysis with public genome-wide association studies (GWAS) data.

RGN as a prognostic biomarker with immune infiltration and ceRNA in lung squamous cell carcinoma.

Regucalcin (RGN) is a potent inhibitory protein of calcium signaling and expresses in various tissues. However, the role of RGN in the tumor immunological microenvironment in lung squamous cell carcinoma (LUSC) remains unclear. This study identified the expression of RGN from public databases and immunohistochemistry with clinical specimen.

EpCAM as a Novel Biomarker for Survivals in Prostate Cancer Patients.

Due to the insufficient understanding of the biological mechanisms, the improvement of therapeutic effects of prostate cancer (PCa) is limited. There is an urgent need to find the molecular mechanisms and underlying PCa to improve its early diagnosis, treatment, and prognosis. The mRNA expression profiles, survival and methylation data of PRAD were downloaded from The Cancer Genome Atlas (TCGA) database.

Hispidulin inhibits proliferation, migration, and invasion by promoting autophagy via regulation of PPARγ activation in prostate cancer cells and xenograft models.

Prostate cancer (PCa) is one of the important factors of cancer deaths especially in the western countries. Hispidulin (4',5,7-trihydroxy-6-methoxyflavone) is a phenolic flavonoid compound proved to possess anticancer properties, but its effects on PCa are left to be released. The aims of this study were to investigate the effects and the relative mechanisms of Hispidulin on PCa development.

Is COVID-19 a high risk factor for lung cancer?: A protocol for systematic review and meta-analysis.

Introduction: COVID-19 has become a common threat to global human health and is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Some asymptomatic patients with early-stage lung cancer who have COVID-19 receive surgical treatment but develop severe pneumonia and other complications or even experience postoperative death, and they may have a worse prognosis compared with healthy individuals infected with COVID-19. However, there is no evidence that COVID-19 is a risk factor for lung cancer patients.

Prostate cancer: a risk factor for COVID-19 in males?: A protocol for systematic review and meta analysis.

Introduction: COVID-19 is now a global pandemic. Although there are very few studies describing the characteristics of SARS-CoV-2 infections in patients with prostate cancer, these patients are likely to be more susceptible to COVID-19 than healthy people because of their immunosuppressed state. However, there is no evidence that prostate cancer is a risk factor for COVID-19.

Anticancer effects of curcumin on nude mice bearing lung cancer A549 cell subsets SP and NSP cells.

Curcumin is a key polyphenolic curcuminoid extracted from the root of turmeric rhizome Curcuma longa Linn, which is a frequently used Chinese herb for the treatment of cancer. The aim of the present study was to investigate the mechanism of the inhibitory effects of curcumin on nude mice with lung cancer A549 cell subsets side population (SP) and non-SP (NSP) cells. BALB/c mice were subcutaneously injected with the tumor cells of A549 SP or NSP subsets consisting of 1×10 cells/l (0.

[Laboratory techniques for the diagnosis of prostate cancer: An update].

The prevalence of prostate cancer is increasing, which is one of the leading causes of malignancy-associated deaths of males. Because the early symptoms of prostate cancer are not obvious, 20% of the patients have metastasis at the time of initial diagnosis. The low rate of early diagnosis of prostate cancer has contributed to a higher mortality rate in China than in Europe and the United States.
