زمینه و هدف: خون بندناف در پیوند مغز استخوان، به علت دوز پایین سلول های cd34+ دارای محدودیت هایی است که می بایست این سلول ها مورد تزاید قرار گیرند. تکثیر سلول های بنیادی با استفاده از افزایش فعالیت خود تکثیری آن ها در شرایط آزمایشگاهی روی داربست dbm (ماتریکس استخوانی معدنی زدا شده) پوشیده شده با سلول های پروژنیتور مزانشیمی یعنی سلول های بنیادی سوماتیک غیر محدود شده (ussc) پیشنهاد می شود. مسیر t...
Variants in the TGFBR2 kinase domain cause several human diseases and can increase propensity for cancer. The widespread application of next generation sequencing within the setting of Individualized Medicine (IM) is increasing the rate at which TGFBR2 kinase domain variants are being identified. However, their clinical relevance is often uncertain. Consequently, we sought to evaluate the use o...
Although epithelial membrane protein 3 (EMP3) has been implicated as a candidate tumor suppressor gene for low grade glioma, its biological function in glioblastoma multiforme (GBM) still remains poorly understood. Herein, we showed that EMP3 was highly expressed in CD44-high primary GBMs. Depletion of EMP3 expression suppressed cell proliferation, impaired in vitro tumorigenic potential and in...
Conditional inactivation of Tgfbr2 in cranial neural crest causes cleft palate and calvaria defects.
Cleft palate and skull malformations represent some of the most frequent congenital birth defects in the human population. Previous studies have shown that TGFbeta signaling regulates the fate of the medial edge epithelium during palatal fusion and postnatal cranial suture closure during skull development. It is not understood, however, what the functional significance of TGFbeta signaling is i...
AIMS The expression patterns of TGFB signaling proteins, such as TGFB1/2, TGFBR1(ALK5), TGFBR2, SMAD1/2/3, SMAD2/3, SMAD4, SMAD7, and of downstream targets of TGFB signaling, CDKN1A (p21CIP1), CDKN1B (p27KIP1), MYC, CDC25A, TP53, and RELA (p65NF-kB) were investigated in gastric carcinomas and other gastric lesions. METHODS AND RESULTS A total of 112 gastric carcinomas, 37 dysplasias, 54 intes...
Transforming growth factor-B (TGF-B) plays complex dual roles as an inhibitor and promoter of tumor progression. Although the influence of the stromal microenvironment on tumor progression is well recognized, little is known about the functions of TGF-B signaling in the stroma during tumor progression. Using cre-lox technology, expression of the type II TGF-B receptor was selectively knocked ou...
BACKGROUND Regulatory T (Treg) cells, a subset of CD4+ T lymphocytes, are mediators of immunosuppression in cancer, and, thus, variants in genes encoding Treg cell immune molecules could be associated with ovarian cancer. METHODS In a population of 15,596 epithelial ovarian cancer (EOC) cases and 23,236 controls, we measured genetic associations of 1,351 SNPs in Treg cell pathway genes with o...
