TL;DR: Results suggest a relationship between membrane-associated p36 and the cytoskeletal fibres that terminate at the plasma membrane in PtK2 cells and show for the first time a drug-induced redistribution of p36.

TL;DR: According to these results, AdsVEGFR-2 and AdsVEgFR-3 gene therapy combined with chemotherapy is safe and can be brought to clinical testing in ovarian cancer patients.
Abstract: Antiangiogenic and antilymphangiogenic gene therapy with soluble vascular endothelial growth factor receptor-2 (VEGFR-2) and soluble VEGFR-3 in combination with chemotherapy is a potential new treatment for ovarian carcinoma. We evaluated the safety, toxicology, and biodistribution of intravenous AdsVEGFR-2 and AdsVEGFR-3 combined with chemotherapy in healthy rats (n=90) before entering a clinical setting. The study groups were: AdLacZ and AdLacZ with chemotherapy as control groups, low dose AdsVEGFR-2 and AdsVEGFR-3, high dose AdsVEGFR-2 and AdsVEGFR-3, combination of low dose AdsVEGFR-2 and AdsVEGFR-3 with chemotherapy, combination of high dose AdsVEGFR-2 and AdVEGFR-3 with chemotherapy, and chemotherapy only. The follow-up time was 4 weeks. Safety and toxicology were assessed by monitoring the clinical status of the animals and by histological, hematological, and clinical chemistry parameters. For the biodistribution studies, quantitative reverse-transcriptase polymerase chain reaction (qRT-PC...

TL;DR: About 15% of all human tumours, including carcinomas, sarcomas, melanomas and leukaemias, contain c-ras oncogenes, which can be detected by a variety of methods.
Abstract: About 15% of all human tumours, including carcinomas, sarcomas, melanomas and leukaemias, contain c-ras oncogenes, which can be detected by a variety of methods. The activating lesion in the c-ras oncogenes is most often a point mutation affecting certain critical amino acid residues of its protein product. The clinical significance of c-ras oncogenes is not yet clear.

TL;DR: In this paper, the authors present methods and compositions for making and using chimeric polypeptides that comprise a VEGFR-3 ligand and a heparin binding domain.
Abstract: The present invention is directed to methods and compositions for making and using chimeric polypeptides that comprise a VEGFR-3 ligand and a heparin binding domain. The chimeric molecules of the present invention retain VEGFR-3 binding activity and an enhanced heparin binding activity as compared to native VEGF-C and/or VEFG-D.

TL;DR: PfPMP1）与感染红细胞、树突状组胞以及胎盘的单个或多个受体作用，在黏附及免疫逃避中起关键的作�ly.
Abstract: 抗原变异可使得多种致病微生物易于逃避宿主免疫应答。表达在感染红细胞表面的恶性疟原虫红细胞表面蛋白1（PfPMP1）与感染红细胞、内皮细胞、树突状细胞以及胎盘的单个或多个受体作用，在黏附及免疫逃避中起关键的作用。每个单倍体基因组var基因家族编码约60种成员，通过启动转录不同的var基因变异体为抗原变异提供了分子基础。

TL;DR: It is now becoming clear that the tumour microenvironment, which is largely orchestrated by inflammatory cells, is an indispensable participant in the neoplastic process, fostering proliferation, survival and migration.
Abstract: Recent data have expanded the concept that inflammation is a critical component of tumour progression. Many cancers arise from sites of infection, chronic irritation and inflammation. It is now becoming clear that the tumour microenvironment, which is largely orchestrated by inflammatory cells, is an indispensable participant in the neoplastic process, fostering proliferation, survival and migration. In addition, tumour cells have co-opted some of the signalling molecules of the innate immune system, such as selectins, chemokines and their receptors for invasion, migration and metastasis. These insights are fostering new anti-inflammatory therapeutic approaches to cancer development.

TL;DR: Amplification of the HER-2/neu gene was a significant predictor of both overall survival and time to relapse in patients with breast cancer, and had greater prognostic value than most currently used prognostic factors in lymph node-positive disease.
Abstract: The HER-2/neu oncogene is a member of the erbB-like oncogene family, and is related to, but distinct from, the epidermal growth factor receptor. This gene has been shown to be amplified in human breast cancer cell lines. In the current study, alterations of the gene in 189 primary human breast cancers were investigated. HER-2/neu was found to be amplified from 2- to greater than 20-fold in 30% of the tumors. Correlation of gene amplification with several disease parameters was evaluated. Amplification of the HER-2/neu gene was a significant predictor of both overall survival and time to relapse in patients with breast cancer. It retained its significance even when adjustments were made for other known prognostic factors. Moreover, HER-2/neu amplification had greater prognostic value than most currently used prognostic factors, including hormonal-receptor status, in lymph node-positive disease. These data indicate that this gene may play a role in the biologic behavior and/or pathogenesis of human breast cancer.
