Synergistic anti-tumour effects of Clostridium butyricum in combination with apatinib in CT26 colorectal tumour-bearing mice

To investigate the synergistic antitumour effect of Clostridium butyricum combined with apatinib on colorectal cancer in mice. Murine colorectal carcinoma cell line CT26.WT cells were xenografted into the skin of BALB/c mice. Tumour-bearing mice were randomly divided into four groups, and given different treatment options (PBS control; C. butyricum; apatinib; C. butyricum + apatinib). Real-time PCR was used to detect C. butyricum content in the intestine of mice given C. butyricum. The effects of various regimens on tumour growth were monitored, and CD31, proliferating cell nuclear antigen (PCNA), Bcl-2 and cleaved caspase-3 expressions in tumour were analysed by immunohistochemistry. C. butyricum combined with apatinib significantly inhibits tumour growth with decreased CD31, PCNA and Bcl-2 expressions, and increased cleaved caspase-3 expressions. Our study confirms that C. butyricum combined with apatinib in the treatment of xenografted colon tumour in mice can significantly inhibit tumour growth and promote cell apoptosis than apatinib alone treatments, providing the reference for clinical treatments.

Abstract14 new naphthoquinones were prepared and tested against human cancer cell lines PC-3 (prostate), HCT-116 (colon carcinoma), SNB-19 (glioblastoma), HL-60 (leukemia) and MCF-7 (breast), and a nontumor cell line L929 (murine fibroblasts) to determine cytotoxicity with the MTT assay. 8-OH- β-lapachones (14a,14c,14d) presented best results, showing low IC50 values and high selectivity for HCT-116 and HL-60 tumor cells.

SUMMARY: The use of transoral sonography–guided fine-needle aspiration for intraoperative localization of retropharyngeal masses has been described by Fornage et al. The purpose of this study was to assess the accuracy of this technique. We reviewed the images and medical records of 26 patients with a retropharyngeal lesion suspicious for a metastatic lymph node of Rouviere identified on CT and/or PET/CT. There were 14 patients with a history of thyroid cancer, 7 with mucosal squamous cell carcinoma, 1 with renal cell carcinoma, 1 with parotid acinic cell cancer, 1 with metastatic colon adenocarcinoma, and 2 with no ...

Authors: Modi A, Dwivedi S, Roy D, Khokhar M, Purohit P, Vishnoi J, Pareek P, Sharma S, Sharma P, Misra S Abstract Growth differentiation factor-15 (GDF-15) is a novel cytokine secreted by a variety of cells like macrophages, adipocytes, normally expressed in high amounts by placenta. It is also highly expressed in multiple carcinomas like Colon, Breast, Pancreas, Liver, and Ovarian. Several reports on serum GDF-15 as a potential biomarker for diagnosis and prognosis of cancer are hampered by the lack of robust data, with large sample size and critical patient recruitment. However, experimental accounts on cancer t...

Conclusions: Our results suggest that transcriptional patterns are indicative for TMM pathway activation with subtle differences between TEL and ALT mechanisms in a CRC subtype-specific fashion. Sequencing data potentially provide a suited measure to study alterations of telomere length and of underlying transcriptional regulation. Further studies are needed to improve this method.

The aim of this study was to evaluate the inhibitory effect of a cocktail of five Lactobacillus species on human colorectal carcinoma cell line HT-29. The anti-proliferative and apoptotic effects of Lactobacilli cocktail were evaluated using MTT and flow cytometry tests, respectively. Quantitative real-t...

In this study, we explored the mechanism of 5-FU resistance by bioinformatics analysis of the NCBI public dataset series GSE81005. Fifteen hub genes were screened out of 582 different expressed genes. Modules of the hub genes in protein-protein interaction networks gathered to TOP2α showed a decrease in HCT-8 cells but an increase in 5-FU-resistant HCT-8/5-FU cells with 5-FU exposure. Downregulation of TOP2α with siRNA or miR-494 transfection resulted in an increase of cytotoxicity and decrease of cell colonies to 5-FU for HCT-8/5-FU cells. Moreover, we found that an ethanol extract of Spica Prunellae (E...

CONCLUSIONS: The identification of V600E BRAF mutations in high grade colon neuroendocrine carcinomas has allowed the description of radiological responses to combination therapy of BRAF and MEK inhibitors in basket clinical trials. However, the molecular rationale for this treatment combination was based on the presence of the BRAF mutation and the efficacy observed in other cancer types such as melanoma. Future drug development in this setting should test BRAF inhibitors upfront and the addition of anti-EGFR antibodies instead of MEK inhibitors for an efficient blockade of acquired resistance.
