Mucins are highly immunogenic glycoproteins that are abundantly expressed by breast carcinomas and other carcinomas. The fact that deglycosylated normal mucin can induce tumor-specific monoclonal antibodies indicates that tumor-specific epitopes are hidden in the fully glycosylated form. Using
Antiangiogenesis is an appealing therapeutic modality for the treatment of a number of clinically important diseases, including human malignancies and specifically breast cancer. For years, such an approach has remained little more than good theory. However, recent studies have suggested that
OBJECTIVE
Multidrug resistance (MDR) continues to be a major obstacle for successful anticancer therapy. One of the principal factors implicated in MDR is the over expression of P-glycoprotein (Pgp), the product of the MDR1 gene.
METHODS
Here we explore the possibility of using the transcription
Although many case-control studies have suggested positive associations between carbohydrate intake and breast cancer incidence rates in both pre- and postmenopausal women, there is limited information available from cohort studies. We examined the effect of the intake of different carbohydrates,
The tumor-associated antigen MUC1 is a cell surface mucin that is expressed on the apical surface of most glandular epithelial cells, including the ducts of the breast, ovary, pancrease, lung and colon. During malignancy, epithelial tissues regularly display elevated levels of MUC1 in a non-polar
Interleukin-24 (IL-24), a cytokine belonging to the IL-10 family, can selectively induce apoptosis in a broad range of tumor cells without harming normal cells. The efficient and soluble expression of bioactive recombinant IL-24 in Escherichia coli remains an obstacle because of aggregation and
Three Streptomyces strains isolated from Guaviare sediments (Colombia, South America) with cytotoxic activity against prostate cancer (PC3), breast cancer (MDA-MB-231), and lung cancer (A549) line cells were studied. The present investigation reveals the enhancement of the cytotoxic activity
OBJECTIVE
To prepare mouse monoclonal antibodies (mAb) against AGR2 (human homolog of xenopus anterior gradient 2), to characterize these antibodies' properties, and to develop potential applications.
METHODS
BALB/c mice were immunized with AGR2-MBP (maltose binding protein) fusion protein. The mAb
Enzymatic blood glucose detection with selectivity is one of the most important conundrums, because human blood contains many components that can hinder enzyme-substrate reactions. Meanwhile, cancer cells express much higher levels of glucose transporter-1 on their cell membrane to selectively and
A short description selected from the presentations which had been awarded prizes in the 4th International Meeting of Nuclear Medicine, of the Hellenic Society of Nuclear Medicine, in Thessaloniki, Greece, is as follows: Professor L.G. Strauss from Heidelberg received the first prize for his
BACKGROUND
Chicken Anemia Virus (CAV) VP3 protein (also known as Apoptin), a basic and proline-rich protein has a unique capability in inducing apoptosis in cancer cells but not in normal cells. Five truncated Apoptin proteins were analyzed to determine their selective ability to migrate into the
The receptor protein-tyrosine phosphatase (PTP) DEP-1 (CD148/PTP-eta) has been implicated in the regulation of cell growth, differentiation, and transformation, and most recently has been identified as a potential tumor suppressor gene mutated in colon, lung, and breast cancers. We have generated
The Rep proteins of adeno-associated virus type 2 (AAV) are known to bind to Rep recognition sequences (RRSs) in the AAV inverted terminal repeats (ITRs), the AAV p5 promoter, and the preferred AAV integration site in human chromosome 19, called AAVS1. Integration of the AAV genome into AAVS1
Lasiodiplodan, an exopolysaccharide of the (1→6)-β-D: -glucan type, is produced by Lasiodiplodia theobromae MMPI when grown under submerged culture on glucose. The objective of this study was to evaluate lasiodiplodan production by examining the effects of carbon (glucose, fructose, maltose,
