The tumor-associated antigen MUC1 is overexpressed and underglycosylated in human adenocarcinomas of diverse origins, such as breast, ovary, and colon. We isolated and describe five human single-chain (sc) Fv antibodies specific for the MUC1 variable number of tandem repeats region isolated by in vitro selection from a large naive phage antibody library containing over 6 x 10(9) different scFv ...

In the normal human colon, aldehyde dehydrogenase 1B1 (ALDH1B1) is expressed only at the crypt base, along with stem cells. It is also highly expressed in the human colonic adenocarcinomas. This pattern of expression corresponds closely to that observed for Wnt/β-catenin signaling activity. The present study examines the role of ALDH1B1 in colon tumorigenesis and signalling pathways mediating i...

Sixteen cardenolides, two hemiterpenoids, two phenylpropanoids and a phenylethanoid isolated from the roots of Streptocaulon juventas (LOUR.) MERR. were examined for their antiproliferative activity toward three human-derived (HT-1080 fibrosarcoma, lung A549 adenocarcinoma, cervix HeLa adenocarcinoma) and three murine-derived (colon 26-L5 carcinoma, Lewis lung carcinoma, B16-BL6 melanoma) cell ...

Four new BODIPY derivatives with a potential tendency to aggregation have been synthesized and characterized by means of NMR techniques, mass spectrometry UV–Vis/fluorescence spectroscopies. The objective this study is determine which structural factors the molecules influence most notably cellular uptake, intracellular location fluorescence imaging abilities. behaviour compounds in organic sol...

The metabolism is reprogrammed in cancer cells to meet the requirement of their malignant properties. Some specific metabolites can contribute transformation different types. This study aimed determine level glucose, pyruvate, lactate, citrate, alpha-ketoglutarate (α-KG), 2-hydroxyglutarate (2-HG), succinate, fumarate, malate, and oxaloacetate tissues (tumor, colon, brain, liver) xenograft mode...

soybean isoflavone genistein has multiple anticancer properties and its pro-apoptotic and anti-proliferative effects have been studied in different cancer cells. however, the mechanisms of action of genistein and its molecular targets on human colon cells have not been fully elucidated. therefore, caspase-3 and p38 mitogen-activated protein kinase (p38 mapk) as the main therapeutic targets were...

A series of twenty two novel 1-cyclopropyl-6-fluoro-4-oxo-7-(4-substituted piperazin-1-yl)-1,4-dihydroquinoline-3-carboxylic acid analogues have been synthesized, characterized ((1)H NMR, (13)C NMR and LCMS) and evaluated for their inhibitory activity on the proliferation of human caucasian acute lymphoblastic leukemia cells (CCRF-CEM), breast adenocarcinoma cells (MDA-MB-468) and human colon c...

Altered chromatin structure is a hallmark of cancer, and inappropriate regulation of chromatin structure may represent the origin of transformation. Important studies have mapped human nucleosome distributions genome wide, but the role of chromatin structure in cancer progression has not been addressed. We developed a MNase-Transcription Start Site Sequence Capture method (mTSS-seq) to map the ...

This study aimed to determine the phytochemical profiles,in vitroantioxidant and antiproliferative properties of KoreanCamellia mistletoe(Korthalsella japon-ica(Thunb.) Engl.) depending on harvest time (August November) sol-vent (100% methanol, 70% ethanol, hot water). TheCamellia japonicaL. mistle-toe extracts were analyzed for total phenol, flavonoid, carotenoid, L-ascorbic acid contents anti...

Introduction and objective. Barley (Hordeum vulgare L.) is known as a rich source of different bioactive compounds. At present, considerable attention of researchers is focused on young barley grass. It can be a good source of dietary minerals, vitamins, carbohydrates, amino acids, phenolic compounds and proteins. It is possible that the composition of chemical ingredients beneficial for...
