This study tested the hypothesis that combined therapy with probiotics and cytokine-induced killer (CIK) cells was superior to merely one on suppressing the peritoneal carcinomatosis and liver metastasis of colorectal cancer (CRC) cells in nude mice. The study revealed that in HCT 116/SW620 CRC cell lines, cell viability, proliferation, colony formation, migratory ability, wound healing, and protein expression of PD-L1 and FAK were significantly and comparably suppressed and that apoptosis was significantly and comparably increased by probiotics and CIK cells, and these effects were further significantly enhanced by combined probiotics + CIK cell therapy (all p<0.001).

Background/aim: Patients diagnosed with advanced metastatic colorectal cancer (CRC) confront a bleak prognosis characterized by low survival rates. Anoikis, the programmed apoptosis resistance exhibited by metastatic cancer cells, is a crucial factor in this scenario.
Materials And Methods: We employed bulk flow cytometry and RT-qPCR assays, conducted in vivo experiments with mice and zebrafish, and analyzed patient tissues to examine the effects of the B cell-specific Moloney murine leukemia virus insertion site 1 (Bmi1)-midkine (MDK) axis on the cellular response to anoikis.
Aims: Colorectal cancer (CRC) remains a major global health issue, with metastatic cases presenting poor prognosis despite advances in chemotherapy and targeted therapy. Irinotecan, a key drug for advanced CRC treatment, faces challenges owing to the development of resistance. This study aimed to understand the mechanisms underlying irinotecan resistance in colorectal cancer.

Four positive lymph nodes are typically considered an indicator to assess disease spread and patient prognosis. However, the subjective counting of positive axillary lymph nodes underscores the need for biomarkers to improve diagnostic precision and reduce the risk of unnecessary treatments.

SUV39H1-mediated epigenetic regulation is associated with cancer cell migration, invasion, metastasis, and treatment resistance. This study aims to identify the role of SUV39H1 in TNBCs.
View Article and Find Full Text PDFTriple-negative breast cancer (TNBC) is characterized by the loss of expression of several biomarkers, which limits treatment strategies for the disease. In recent years, immunotherapy has shown promising results in the treatment of various tumors. Emerging evidence demonstrated that TNBC is an immune-activated cancer, suggesting that immunotherapy could be a feasible treatment option for TNBC.

Surgical intervention, along with chemotherapy or radiation therapy, is the mainstay of treatment. Currently, precision medicine has led to personalized treatment using reliable biomarkers for the heterogeneity of breast cancer.

Despite multidisciplinary involvement in interventions involving surgery, radiotherapy, and chemotherapy, most pancreatic cancer patients eventually develop distant metastasis. S-phase kinase-associated protein 2 (Skp2) plays an important role in cell-cycle regulation in pancreatic cancer.

Lymphangioma in small intestine sometimes caused unspecific symptoms and even bleeding, however, this area was most difficult for endoscopic examination and worth investigation.
Methods: From 1999 to 2019, we retrospectively collected eighteen adult patients with the pathological diagnosis of lymphangioma from duodenum to terminal ileum.
Inorganic arsenic (iAs), a known human carcinogen, induces oxidative DNA damage and epigenetic silencing of tumor suppressor genes related to tumor progression. Chromodomain-helicase-DNA-binding protein 4 (CHD4) is a chromatin remodeling protein that acts on DNA repair and DNA methylation under oxidative damage in malignancies, but the role of CHD4 in arsenical urothelial carcinoma (UC) is unidentified. Our purpose was to observe CHD4-related repair effects on As-stimulated oxidative damage in human UC.

Many metabolic pathways and nutrient uptake systems are frequently reprogrammed and upregulated to meet the demand from cancer cells, including the demand for lipids. The lipids for most adult normal cells are mainly acquired from the circulatory system.

Preclinical and clinical trials targeting post-translational modifications have been evaluated as monotherapy or in combination with standard chemotherapy. In this study, we selected 43 genes from seven families of chromatin-modifying enzymes and investigated the influences of epigenetic modifications and their interactions on pancreatic ductal adenocarcinoma (PDAC) using hierarchical clustering analysis.

However, the post-market study IMpassion131 did not support the original observation, resulting in the voluntary withdrawal of atezolizumab from the indication in breast cancer by Genentech in 2021. Emerging evidence has revealed a high frequency of false negative result using the standard immunohistochemical (IHC) staining due to heavy glycosylation of PD-L1.
View Article and Find Full Text PDFTriple-negative breast cancer (TNBC) remains a significant clinical challenge because of its high vascularity and metastatic and recurrent rates. Tumor angiogenesis is considered an important mediator in the regulation of tumor cell survival and metastasis in TNBC. Angiogenesis is induced by the binding of vascular endothelial growth factor to vascular endothelial growth factor receptor 2 (VEGFR2).
View Article and Find Full Text PDFTriple-negative breast cancer (TNBC) is the most aggressive breast cancer subtype and exhibits an overall poor outcome. Due to the lack of targeted therapy, conventional systemic chemotherapy has been the main strategy for the treatment of TNBC. Further evidence has shown that combining radiation with chemotherapy is also a suitable treatment based on DNA repair deficiencies in patients with TNBC.

Surgical resection combined with chemo-, radio-, or targeted-therapies are the main treatments for CRC patients in current clinical practice. However, many CRC patients still respond poorly to these treatments, leading to tumor recurrence and an unacceptably high incidence of metastasis and death.

View Article and Find Full Text PDFTriple-negative breast cancer (TNBC) has high metastatic, drug-resistance, and recurrence rates, and is characterized by an angiogenic and fibrotic microenvironment that favors cancer malignancy. However, details of the mechanisms underlying malignancy are still largely unknown. Our mouse model indicated that knockdown of CDK6 inhibited lung metastasis significantly compared to parental cells.

Objectives: Many surgeons develop unique techniques for unmet needs for right ventricular outflow reconstruction to resolve pulmonary regurgitation after corrective surgery for congenital heart diseases. Expanded polytetrafluoroethylene (ePTFE) stands out as a reliable synthetic material, and clinical results with handmade ePTFE valves have been promising. This review focuses on the historical evolution of the use of ePTFE in pulmonary valve replacement and in the techniques for pioneering the translation of the handmade ePTFE trileaflet design for the transcatheter approach.
