BACKGROUND: A common class-specific toxicity of mammalian target of rapamycin (mTOR) inhibitors is stomatitis. Some patients experience a severe form of mTOR inhibitor-associated stomatitis (mIAS) that can have a negative effect on nutritional status, compromise quality of life, and potentially lead to nonadherence, reducing the efficacy of cancer therapy. OBJECTIVES: This article aims to address an unmet need for education about mIAS among oncology nurses and patients and to share findings about everolimus-related stomatitis from the SWISH trial...

Targeting the DNA damage response (DDR) in tumors with defective DNA repair is a clinically successful strategy. The RAS/RAF/MEK/ERK signalling pathway is frequently deregulated in human cancers. In this study, we explored the effects of MEK inhibition on the homologous recombination pathway and explored the potential for combination therapy of MEK inhibitors with DDR inhibitors and a hypoxia-activated prodrug. We studied effects of combining pimasertib, a selective allosteric inhibitor of MEK1/2, with olaparib, a small molecule inhibitor of poly (adenosine diphosphate [ADP]-ribose) polymerases (PARP), and with the hypoxia-activated prodrug evofosfamide in ovarian and pancreatic cancer cell lines...

Pancreatic ductal adenocarcinoma (PDAC) is one of the deadliest cancers due to a late diagnosis and poor response to available treatments. There is a need to identify complementary treatment strategies that will enhance the efficacy and reduce the toxicity of currently used therapeutic approaches. We investigated the ability of a known ROS inducer, piperlongumine (PL), to complement the modest anti-cancer effects of the approved chemotherapeutic agent gemcitabine (GEM) in PDAC cells in vitro and in vivo . PDAC cells treated with PL + GEM showed reduced cell viability, clonogenic survival, and growth on Matrigel compared to control and individually-treated cells...

Ciclopirox olamine (CPX) is an antifungal agent that has recently demonstrated promising anti-neoplastic activity against hematologic and solid tumors. Here, we evaluated CPX compared with gemcitabine alone as well as their combination in human pancreatic cancer cell lines; BxPC-3, Panc-1, and MIA PaCa-2 and in humanized xenograft mouse models. We also examined the preclinical pharmacodynamic activity of CPX. CPX caused a pronounced decrease in cell proliferation and clonogenic growth potential. These inhibitory effects were accompanied by induction of reactive oxygen species (ROS), which were strongly associated with reduced Bcl-xL and survivin levels and activation of a panel of caspases, especially caspase-3, and finally resulted in apoptotic death...

PURPOSE: About 60% of non-small cell lung cancer (NSCLC) patients develop resistance to targeted epidermal growth factor receptor (EGFR) inhibitor therapy through the EGFR T790M mutation. Patients with this mutation respond well to third generation tyrosine kinase inhibitors, but obtaining a tissue biopsy to confirm the mutation poses risks and is often not feasible. Liquid biopsies using circulating free tumor DNA (cfDNA) have emerged as a non-invasive option to detect the mutation, however sensitivity is low as many patients have too few detectable copies in circulation...

Antibody technologies are being increasingly applied in the field of toxinology. Fuelled by the many advances in immunology, synthetic biology, and antibody research, different approaches and antibody formats are being investigated for the ability to neutralize animal toxins. These different molecular formats each have their own therapeutic characteristics. In this review, we provide an overview of the advances made in the development of toxin-targeting antibodies, and discuss the benefits and drawbacks of different antibody formats in relation to their ability to neutralize toxins, pharmacokinetic features, propensity to cause adverse reactions, formulation, and expression for research and development (R&D) purposes and large-scale manufacturing...

HIV pre-exposure prophylaxis (PrEP) with emtricitabine (FTC) and tenofovir disoproxil fumarate (TDF) fixed-dose combination (FTC/TDF) is undergoing rapid scale-up in the United States. While FTC/TDF is typically well tolerated, to our knowledge, cranial nerve pathology associated with FTC/TDF has not been previously described. We report the case of a 35-year-old patient who began FTC/TDF PrEP and developed acute trigeminal neuralgia. The neurologic symptoms resolved after treatment discontinuation and recurred upon rechallenge, resulting in permanent discontinuation of PrEP treatment...

Osteoarthritis (OA) is characterized by a progressive loss of articular cartilage, subchondral bone sclerosis and synovial inflammation and is the most common chronic condition worldwide today. However, most treatments have focused on pain relief and OA symptoms. For these reasons, many ongoing studies are currently trying to develop efficient and successful therapies based on its pathology. Animal models that mimic the histopathology and symptoms of OA have a critical role in OA research and make it possible to investigate both secondary osteoarthritic changes due to a precedent event such as traumatic injury and naturally occurring changes for the development of therapeutics which can be tested in preclinical and clinical OA trials...

Cancer disparities in rural and frontier communities are an important issue in Utah because much of Utah is sparsely populated. The aims of this study were to investigate whether there are differences in the cancer incidence and 5-year survival rates in Utah by metropolitan/rural residence and to investigate disparities in distributions of cancer risk factors. We used cancer registry records to identify patients diagnosed with a first primary cancer in Utah between 2004 and 2008. We estimated 5-year survival and incidence rates...

People with visible differences are often confronted with negative observer responses, including stares, disgust, and avoidance. Characteristics of negative observer responses are well-documented, but less is known about associated factors. We conducted a scoping review to map what is known about factors associated with negative observer responses. Web of Science, PubMed, PsycINFO, and CINAHL databases were searched, and 16 articles met inclusion criteria. Two general categories of factors were identified: (1) observer characteristics, including age, sex, and socioeconomic status, experiences with disfigurements, and personal beliefs or attitudes related to visible differences; and (2) evolved internal mechanisms, including threat-detection, disgust, and disease avoidance...

The transcription factor Hes family bHLH transcription factor 1 (Hes1) is a downstream effector of Notch signaling and plays a crucial role in orchestrating developmental processes during the embryonic stage. However, its aberrant signaling in adulthood is linked to the pathogenesis of cancer. In the present study, we report the discovery of small organic molecules (JI051 and JI130) that impair the ability of Hes1 to repress transcription. Hes1 interacts with the transcriptional corepressor transducing-like enhancer of split 1 (TLE1) via an interaction domain comprising two tryptophan residues, prompting us to search a chemical library of 1,800 small molecules enriched for indole-like π-electron-rich pharmacophores for a compound that blocks Hes1-mediated transcriptional repression...

BACKGROUND: We have previously identified tissue inhibitor of metalloproteinases-1 (TIMP-1) as a prognostic marker in glioblastomas. TIMP-1 has been associated with chemotherapy resistance, and CD63, a known TIMP-1-binding protein, has been suggested to be responsible for this effect. The aim of this study was to assess CD63 expression in astrocytomas focusing on the prognostic potential of CD63 alone and in combination with TIMP-1. METHODS: CD63 expression was investigated immunohistochemically in a cohort of 111 astrocytomas and correlated to tumor grade and overall survival by semi-quantitative scoring...

Surplus electricity may be supplied to anaerobic digesters as H2 gas to upgrade the CH4 content of biogas. Acetate accumulation has been observed following H2 injections, but the parameters determining the degree of acetate accumulation are not well understood. The pathways involved during H2 consumption and acetate kinetics were evaluated in continuous lab reactors and parallel batch13 C experiments. Acetate accumulation increased during initial H2 injections as organic loading rate increased and CO2 levels decreased below 7%...
