Serum direct SMOS-qPCR: a fast approach for miRNAs detection.

This study presents a novel method for direct amplification of multiple microRNAs (miRNAs) from serum samples using Sensitive and Multiplexed One-Step RT-qPCR (SMOS-qPCR). The technique eliminates the need for separate miRNA extraction and purification steps, offering a streamlined approach for non-invasive early disease diagnosis. We optimized reaction conditions, including serum treatment methods and PCR system volumes, to enhance interference resistance and detection sensitivity.

[Corrigendum] PRIMA‑1 induces autophagy in colorectal cancer cells through upregulation of the mTOR/AMPK‑ULK1‑Vps34 signaling cascade.

Following the publication of the above article, the authors contacted the Editorial Office to explain that the strips of β‑actin, LC3 and p62 proteins of the RKO cell line shown in Fig. 2A and B, and those of the SW620 cell line shown in Fig. 3A and B, were assembled in these figures incorrectly.

A sensitive and robust plasma-based DNA methylation panel for early detection of target gastrointestinal cancers.

Background: Target gastrointestinal cancers (GICs), encompassing esophageal cancer (EC), gastric cancer (GC), and colorectal cancer (CRC), originate within a single readily accessible luminal organ system and are diagnosable using endoscopy. However, endoscopy is an invasive procedure with low compliance and no plasma-based DNA methylation assay for the early detection of GICs.

Methods: Nine potential DNA methylation markers were identified and evaluated in tissue (n=60) and plasma (n=155) cohorts to select the most suitable markers.

PRIMA‑1 induces autophagy in colorectal cancer cells through upregulation of the mTOR/AMPK‑ULK1‑Vps34 signaling cascade.

p53‑reactivation and induction of massive apoptosis‑1, APR‑017 methylated (PRIMA‑1; APR246) targets mutant p53 to restore its wild‑type structure and function. It was previously demonstrated that PRIMA‑1 effectively inhibited the growth of colorectal cancer (CRC) cells in a p53‑independent manner, and distinctly induced apoptosis by upregulating Noxa in p53‑mutant cell lines. The present study including experiments of western blotting, acridine orange staining and transmission electron microscopy revealed that PRIMA‑1 induced autophagy in CRC cells independently of p53 status.
