Triple-negative breast cancer (TNBC) and colon cancer (CC) are two stigmatic examples of poorly treatable tumors, whose progression critically depends upon hyperactivation of the Wnt signaling. Development of specific anti-Wnt inhibitors is required to develop drugs against these and other Wnt-dependent cancers. Natural products, especially plants, have been used for the treatment of various diseases from ancient times. We examined extracts from several indigenous Cameroonian herbs and tested their effects on proliferation and Wnt signaling in TNBC and CC cells...

PURPOSE: Chemotherapeutic resistance eventually develops in all patients with metastatic colorectal cancer (mCRC). Gene silencing through promoter demethylation is one potential reversible mechanism of resistance with administration of hypomethylating agents. We evaluated the safety and tolerability of guadecitabine and irinotecan in mCRC patients previously treated with irinotecan. EXPERIMENTAL DESIGN: In this 3+3 dose-escalation study, mCRC patients previously exposed to irinotecan received guadecitabine days 1-5 of a 28 day cycle and irinotecan 125mg/m2 days 8 and 15 [dose level (DL) 1, guadecitabine 45mg/m2; DL -1: guadecitabine 30mg/m2; DL -1G: guadecitabine 30mg/m2 with growth factor support (GFS); DL 1G: guadecitabine 45mg/m2 with GFS...

The identification of reliable predictive biomarkers of efficacy or resistance to immune-oncology (I-O) agents is a major issue for translational research and clinical practice. However, along with PDL1 and molecular features other clinical, radiological and laboratory factors can be considered for the selection of those patients who would not be the best candidate for immune-checkpoint inhibitors (ICPIs). We examined these factors, emerging from the results of currently available studies in non-small cell lung cancer (NSCLC), aiming to provide a useful and manageable tool which can help Oncologists in their everyday clinical practice...

BACKGROUND: Curcumin, a well-studied component in turmeric, exhibits potent antitumor effects in colorectal cancer. Previous studies showed that turmerones raised the accumulation of curcumin inside colonic cells, and curcumin present in turmeric ethanolic extract had enhanced anti-tumor activities in mice. Metastasis accounts for more than 90% colorectal cancer deaths. However, the anti-metastatic effect of turmeric extract on colorectal cancer is still unknown. METHODS: In the present study, colony formation, scratch, transwell and Western blot were used to assess colony formation, motility, migration and underlying mechanisms in vitro, respectively...

BACKGROUND: The Musashi (MSI) family of RNA-binding proteins is best known for the role in post-transcriptional regulation of target mRNAs. Elevated MSI1 levels in a variety of human cancer are associated with up-regulation of Notch/Wnt signaling. MSI1 binds to and negatively regulates translation of Numb and APC (adenomatous polyposis coli), negative regulators of Notch and Wnt signaling respectively. METHODS: Previously, we have shown that the natural product (-)-gossypol as the first known small molecule inhibitor of MSI1 that down-regulates Notch/Wnt signaling and inhibits tumor xenograft growth in vivo...

Substantial efforts are underway for prevention of early stages or recurrence of colorectal cancers (CRC) or new polyp formation by chemoprevention strategies. Several epidemiological, clinical and preclinical studies to date have supported the chemopreventive potentials of several targeted drug classes including non-steroidal anti-inflammatory drugs (NSAIDs) (aspirin, naproxen, sulindac, celecoxib, and licofelone), statins and other natural agents-both individually, and in combinations. Most preclinical trials although were efficacious, only few agents entered clinical trials and have been proven to be potential chemopreventive agents for colon cancer...
