Contrast Enhanced Endoscopic Ultrasound Imaging for Gastrointestinal Subepithelial Tumors [PDF]

Clinical Endoscopy, 2019
Subepithelial tumors are divided into benign subepithelial and potentially malignant gastrointestinal stromal tumors. It is difficult to distinguish between these tumor types.

Loss of proton‐sensing TDAG8 increases tumor progression in mouse models of colon cancer

Molecular Oncology, EarlyView.
Loss of the pH‐sensing receptor TDAG8 accelerates colorectal cancer progression in mice. Animals lacking TDAG8 expression had increased tumor growth, DNA damage, and recruitment of tumor‐associated immune cells, including macrophages, neutrophils, and monocytes.

Jejunal stromal tumor and neurofibromatosis

Journal of Coloproctology, 2019
Gastrointestinal stromal tumors, although rare, are the most common primary mesenchymal neoplasms of the gastrointestinal tract and originate from the interstitial cells of Cajal.

Mutations in ALK and TSC1 in a gastrointestinal stromal tumor: a case report

BMC Surgery, 2021
Background Gastrointestinal stromal tumors rarely occur in children, but when they do, their biological behavior and histopathological patterns differ from those of adults.

PANoptosis in the pathogenesis of myelodysplastic syndromes

Molecular Oncology, EarlyView.
PANoptosis, a combination of three types of programmed cell death, is mediated by a large protein complex called a PANoptosome. In healthy bone marrow hematopoietic cells, PANoptosis is restricted by inhibitory signaling. In MDS, bone marrow cells become sensitive to the PANoptotic stimuli due to the aberrant inactivation of inhibitory signaling or ...

A duodenal gastrointestinal stromal tumor mimicking a pancreatic neuroendocrine tumor: a case report

Journal of Medical Case Reports, 2022
Background Duodenal gastrointestinal stromal tumors are rare. If tumor growth is extraluminal and involves the head of the pancreas, the diagnosis of a duodenal gastrointestinal stromal tumor is difficult.

Cancer cell‐intrinsic type 1 interferon: production, signaling, and outcomes within sex‐biased, female malignancies

Molecular Oncology, EarlyView.
The cell‐autonomous roles of interferon type 1 vary based on duration and intensity. While acute, robust signaling results in cancer cell cytotoxic effects, sustained, low‐level signaling is associated with tumor‐promoting effects. This review summarizes current research of IFN‐1 in cancer and within the clinical setting, with an emphasis on female ...

Orai1 mediates tumor-promoting store-operated Ca entry in human gastrointestinal stromal tumors via c-KIT and the extracellular signal–regulated kinase pathway

Tumor Biology, 2017
Gastrointestinal stromal tumors originate from interstitial cells of Cajal, the pacemaker cells of the gut. Ca 2+ regulates the pacemaker activity of interstitial cells of Cajal.

Pharmacological inhibition of the PERK pathway modulates hepatocellular carcinoma growth and immune signaling

FEBS Open Bio, EarlyView.
Pharmacological inhibition of PERK in a DEN‐induced mouse model of liver cancer does not reduce tumor burden but alters cellular stress signaling. Despite blocking PERK activity, downstream stress responses, including CHOP expression, remain active, suggesting compensatory mechanisms within the unfolded protein response that may influence tumor ...

Gastric gastrointestinal stromal tumor with osseous differentiation and stromal calcification: A case report and review of literature

SAGE Open Medical Case Reports, 2017
Gastrointestinal stromal tumors are the most common primary mesenchymal tumors of the gastrointestinal tract accounting for 0.1%–3.0% of all gastrointestinal malignancies.
