Christine Hosp, Henning Hamm
Hyperhidrosis affects 4.8% of the U.S. population and has been underestimated by physicians for long time despite considerable interference with quality of life. Many patients suffer from primary (idiopathic) hyperhidrosis which results from over-activity of sympathetic nerves and is restricted to specific body areas, mostly the axillae, palms, soles, or head. Secondary hyperhidrosis is caused by an underlying disease or the intake of medications and often involves large parts of the body. Numerous effective therapies with topical or systemic drugs and surgical options are available...

Chronic inflammation is a well-known precursor for cancer development and proliferation. We have recently demonstrated that high salt (NaCl) synergizes with sub-effective interleukin (IL)-17 to induce breast cancer cell proliferation. However, the exact molecular mechanisms mediating this effect are unclear. In our current study, we adopted a phosphoproteomic-based approach to identify salt modulated kinase-proteome specific molecular targets. The phosphoprotemics based binary comparison between heavy labelled MCF-7 cells treated with high salt (Δ0...

The main aim of this study is to assess the safety and antitumor efficacy of a palladium(II) (Pd)-saccharinate complex with terpyridine. To characterize the Pd(II) complex in vitro, its cytotoxicity was evaluated using a water-soluble tetrazolium salt cell viability assay and the mechanism of cell death was assessed by DNA fragmentation/condensation and live cell imaging analyses. The antitumor efficacy and safety of the Pd(II) complex in-vivo were examined by analyzing reduction in tumor size, changes in body and organ weight, histopathological analysis of liver, kidney, and tumor sections, and biochemical analysis of serum in C57BL/6 mice...

Many studies are based on the hypothesis that recurrence and drug resistance in lung carcinoma are due to a subpopulation of cancer stem-like cells (CSLCs) in solid tumors. Therefore it is crucial to screen for and recognize lung CSLCs. In this study, we stimulated non-small cell lung cancer (NSCLC) A549 cells to display stem cell-like characteristics using a combination of five small molecule compounds. The putative A549 stem cells activated an important CSLC marker, CD133 protein, as well multiple CSLC-related genes including ATP-binding cassette transporter G2 (ABCG2), C-X-C chemokine receptor type 4 (CXCR4), NESTIN, and BMI1...

PURPOSE OF REVIEW: The current review will focus on drug hypersensitivity reactions to chemotherapy specifically to those drugs most used in children. We know that potentially all chemotherapeutic agents can cause infusion reactions, generally defined as adverse drug reactions. Of these, some are Type A, defined as expected and described in the characteristics of the drug and others, and Type B, defined as unexpected reactions which cannot be explained by the known toxicity profile of the drug...

Although PARP inhibitors target BRCA1 or BRCA2 mutant tumour cells, drug resistance is a problem. PARP inhibitor resistance is sometimes associated with the presence of secondary or "revertant" mutations in BRCA1 or BRCA2 Whether secondary mutant tumour cells are selected for in a Darwinian fashion by treatment is unclear. Furthermore, how PARP inhibitor resistance might be therapeutically targeted is also poorly understood. Using CRISPR-mutagenesis, we generated isogenic tumour cell models with secondary BRCA1 or BRCA2 mutations...

In Peru, the incidence of gastric cancer is reported to be around 15.8 per 100,000 inhabitants and it is the second most common oncological disease in men and the third one in women. Additionally, a high mortality index was reported, especially among poor people. To address this issue, in 2008, Peru initiated several insurance treatment plans of oncological diseases with promising results. In Mexico, there is a high predominance of gastric cancer in male gender compared to female gender, even reaching a 2/1 ratio, and the detection rate of early gastric cancer is low (10% to 20%) which results in a mainly palliative treatment with an overall survival rate in 5 years about 10% to 15% only...

CCAAT/enhancer-binding protein (C/EBP) α, C/EBPβ and C/EBPδ are involved in inflammation and cell differentiation. In the present study, their roles in human gastric cancer cells were investigated. The human gastric cancer cell lines MKN45 and MKN74 were subjected to the reverse transcription-quantitative polymerase chain reaction (RT-qPCR) to analyze the expression levels of C/EBPα, C/EBPβ and C/EBPδ. The cells were transfected with expression plasmids for either C/EBPα or C/EBPδ, and subjected to a 3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium inner salt (MTS) assay and RT-qPCR for analysis of cyclin D1 expression...

BACKGROUND/AIM: 5-Fluorouracil (5-FU) over-use has led to an urgent need for alternative treatment regimens, such as a lower concentration of the drug because of its toxic effects. The aim of this study was to investigate the possibility of improving the antitumor effect of 5-FU without toxicity by targeting primary colorectal cancer (CRC) with sustained calcium supplementation. MATERIALS AND METHODS: The viability of CRC cells was determined after treatment of 5-FU, lactate calcium salt (CaLac), or the combination of te two...

Although siRNA-based nanomedicines hold promise for cancer treatment, conventional siRNA-polymer complex (polyplex) nanocarrier systems have poor pharmacokinetics following intravenous delivery, hindering tumor accumulation. Here, we determined the impact of surface chemistry on the in vivo pharmacokinetics and tumor delivery of siRNA polyplexes. A library of diblock polymers was synthesized, all containing the same pH-responsive, endosomolytic polyplex core-forming block but different corona blocks: 5 kDa (benchmark) and 20 kDa linear polyethylene glycol (PEG), 10 kDa and 20 kDa brush-like poly(oligo ethylene glycol), and 10 kDa and 20 kDa zwitterionic phosphorylcholine-based polymers (PMPC)...

