PURPOSE Patients with luminal breast cancer (LBC) often become endocrine resistant over time. We investigated the molecular changes associated with acquired hormonoresistances in patient-derived xenografts of LBC. EXPERIMENTAL DESIGN Two LBC xenografts (HBCx22 and HBCx34) were treated with different endocrine treatments (ET) to obtain xenografts with acquired resistances to tamoxifen (TamR) a...
Genetic improvement programs may improve disease resistance in animal production. The best-characterized genetic control of disease resistance and immune response in animals is the one associated with the Major Histocompatibility Complex (MHC). The ovine lymphocyte antigenof DRB1 gene encodes cell surface glycoproteins that initiate immune responses by presenting processed antigenic peptides to...
این پژوهش به منظور شناسایی دامهای دارای مقاومت ژنتیکی نسبت به نماتود های دستگاه گوارش (gin) با استفاده از چندشکلیهای ریزماهوارهای موجود در ژن ovar-drb1 بره های نژاد قزل ایرانی طراحی شد. در پژوهش حاضر 120 بره نر قزل 4 تا 6 ماهه به صورت تصادفی از 6 گله گوسفند متفاوت در استان آذربایجان شرقی انتخاب شدند (تعداد 20 گوسفند در هر گله). این بره ها به صورت طبیعی با gin ها آلوده شده و نمونه های مدفوعی ...
the major histocompatibility complex (mhc) plays a central role in the control of disease resistance and immune response. extensive genetic diversity in mhc genes provides a valuable source for genetic improvement, via selection, in many domestic animals. exon 2 of the class ii mhc, termed ovar-drb1 in domestic sheep (ovis aries), has been suggested as important disease resistance and immune re...
