Members of microRNA(miR)-200 family is proposed as promising biomarkers for colorectal cancer (CRC). However, their expression in CRC patients, and whether them could identify as new biomarkers of cancers are inconsistent and controversy. Therefore, a meta-analysis was performed to assess the diagnostic value of miR-200 family members in CRC patients. This meta-analysis screened 6 studies, including 191 patients with colorectal cancer at stage IV, 446 patients with colorectal cancer at stage I~III and 98 normal controls, and performed using bivariate and hierarchical summary receiver operating characteristic (HSROC) models. The quality of the eligible studies was assessed according to Quality Assessment of Diagnosis Accuracy Studies-2. The pooled sensitivity and specificity of miR‑141 alone for CRC diagnosis were 82% and 75%, respectively. The diagnostic odds ratio (DOR) value was 13.21 [95% confidence interval (CI), 7.00‑24.95], and the area under the curve (AUC) was 0.85 (95% CI, 0.82‑0.88). The pooled sensitivity and specificity of total miR-200 family members were 79% and 71%, respectively. In the HSROC model, the estimate for the "Lambda" was 2.48 (95% CI,1.50-3.46). Finally, we detected the miR-141 in 20 CRC patients and 20 healthy. Results showed that serum miR-141 was overexpressed in CRC patients. Overall, miR-141 in miR-200 family has a good sensitivity and moderate specificity for CRC diagnosis.

Purpose: The aim of this study was to assess how pandemic-related health concerns and discrimination affected cancer screenings among Asian American women (AAW).
Methods: A two-phase explanatory mixed-methods study was conducted. In phase 1, a survey was distributed among AAW eligible for lung, breast, or colorectal cancer screening to assess delays during the pandemic, concerns about contracting coronavirus disease 2019 (COVID-19), barriers to care, and experiences of discrimination.

Rak jelita grubego (RJG) jest jednym z najczęściej rozpoznawanych nowotworów złośliwych: co roku notowane jest około 1,9 miliona nowych przypadków. Pomimo opracowania metod umożliwiających jego wykrywanie na początkowym etapie choroby i wprowadzenia nowych, skuteczniejszych terapii, RJG plasuje się na drugim miejscu wśród przyczyn zgonów wywołanych nowotworami. Wyniki najnowszych badań podkreślają rolę transporterów kwasów tłuszczowych, tj.

Recently, we demonstrated that the oncolytic Coxsackievirus B3 (CVB3) strain PD-H can be efficiently adapted to resistant colorectal cancer cells through dose-dependent passaging in colorectal cancer cells. However, the method is time-consuming, which limits its clinical applicability. Here, we investigated whether the manufacturing time of the adapted virus can be reduced by replacing the dose-based passaging with volume-based passaging.

Background/objectives: Colorectal cancer (CRC) is characterized by a high rate of both incidence and mortality, and its treatment outcomes are often affected by recurrence and drug resistance. Ferroptosis, an iron-dependent programmed cell death mechanism triggered by lipid peroxidation, has recently gained attention as a potential therapeutic target. Graphene oxide (GO), known for its oxygen-containing functional groups, biocompatibility, and potential for functionalization, holds promise in cancer treatment.

Background/objectives: KRT23 was recently discovered as an epithelial-specific intermediate filament protein in the type I keratin family. Many studies have underlined keratin's involvement in several biological processes as well as in the pathogenesis of different diseases. Specifically, KRT23 was reported to affect the structural integrity of epithelial cells and to trigger cellular signaling leading to the onset of cancer.
