Far too often, cancer patients and their doctors aren ’t aware of all the side effects that accompany new cancer therapies. Some of these new medications might cause fatigue, muscle aches, general pain and discomfort. A lack of information can lead to patients being unprepared to manage their symptoms or even cause some to delay or stop treatment all together. Historically, many clinical trials did not have a method to analyze or widely report the patient’s experience while undergoing a therapy.  Researchers at UCLA and across the country are trying to change that. To help people in making better-informed ...

PowellTumors resistant to PARP inhibitors frequently show signs of replication stress, with hyper-activated PARP. In this issue of Cancer Cell, Pillay et al. demonstrate that inhibiting PAR-chain turnover results in cell-cycle arrest, which is cytotoxic when combined with cell-cycle checkpoint inhibition and constitutes a novel cancer therapy.

Authors: Wu H, Jiang W, Li B, Yang H, Zhao X, Zhang H, Wang S, Peng L, Wang L, Wang X, Dai G, Fang C Abstract The expression of leucine aminopeptidase 3 (LAP3) is associated with the prognosis for and malignant transformation of many types of tumors. Therefore, a LAP3 inhibitor may represent a new strategy for cancer therapy. Evaluating the suppression of enzyme activity by an LAP3 inhibitor is essential. Right now, leucine aminopeptidases (LAPs) purified from the porcine kidneys are the only enzymes that can be used to evaluate the suppression of enzyme activity by an LAP3 inhibitor. This approach cannot accuratel...

fellner Antibody-drug conjugates (ADCs) combine the tumor selectivity of antibodies with the potency of cytotoxic small molecules thereby constituting antibody-mediated chemotherapy. As this inherently limits the adverse effects of the chemotherapeutic, such approaches are heavily pursued by pharma and biotech companies and have resulted in four FDA (Food and Drug Administration)-approved ADCs. However, as with other cancer therapies, durable responses are limited by the fact that under cell stress exerted by these drugs, tumors can acquire mechanisms of escape. Resistance can develop against the antibody component of ...

In this study, a series of chalcone derivatives was screened by in vitro cytotoxicity against the wild type (A431 and A549) and mutant EGFR (H1975 and H1650) cancer cell lines, and, subsequently, tested for EGFR-tyrosine kinase (TK) inhibition. From the experimental screening, all chalcones seemed to be more active against the A431 than the A549 cell line, with chalcones 1c, 2a, 3e, 4e, and 4t showing a more than 50% inhibitory activity against the EGFR-TK activity and a high cytotoxicity with IC50 values of < 10 µM against A431 cells. Moreover, these five chalcones showed more potent on H1975 (T790M/L858R...

acute;gyi T Abstract Tyrosine kinases play crucial roles in cellular development and tumorigenesis. Tyrosine kinase inhibitors (TKIs) are effective and widely used drug molecules in targeted cancer therapies. Altered expressions of protooncogenes and tumor suppressor genes after DMBA (7,12-dimethylbenz[a]anthracene) treatment have been described as early markers of tumor induction; however their tissue-specific effects remain still unclear. Our study was aimed at examining the short-term possible antineoplastic and chemopreventive effects of a TKI compound (imatinib mesylate) on a DMBA-induced mouse tumor model. I...