Treatment of triple negative breast cancer (TNBC) has been a big challenge since it is defined. To date, platinum-based chemotherapy has played a significant role in the treatment of TNBC patients. However, some patients do not respond to platinum salts or gradually develop chemoresistance, resulting in little effect, or even some adverse effects. Here, we review numerous preclinical and clinical investigations to summarize possible mechanisms and potential predictive biomarkers of platinum in TNBC. The homologous recombination deficiency (HRD) resulting from the loss of BRCA function is the main rationale of platinum efficacy in TNBC...

Gastric cancer represents a diffuse and aggressive neoplasm, whose mortality index is among the highest in the world. Predisposing factors are E-cadherin mutations, Helicobacter pylori infection and a diet rich in salted and smoked food, with a low intake of fresh fruits and vegetables. Here we analyzed the effect of total lipophilic extracts of two Southern Italy tomato varieties, San Marzano and Corbarino, on an in vitro model of gastric cancer, YCC-1, YCC-2 and YCC-3 cell lines, characterized by different aggressiveness...

Cachexia is defined as a complex metabolic syndrome associated with underlying illness that is characterized by the loss of body weight consisting of muscle and fat mass wasting. Sarcopenia is defined as the ageing related loss of muscle mass in health and disease that may not have an effect on body weight. As millions of patients are in cachectic or sarcopenic states, both conditions contribute to high numbers to death worldwide. A number of treatments have been proposed for cachexia and sarcopenia, but these are either in the preclinical stage or in clinical trials and hence not available to the general population...

PURPOSE: Tumor resistance towards radiation has been a big obstacle in the poor prognosis of lung cancer. It has been reported that hypoxia and autophagy partly contribute to this resistance. However, there is controversy over whether autophagy plays a positive role in cancer therapy or not. We aim to find out the specific mechanism of radiation resistance. MATERIALS AND METHODS: A549 cells were treated with conditioned medium (CM) under 12 h hypoxia or normoxia before irradiation, followed by the measurement of clonogenic survival, reactive oxygen species (ROS), signal of mitochondria and autophagy flux...

Chemotherapeutics specifically targeting cancer cells without damaging healthy cells is the long-awaited goal of cancer treatment. In this paper, a series of nanoparticles (NanoTPES 1-4) assembled from pyridinium-substituted tetraphenylethylene salts were synthesized and investigated both in vitro and in vivo for this purpose. By changing the counter anions, NanoTPES 1-4 exhibit tunable emission colors, sizes and surface charges. NanoTPES 2 and 3 with tetraphenyl borate and tetra(4-chlorophenyl) borate as the respective anions selectively imaged and targeted mitochondria in cancer cells...

BACKGROUND: Ovarian cancer is the leading cause of death for gynecological cancers and the 6th cause of women cancer death in developed countries. The late stage detection, the peritoneal dissemination and the acquisition of resistance against carboplatin are the main reasons to explain this poor prognosis and strengthen the need of alternative treatments to improve the management of ovarian cancer and/or to sensitize tumors to platinum salts. Epidermal growth factor receptor (EGFR), hepatocyte growth factor receptor (Met) and cellular Src kinase (c-Src) are crucial kinases implied in ovarian tumor growth, survival, invasion and resistance to carboplatin...

Glyburide is widely used for the treatment of type 2 diabetes. We studied the mechanisms involved in the disposition of glyburide and its pharmacologically active hydroxy metabolites M1 and M2b and evaluated their clinical pharmacokinetics and the potential role in glyburide-induced cholestasis employing physiologically based pharmacokinetic (PBPK) modeling. Transport studies of parent and metabolites in human hepatocytes and transfected cell systems imply hepatic uptake mediated by organic anion-transporting polypeptides...

Human CAXII was initially identified as a cancer marker in different cancers and tumors. Expression of CAXII is regulated by hypoxia and estrogen receptors. CAXII expression has been also detected in several tissues, whereas in cancer and tumor tissues its expression is several fold higher. In brain tumors, an alternatively spliced form of CAXII is expressed. Higher expression of CAXII in breast cancer is indicative of lower grade disease. CAXII plays a key role in several physiological functions. Mutation in the CAXII gene causes cystic fibrosis-like syndrome and salt wasting disease...

Broccoli (Brassica oleracea L. var. italica) sprouts contain glucosinolates (GLs) that when hydrolysed yield health promoting isothiocyanates such as sulforaphane (SF). SF content can be increased by salt (NaCl) stress, although high salt concentrations negatively impact plant growth. Salicylic acid (SA) treatments can attenuate the negative effects of salt on growth. To test whether sprout isothiocyanate content could be elevated without sprout growth being compromised, broccoli seed were germinated and grown for seven days in salt (0, 80 and 160 mM) alone and in combination with 100 μM SA...

Epithelial ovarian cancer (EOC) affects 4500 women a year in France, with a survival of 30% at 5 years. Treatment is based on extensive surgery and chemotherapy. Around 15% of EOCs are due to genetic mutation predisposition essentially with mutated BRCA1 and BRCA2 genes. Four histological subtypes are described (serous, endometrioid, and mucinous cells to clear), corresponding to different carcinogenesis and distinct molecular mutations. High-grade serous EOCs have a mutation of the BRCA genes in 20-30% of cases...
