Neuron‐Derived MIF Engages VCAM1 to Fuel a Self‐Amplifying CXCL8 Loop That Drives Perineural Invasion and Metastasis in Gastric Cancer

Advanced Science, EarlyView.
Neuron‐derived MIF binds VCAM1 on gastric cancer cells and activates ERK/STAT3 signaling, leading to CXCL8 transcription and secretion. Tumor‐derived CXCL8 subsequently stimulates neuronal CXCR2 to enhance MIF production, establishing a self‐amplifying MIF–VCAM1–CXCL8 positive‐feedback loop that promotes perineural invasion, tumor progression, and ...

RBM12 Maintains Glioma Stem Cells by Activating Amino Acid‐Dependent mTORC1 Signaling via SLC7A5 mRNA Stabilization

Advanced Science, EarlyView.
This study shows that in glioma stem cells (GSCs), RBM12 recruits ALKBH5 to remove m6A from SLC7A5 transcripts, thereby enhancing mRNA stability, which elevates large neutral amino acid (LNAA) levels and activates mTORC1, promoting GSC proliferation, self‐renewal, and tumor growth.

Single‐Cell Profiling Identifies SLC2A5‐Mediated Fructose Metabolism as a Vulnerability in Primary CNS Lymphoma

Advanced Science, EarlyView.
Glucose deprivation in the primary CNS lymphoma (PCNSL) tumor microenvironment drives SLC2A5 (encoding GLUT5)‐dependent fructose metabolism in tumor cells, while hypoxia induces HIF‐mediated SLC2A5 expression in tumor‐supportive macrophages, revealing SLC2A5‐driven fructose utilization as a shared and targetable metabolic vulnerability across malignant

Self‐Sustaining Lactate Depletion Nanoplatform Remodels Tumor Microenvironment and Augments Synergistic Photodynamic/Photothermal/Chemodynamic/Starvation Therapy for Eradication of Colon Cancer

Advanced Science, EarlyView.
The HILA nanoplatform integrates HMnO2, LOX, and ICG to orchestrate multimodal therapy (starvation, chemodynamic, photodynamic, and photothermal) for achieving efficient colon cancer eradication. The established HMnO2‐LOX catalytic cycle continuously consumes lactate, acidifys microenvironment, relieves hypoxia, and generats reactive oxygen species ...

The Importance of the Macroscopic Classification of Colorectal Neoplasms

Gastrointestinal Endoscopy Clinics of North America, 2010
The importance and prevalence of the superficial lesions in the colon and rectum caught worldwide public attention in 2008 when Soetikno and colleagues reported the prevalence of non-polypoid (flat and depressed) colorectal neoplasms in asymptomatic and symptomatic adults in North America and the public media disseminated their findings.

Nonprotruding Colorectal Neoplasms: Epidemiologic Viewpoint

World Journal of Surgery, 2000
AbstractHistologic sections from 781 nonprotruding colorectal neoplasias (adenomas and early carcinomas) recorded in Sweden and in Japan were reviewed by the same observer, using strict histologic criteria. Low grade dysplasia (LGD) was present in 82.8% (299/361) of the nonprotruding neoplasms recorded in Sweden but in only 42.6% (179/420) of those ...

Colorectal neoplasm and acromegaly

Pituitary, 2006
The risk for colorectal carcinoma in acromegaly remains controversial. In our earlier study, we have demonstrated that the risk of colorectal carcinoma in Asian Indians with acromegaly is not increased and after this report, routine colonoscopy in our patients with acromegaly was abandoned.

Atypical Colorectal Neoplasms

Surgical Clinics of North America, 2017
Primary colorectal lymphoma, carcinoids (neuroendocrine tumors), and gastrointestinal stromal tumors comprise a small subset of all colorectal cancers. Their features are unique, and their treatment varies from that of colorectal adenocarcinoma. Appropriate identification is key in the management of these tumors.

Colorectal Neoplasms

Postgraduate medicine
Abstract Colorectal cancer (CRC) is primarily a disease of urban, industrialized societies. In the US, the lifetime risk of CRC is similar for men (4.4%) and women (4.1%). Recent data have suggested that the incidence rates of CRC may be decreasing gradually in some subgroups of the population but increasing in adults younger than 50 ...
