Thymoquinone and pentoxifylline enhance the chemotherapeutic effect of cisplatin by targeting Notch signaling pathway in mice

This study aimed to investigate implication of Notch in development and progression of solid Ehrlich carcinoma (SEC) and enhancement of anticancer effect of cisplatin (CIS) by addition of thymoquinone (TQ) and pentoxifylline (PTX) through modulation of Notch.Main methodsSEC was induced in mice as model for mammary carcinoma by s.c. injection of 1 × 106 Ehrlich cells into back of the mice. On 12th day, solid tumor was developed and mice were divided into seven groups; tumor control, early CIS (ECIS), ECIS + ETQ, ECIS + ETQ + EPTX, late CIS (LCIS), LCIS + LTQ, and LCIS + LTQ + LPTX. Early treatment was started on 12th day, whereas late treatment was begun on 19th day from tumor inoculation. At the endpoint, samples were collected for detection of Notch1, Hes1, Jagged1, β-catenin, TNF-α, IL-6, IFN-γ, IL-2, VEGF, apoptosis, CD4, and CD8.Key findingsAdding PTX and TQ to CIS significantly reduced Notch1, Hes1, Jagged1, β-catenin, TNF-α, IL-6, IFN-γ, and VEGF with increment in IL-2, CD4, CD8, and apoptotic cells. Moreover, early treated groups showed remarkable attenuation in tumor growth and the relevant parameters compared to their counterpart later groups.SignificanceAddition of PTX with TQ to CIS showed a synergistic chemotherapeutic action and induced better oncostatic effect mainly through Notch suppression. Consequently, shutting Notch could be of great interest in promoting chemosensetivity and cancer contro...

CONCLUSION: The best of our knowledge it is the third description of brachial plexus schwannoma associated with breast cancer and the first with a synchronous association. The knowledge of this pathology and its potential to alter treatment justify the reporting of the present case. PMID: 32083563 [PubMed - as supplied by publisher]

This study aimed to evaluate fertility in female survivors of childhood DTC by assessing various reproductive characteristics combined with anti-Müllerian hormone (AMH) levels (a marker of ovarian reserve). Methods. Female survivors of childhood DTC, diagnosed at ≤18 years of age between 1970 and 2013 were included. Survivors were excluded when follow-up time was less than 5 years or if they developed other malignancies before or after diagnosis of DTC. Survivors filled out a questionnaire regarding reproductive characteristics (e.g. age at menarche and menopause, pregnancies, pregnancy outcomes, need for assisted ...

Authors: Zhang Y, Ying X, Zhao Q, Ma J, Zhang D, He C, Han S Abstract Background: Hepatocellular carcinoma (HCC) is a malignant tumor associated with a poor prognosis. Serum biomarkers of HCC have the potential to improve the diagnosis, provide a means to monitor the tumors, and predict their malignancy. Proteins that are expressed differentially between HCC patients and normal controls have the potential to be biomarkers. Method: Serum samples from 10 confirmed HCC patients and 10 controls were collected. The differentially expressed proteins in the serum were identified using an isobaric tags for relative and...

Authors: Jabalee J, Towle R, Lawson J, Dickman C, Garnis C Abstract Neutral sphingomyelinase 2 (nSMase2), the product of the sphingomyelin phosphodiesterase 3 (SMPD3) gene, catalyzes the hydrolysis of sphingomyelin to ceramide. Ceramide acts on various signaling pathways to influence cell proliferation, survival, and stress response. Altered levels of sphingolipids and ceramides have been reported in various cancer types, including oral squamous cell carcinoma (OSCC). OSCC patients exhibit a poor 5-year survival rate of 50%, a figure that has remained stagnant for decades. To overcome this requires a better underst...

There is heterogeneity between the behavior and response to treatment of HPV-positive oropharyngeal squamous cell carcinoma that may be linked to the tumor virome. In this prospective study, a pan-pathogen microarray (PathoChip) was used to determine the virome of early stage, p16-positive OPSCC and neck metastasis treate...

Colonoscopy with polypectomy is frequently performed in pediatric patients based on symptoms, with the majority of polyps identified being benign juvenile pedunculated polyps with a vascular stalk. This is in distinction to adults where polypectomy is often performed as part of a colon cancer screening and prevention strategy and a higher fraction of polyps are sessile and or dysplastic. In adults, polypectomy techniques emphasize a need for deeper resection to ensure complete resection of adenomas or potential carcinoma in situ. Adenomatous polyps can occur in the pediatric age group and may be associated with an underlyi...
