زمینه و هدف: تزاید آنکوژن HER-2/neu (human epidermal growth factor receptor/ neuroglioblastoma) بر روی پیشرفت، درمان و پیشآگاهی سرطان سینه موثر است. بررسی دقیق وضعیت HER-2/neu بافت تومور، برای اداره بیماری و انتخاب صحیح بیماران پاسخگو به داروی جدید Trastuzumab مهم میباشد. این مطالعه با هدف بررسی وضعیت ژن HER-2/neu در نمونههای سرطان سینه توسط روش PCR تمایزی و تطابق موجود بین این روش با تست ای...
Lapatinib is a potent reversible and selective inhibitor of the tyrosine kinase domains of epidermal growth factor receptor and human epidermal growth factor receptor (HER)-2 that exerts its action by competitive binding to the intracellular ATP-binding site of the receptor. It is registered for the treatment of advanced or metastatic HER-2+ breast cancer in combination with capecitabine and fo...
Human epidermal growth factor receptor-2 (HER-2) is a well-established target for anticancer anticancerprecision medicine in humans. A HER-2 homologue with 92% amino acid identity has been described in canine mammary tumors, which whichis termed here as 'dog epidermal growth factor receptor-2 (DER-2)', with similar biological implications as those in human breast cancer. Both antigens can princ...
Breast cancer is the most common site-specific cancer and is the second cause of mortality due to cancer in women. There are different prognostic factors including: axillary nodal status and tumor size(the most important factor), ER activity, PR, tumor grade and the type of histology. Other incompletely defined risk factors are: protease, catepstin, Her-2, etc. Her-2 is subtype 2 of E...
To better understand the mechanisms of transformation by the oncogene HER-2, we transduced the human mammary epithelial (HME) cell line MCF-10A with HER-2 and developed a cell line that appeared to moderately overexpress HER-2. These MCF-10HER-2 cells were unable to grow in the absence of epidermal growth factor (EGF). However, coexpression of HER-2 with the HPV-16 oncoproteins E6 and E7 result...
this study focused on triple-negative breast cancer (tnbc) that is characterized by the lack of expression of estrogen receptor (er), progesterone receptor (pr), and human epidermal growth factor receptor 2 (her-2). the primary goal of this study was to describe the relation between triple-negative receptor status and survival. this is the first study about triple-negative breast cancer in our ...
A variety of eucaryotic polypeptide growth factors are synthesized as transmembrane precursors. Many of these precursors are released from plasma membranes by proteolytic cleavage and converted into soluble mature proteins. A number of studies, however, indicate that bound growth factor precursors can be biologically active, suggesting a role for these membrane-associated ligands in cell-cell c...
