Gut microbes as cancer drivers: New multi‑omics review unmasks their hidden role in colorectal cancer

China Anti-Cancer Association

The gut microbiome is not a mere spectator but an active player in colorectal cancer (CRC), driving tumor initiation and progression through direct bacterial attacks, metabolite signals, and genetic manipulation.

Weakly supervised teacher–student framework with progressive pseudo-mask refinement for gland segmentation

Xia & He Publishing Inc.

Colorectal cancer histopathological grading relies on the accurate segmentation of glandular structures. Current deep learning–based methods depend heavily on large-scale pixel-level annotations that are labor-intensive and not amenable to clinical practice. Weakly supervised semantic segmentation offers a promising alternative; yet, existing class activation map–based weakly supervised semantic segmentation approaches often produce incomplete, low-quality pseudo-masks that overemphasize discriminative regions and fail to provide reliable supervision for unannotated glandular structures, limiting their suitability for dense histopathology segmentation under sparse supervision. We propose a novel weakly supervised teacher–student framework that leverages sparse pathologists’ annotations and an Exponential Moving Average–stabilized teacher network to generate refined pseudo-masks.

Large-scale microbiome study identifies robust colorectal cancer signature

European Molecular Biology Laboratory
Peer-Reviewed Publication

Researchers from EMBL, LUMC, and collaborators reanalysed nearly 6,800 gut microbiome profiles in colorectal cancer patients and controls.

One of the largest single-disease gut microbiome meta-analyses to date, the new study identified a robust colorectal cancer microbiome signature that was consistent across populations, sequencing methods, and age-of-onset groups.

A machine-learning classifier could distinguish colorectal cancer from non-cancer microbiomes across datasets.

The colorectal cancer microbiome signature was linked to lower dietary fibre intake and could be reduced through fibre-focused dietary interventions.

Right versus left: Colorectal cancer's two microbial worlds

China Anti-Cancer Association
Peer-Reviewed Publication

The microbial landscape of colorectal cancer is far more complex than previously thought, with tumors on opposite sides of the colon harboring distinctly different bacterial communities.

EF-YOLO: A novel AI model for high-precision detection of colorectal polyps

HEP Data Cooperation Journals

Researchers from Donghua University and Yanshan University have developed an enhanced neural network called EF-YOLO, which significantly improves the automated detection of colorectal polyps—a key precursor to colorectal cancer. By integrating advanced modules such as transformer, deformable convolution, coordinate attention, and a newly designed multi-scale aggregation mechanism, the model achieves a mean average precision (mAP) of 96.60% on standard medical datasets. This represents a major step forward in reducing missed detections during colonoscopy and supporting early clinical intervention.

Scientists uncover a genetic "shield" that lowers the risk of colorectal cancer

Wayne State University - Office of the Vice President for Research
Peer-Reviewed Publication

A team of scientists from the Barbara Ann Karmanos Cancer Institute, Wayne State University, and institutions across the U.S., have published a landmark paper on the role of TGFBR1*6A, a naturally occurring genetic mutation in the TGFBR1 gene found in approximately 14 percent of the general population.

m6A RNA modification in colorectal cancer: Regulatory roles, oncogenic signaling, and metabolic pathways

Xia & He Publishing Inc.
Peer-Reviewed Publication

N6‑methyladenosine (m6A) is the most prevalent internal RNA modification, dynamically regulating RNA metabolism and cancer biology. In colorectal cancer (CRC), dysregulated m6A controls tumor growth, metastasis, immune evasion, and therapy resistance. This review integrates evidence on m6A machinery, its coordination with oncogenic signaling (Wnt/β‑catenin, PI3K/Akt, MAPK, p53) and metabolic pathways (glucose, amino acid, lipid), and translational implications. Key regulators include writers (METTL3, METTL14), erasers (FTO, ALKBH5), and readers (YTHDF, IGF2BP families). m6A‑dependent regulation of metabolic enzymes (HK2, PKM2, FASN) links epitranscriptomics to bioenergetic adaptation, positioning m6A as a central hub integrating signaling and metabolism for potential biomarker and targeted therapy development.
