Glioblastoma (GBM) is a therapeutic challenge, associated with high mortality. More effective GBM therapeutic options are urgently needed. Hence, we screened a large multi-class drug panel comprising the NIH clinical collection (NCC) that includes 446 FDA-approved drugs, with the goal of identifying new GBM therapeutics for rapid entry into clinical trials(More)
The activation of signal transducers and activators of transcription 3 (STAT3) has been closely linked with the proliferation, survival, invasion, and angiogenesis of hepatocellular carcinoma (HCC) and represents an attractive target for therapy. In the present report, we investigated whether honokiol mediates its effect through interference with the STAT3(More)
PURPOSE Hepatocellular carcinoma (HCC) is the fifth most common malignancy worldwide and the third cause of global cancer mortality. Increasing evidence suggest that STAT3 is a critical mediator of oncogenic signaling in HCC and controls the expression of several genes involved in proliferation, survival, metastasis, and angiogenesis. Thus, the novel agents(More)
Activation of transcription factors nuclear factor-κB (NF-κB) and signal transducer and activator of transcription 3 (STAT3) is frequently observed in prostate cancer and has been linked with tumor cell proliferation, invasion, metastasis, and angiogenesis. In this study, we investigated the effect of ursolic acid (UA) on NF-κB and STAT3 signaling pathways(More)
BACKGROUND AND PURPOSE Activation of pro-inflammatory transcription factors NF-κB and signal transducer and activator of transcription 3 (STAT3) is one of the major contributors to both pathogenesis and chemoresistance in multiple myeloma (MM), which results in high mortality rate. Thus, in the present study, we investigated whether celastrol could suppress(More)
BACKGROUND The increasing usage of statins (the 3-hydroxy-3-methylglutaryl-coenzyme A reductase inhibitors) has revealed a number of unexpected beneficial effects, including a reduction in cancer risk. METHODS We investigated the direct anticancer effects of different statins approved for clinical use on human breast and brain cancer cells. We also(More)
Constitutive activation of STAT3 is frequently observed and closely linked with proliferation, survival, invasion, metastasis and angiogenesis in tumor cells. In the present study, we investigated whether β-caryophyllene oxide (CPO), a sesquiterpene isolated primarily from the essential oils of medicinal plants such as guava (Psidium guajava), and oregano(More)
Acute and chronic inflammation commonly occurs throughout the oral cavity. The most common causes are physical damage and microbial infections, and less frequently immune reactions and malignant changes. All of these processes result in the induction of antimicrobial peptides, chemokines and cytokines that lead to cellular infiltrates, a vascular response,(More)
Gastric cancer (GC) is a lethal malignancy and the second most common cause of cancer-related deaths. Although treatment options such as chemotherapy, radiotherapy, and surgery have led to a decline in the mortality rate due to GC, chemoresistance remains as one of the major causes for poor prognosis and high recurrence rate. In this study, we investigated(More)
BACKGROUND AND PURPOSE Aberrant activation of STAT3 is frequently encountered and promotes proliferation, survival, metastasis and angiogenesis in hepatocellular carcinoma (HCC). Here, we have investigated whether emodin mediates its effect through interference with the STAT3 activation pathway in HCC. EXPERIMENTAL APPROACH The effect of emodin on STAT3(More)
