This work describes the molecular properties of the polypeptide core of a human pancreatic mucin antigen isolated from a human pancreatic adenocarcinoma cell line, HPAF. Pancreatic tumor mucin was isolated by a combination of molecular sieve Chromatograph) and CsCI/4 M guanidine-HCI density gradient ultracentrifugation. Trifluoromethane sulfonic acid was used to remove carbohydrate units from p...

objective: the objective of this study is to develop and assess targeted pamam-peg nanocarrier with anti-tag72 nanobody for t-bid gene coding construct delivery into the human colonic adenocarcinoma cells. materials and methods: nanobody (nb) coding sequence was subcloned into psj expression vector for large-scale production and then nb was purified by ni++ affinity chromatography. sds-page an...

BACKGROUND Cutaneous metastasis of gastric adenocarcinoma is rare and usually presents in men, as nodules over the abdomen. We present the case of a woman with cutaneous metastasis of gastric adenocarcinoma showing unusual clinicopathological features. CASE REPORT A 37-year-old woman developed florid cutaneous metastasis over the skin of the left breast two years after total gastrectomy for a...

Obesity is an epidemic in the US and an established risk factor for breast cancer incidence and morbidity. In obese patients breast cancer is commonly more aggressive and associated with poor prognosis. The goal of our research is to develop safe and efficient novel therapies to treat aggressive breast tumors, like those in obese patients. To enhance drug uptake we intend to develop electro-end...

Twelve novel acenaphthene derivatives have been synthesized. The structures of all compounds were confirmed by ¹H-NMR, MS and elemental analysis. Their antitumor activities were evaluated in six human solid tumor cell lines, namely non-small cell lung cancer (H460), human colon adenocarcinoma (SW480), human breast cancer cell (MDA-MB-468 and SKRB-3), human melanoma cell (A375) and human pancrea...

The present work reports an efficient synthesis of fluorinated pyridinium salts-based hydrazones under both conventional and eco-friendly ultrasound procedures. The synthetic approach first involves the preparation of halogenated pyridinium salts through the condensation of isonicotinic acid hydrazide (1) with p-fluorobenzaldehyde (2) followed by the nucleophilic alkylation of the resulting N-(...

The centrosome plays an important role in maintenance of cell polarity and in progression through the cell cycle by determining the number, polarity, and organization of interphase and mitotic microtubules. By examining a set of 35 high grade human breast tumors, we show that centrosomes of adenocarcinoma cells generally display abnormal structure, aberrant protein phosphorylation, and increase...

Mutations in the TP53 gene are very common in human cancers, and are associated with poor clinical outcome. Transgenic mouse models lacking the Trp53 gene or that express mutant Trp53 transgenes produce tumours with malignant features in many organs. We previously showed the transcriptome of a p53-deficient mouse skin carcinoma model to be similar to those of human cancers with TP53 mutations a...

PURPOSE Invasive breast carcinoma is the most common cancer in women as in non-ovariectomised pet dogs, which are already identified as a valuable spontaneous preclinical model for that disease. Geographical and time trends suggest that environmental factors may play an important role in the etiology and pathogenesis of breast cancer. Persistent organic pollutants (POPs) fit perfectly with thes...
