In the recent years deregulation for microRNAs expression pattern have emerged as a possible molecular factor for carcinogenesis. It has been reported that the expression of miR-9 was down-regulated in human gastric adenocarcinoma. To figure out the molecular mechanism of this down regulation, the methylation status in promoters of miR-9 family loci were compared in the human gastric adenocarci...

A 60-year-old female with an unknown family history initially presented with signs and symptoms concerning for gastrointestinal cancer. Regular breast cancer screening and subsequent work-up around this time demonstrated the presence of T2N1 stage II triple positive ductal adenocarcinoma of the left breast. Follow-up imaging for her gastrointestinal symptoms demonstrated a 3.5 cm solitary mass ...

A novel class of 6-indolypyridine-3-carbonitrilile derivatives were synthesized and evaluated for antiproliferative activities to establish structure-activity relationship. The synthesis was carried out through one-pot multicomponent reaction of 3-acetylindole, aromatic aldehydes, ethyl cyanoacetate, and ammonium acetate in the presence of piperidine as a catalyst, using a microwave irradiation...

The incidence of cervical adenocarcinoma, which accounts for 10-20% of all cervical cancers, has increased continuously in developed countries during the last two decades, unlike squamous cell cervical carcinoma. This increasing trend, noted particularly among women under the age of 40 years, has occurred despite extensive cytological Pap smear sc...

The safety of silicone-based implant for mammoplasty has been debated for decades. A series of anecdotal case reports and a recent epidemiological case-control study have suggested a possible association between silicone implant and the development of primary breast ALK1-negative anaplastic large cell lymphoma (ALCL), a rare type of peripheral T-cell lymphoma. In this report, we describe an add...

The higher frequency of lung adenocarcinoma in women smokers than in men smokers suggests a role for gender-dependent factors in the etiology of lung cancer. We evaluated estrogen receptor (ER) alpha and beta expression and activity in human lung adenocarcinoma cell lines and normal lung fibroblasts. Full-length ERalpha and ERbeta proteins were expressed in all cell lines with higher ERbeta tha...

The synthesis and biomedical applications of nano/micromotors have attracted great attention. In this work, preparation characterization catalytic gold/poly(3,4-ethylenedioxythiophene)/platinum (Au/PEDOT/Pt) micromotors were reported to present their contribution for cancer biomarker miRNA-21 detection. Potential use these motors possible treatment was also illustrated after biocompability had ...

Background: Poekilocerus pictus (Fabricius 1771), a painted grasshopper, sequesters cardenolides from its food plant, the Apple of Sodom or Aak, Calotropis procera (Aiton) W.T. Aiton (Family-Asclepiadaceae). In our present investigation, we were able to isolate Pseudomonas aeruginosa KRK6 intestine responsible for biotransformation cardenolides. Methods: was grown in methanolic extracts and mod...

Integrin ανβ6 has emerged as a potential novel target for anticancer and plays a major role in promoting malignant tumor progression. Recent studies indicate that integrin ανβ6 occurs in many cancers. However, whether and how ανβ6 is regulated by genetic and epigenetic mechanisms in breast cancer remain unknown. In the present study, two different short hairpin RNAs (shRNAs) targeting the β6 ge...

A unique mouse hybridoma, PR92, was obtained using human prostate adenocarcinoma cell line DU145. The monoclonal antibody produced by the PR92 clone was reactive with DU145, MCF-7 (breast adenocarcinoma), and CHAGO (lung carcinoma), but not with normal cell lines and 16 other cell lines of cancerous origin. A homologous solid-phase sandwich radioimmunoassay (PR92-RIA) was developed utilizing PR...
