Cystathionine gamma-lyase/H2 S signaling facilitates myogenesis under aging and injury condition.

Yanjie Zhang, Laura Masters, Yuehong Wang, Lingyun Wu, Yanxi Pei, Baoqing Guo, Amadeo Parissenti, Simon J Lees, Rui Wang, Guangdong Yang,

Hydrogen sulfide (H<sub>2</sub> S) can be endogenously produced and belongs to the class of signaling molecules known as gasotransmitters. Cystathionine gamma-lyase (CSE)-derived H<sub>2</sub> S is implicated in the regulation of cell differentiation and the aging process, but the involvements of the CSE/H<sub>2</sub> S system in myogenesis upon aging and injury ...

The RNA disruption assay is superior to conventional drug sensitivity assays in detecting cytotoxic drugs.

Jonathan P J Mapletoft, Renée J St-Onge, Baoqing Guo, Phillipe Butler, Twinkle J Masilamani, Lavina D'costa, Laura B Pritzker, Amadeo M Parissenti,

Conventional drug sensitivity assays used to screen prospective anti-cancer agents for cytotoxicity monitor biological processes associated with active growth and proliferation, used as proxies of cell viability. However, these assays are unable to distinguish between growth-arrested (but otherwise viable) cells and non-viable/dead cells. As a result, compounds selected based on ... Read more >>

Chemotherapy and Inflammatory Cytokine Signalling in Cancer Cells and the Tumour Microenvironment.

Derek W Edwardson, Amadeo M Parissenti, A Thomas Kovala,

Cancer is the result of a cell's acquisition of a variety of biological capabilities or 'hallmarks' as outlined by Hanahan and Weinberg. These include sustained proliferative signalling, the ability to evade growth suppressors, resisting cell death, enabling replicative immortality, inducing angiogenesis, and the ability to invade other tissue and metastasize. ...

Bile Acids Increase Doxorubicin Sensitivity in ABCC1-expressing Tumour Cells.

Simon Chewchuk, Tyler Boorman, Derek Edwardson, Amadeo M Parissenti,

Tumour cells possess or acquire various mechanisms to circumvent the cytotoxic effects of chemotherapy drugs. One such mechanism involves the overexpression of ABC transporters that facilitate the extrusion of a variety of structurally distinct chemotherapy drugs from the cytoplasm into the extracellular space. While specific ABC transporter inhibitors have been ... Read more >>

Inflammatory cytokine production in tumor cells upon chemotherapy drug exposure or upon selection for drug resistance.

Derek W Edwardson, Justin Boudreau, Jonathan Mapletoft, Carita Lanner, A Thomas Kovala, Amadeo M Parissenti,

Tumor Necrosis Factor alpha (TNF-α) has been shown to be released by tumor cells in response to docetaxel, and lipopolysaccharides (LPS), the latter through activation of toll-like receptor 4 (TLR4). However, it is unclear whether the former involves TLR4 receptor activation through direct binding of the drug to TLR4 at ... Read more >>

Sensitivity of docetaxel-resistant MCF-7 breast cancer cells to microtubule-destabilizing agents including vinca alkaloids and colchicine-site binding agents.

Richard C Wang, Xinmei Chen, Amadeo M Parissenti, Anil A Joy, Jack Tuszynski, David N Brindley, Zhixiang Wang,

<h4>Introduction</h4>One of the main reasons for disease recurrence in the curative breast cancer treatment setting is the development of drug resistance. Microtubule targeted agents (MTAs) are among the most commonly used drugs for the treatment of breaset cancer and therefore overcoming taxane resistance is of primary clinical importance. Our group ... Read more >>

Alterations in estrogen signalling pathways upon acquisition of anthracycline resistance in breast tumor cells.

Simon Chewchuk, Baoqing Guo, Amadeo Mark Parissenti,

Intrinsic or acquired drug resistance is a major impediment to the successful treatment of women with breast cancer using chemotherapy. We have observed that MCF-7 breast tumor cells selected for resistance to doxorubicin or epirubicin (MCF-7DOX2 and MCF-7EPI cells, respectively) exhibited increased expression of several members of the aldo-keto reductase ...

Targeting multidrug-resistant ovarian cancer through estrogen receptor α dependent ATP depletion caused by hyperactivation of the unfolded protein response.

Xiaobin Zheng, Neal Andruska, Michael J Lambrecht, Sisi He, Amadeo Parissenti, Paul J Hergenrother, Erik R Nelson, David J Shapiro,

Ovarian cancers often recur and tumors acquire resistance to chemotherapy due to overexpression of the ATP-dependent efflux pump, multidrug resistance protein 1 (MDR1/P-glycoprotein/ABCB1). Nontoxic small molecule inhibitors targeting MDR1 have remained largely elusive. Instead, in a novel application of our recently described estrogen receptor α (ERα) biomodulator, BHPI, we targeted ... Read more >>

Derek W Edwardson, Rashmi Narendrula, Simon Chewchuk, Kyle Mispel-Beyer, Jonathan P J Mapletoft, Amadeo M Parissenti,

Many clinical studies involving anti-tumor agents neglect to consider how these agents are metabolized within the host and whether the creation of specific metabolites alters drug therapeutic properties or toxic side effects. However, this is not the case for the anthracycline class of chemotherapy drugs. This review describes the various ... Read more >>

Jason A Sprowl, Kerry Reed, Stephen R Armstrong, Carita Lanner, Baoqing Guo, Irina Kalatskaya, Lincoln Stein, Stacey L Hembruff, Adam Tam, Amadeo M Parissenti,

INTRODUCTION: The taxanes paclitaxel and docetaxel are widely used in the treatment of breast, ovarian, and other cancers. Although their cytotoxicity has been attributed to cell-cycle arrest through stabilization of microtubules, the mechanisms by which tumor cells die remains unclear. Paclitaxel has been shown to induce soluble tumor necrosis factor ... Read more >>

The effect of ABCB1 genetic variants on chemotherapy response in HIV and cancer treatment.

Kerry Reed, Amadeo M Parissenti,

Despite their clearly distinct pathophysiologies, HIV and cancer are diseases whose response to chemotherapy treatment varies substantially amongst patients, in particular for those with prior drug exposure. This has been attributed, in part, to elevated expression of the ABCB1 drug transporter in some patients, which results in reduced drug accumulation ... Read more >>

Comparison of bisulfite sequencing PCR with pyrosequencing for measuring differences in DNA methylation.

Kerry Reed, Matthew L Poulin, Liying Yan, Amadeo M Parissenti,

DNA methylation strongly affects chromatin structure and the regulation of gene expression. For many years, bisulfite sequencing PCR (BSP) has served as the "gold standard" for measuring DNA methylation. However, with the evolution of pyrosequencing as a tool to evaluate DNA methylation, the need arises to compare the relative efficiencies ... Read more >>

Induction of 1C aldoketoreductases and other drug dose-dependent genes upon acquisition of anthracycline resistance.

Zachary W Veitch, Baoqing Guo, Stacey L Hembruff, Adam J Bewick, Allan D Heibein, Jamei Eng, Stephanie Cull, David A Maclean, Amadeo M Parissenti,

<h4>Objectives</h4>Recent studies suggest that tumor cells overexpressing aldoketoreductases (AKRs) exhibit increased resistance to DNA damaging agents such as anthracyclines. AKRs may induce resistance to the anthracycline doxorubicin by catalyzing its conversion to the less toxic 13-hydroxy metabolite doxorubicinol. However, it has not been established whether during selection for anthracycline resistance, ... Read more >>
