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 to patient's poor prognosis of lung cancer. It has been reported that hypoxia and autophagy are contributing to this resistance partly. However, there is controversy over whether autophagy plays 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 12h hypoxia or normoxia before irradiation...

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 mellitus. 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...

Nuclear factor of activated T cells 5 (NFAT5) has been implicated in the pathogenesis of various human diseases, including cancer and arthritis. However, therapeutic agents inhibiting NFAT5 activity are currently unavailable. To discover NFAT5 inhibitors, a library of >40,000 chemicals was screened for the suppression of nitric oxide, a direct target regulated by NFAT5 activity, through high-throughput screening. We validated the anti-NFAT5 activity of 198 primary hit compounds using an NFAT5-dependent reporter assay and identified the novel NFAT5 suppressor KRN2, 13-(2-fluoro)-benzylberberine, and its derivative KRN5...

STUDY QUESTION: What is the underlying mechanism of Sertoli cell (SC) resistance to cell death? SUMMARY ANSWER: High expression of pro-survival B cell lymphoma-2 (BCL2) proteins and inhibition of apoptosis and autophagy prolongs SC survival upon exposure to stress stimuli. WHAT IS KNOWN ALREADY: In human and in experimental models of orchitis, tolerogenic SC survive stress conditions, while germ cells undergo massive apoptosis. In general, non-dividing highly differentiated cells tend to resist stress conditions for a longer time by favoring activation of pro-survival mechanisms and inhibition of cell death pathways...

Methionine (Met) is involved in one-carbon de novo nucleotide synthesis and is an essential amino acid for cell survival. The impact of lactate calcium salt (CaLa) on the Met metabolism was investigated to evaluate the enhanced antitumor effect of methotrexate (MTX) on colorectal cancer (CRC) cells. Met dependency relating to homocysteine (Hcy) and betaine was investigated in human CRC cells (HCT-116 and HT-29) using a viability assay and liquid chromatography-mass spectrometry. Expression of betaine transporter-1 (BGT-1) following treatment with MTX alone or with CaLa was determined by Western blot...

The treatment of various N-morpholino amides with TMPZnCl⋅LiCl (TMP=2,2,6,6-tetramethylpiperidyl) and Mg(OPiv)2 in THF at 25 °C provides solid zinc enolates with enhanced air and moisture stability (t1/2 in air: 1-3 h) after solvent evaporation. These enolates undergo Pd- and Cu-catalyzed cross-couplings with (hetero)aryl bromides as well as allylic and benzylic halides. The arylated N-morpholino amides were converted into various ketones by LaCl3 ⋅2 LiCl mediated acylation with Grignard reagents...

Hyponatremia is a common electrolyte disorder in cancer patients and has been associated with poor prognosis. A frequent cause of cancer-related hyponatremia is the syndrome of inappropriate antidiuretic hormone (SIADH). This study was a post hoc subgroup analysis of the SALT-1 (Study of Ascending Levels of Tolvaptan in Hyponatremia) and SALT-2 clinical trials. Hyponatremic subjects with SIADH and cancer received the oral selective vasopressin V2-receptor antagonist tolvaptan (n = 12) or matching placebo (n = 16) once-daily for 30 days...
