Calcifying aponeurotic fibroma (CAF) is a rare benign tumor that typically develops in the fascia and tendons. On MRI, CAF usually shows isointensity on T1WI and heterogeneous high intensity on T2WI. We report a case of 17-month-old girl with CAF on her right ankle. MRI showed an usual signal intensity for CAF. At 3 years and 4 months of age, MRI revealed hyperintense nodules on T1WI and T2WI i...

BACKGROUND Diabetes is the leading cause of CKD in the developed world. C-terminal fragment of agrin (CAF) is a novel kidney function and injury biomarker. We investigated whether serum CAF predicts progression of kidney disease in type 2 diabetics. METHODS Serum CAF levels were measured in 71 elderly patients with diabetic nephropathy using a newly developed commercial ELISA kit (Neurotune®)...

The removal of histones from DNA and their subsequent replacement is likely to be necessary for all processes that require access to the DNA sequence in eukaryotic cells. The histone chaperone chromatin assembly factor 1 (CAF-1) mediates histone H3-H4 assembly during DNA replication and nucleotide excision repair in vitro. We have found that budding yeast deleted for the genes encoding CAF-1 ar...

During infection, Yersinia pestis uses its F1 capsule to enhance survival and cause virulence to mammalian host. Since F1 is produced in large quantities and secreted into the host tissues, it also serves as a major immune target. To hold this detrimental effect under proper control, Y. pestis expresses the caf operon (encoding the F1 capsule) in a temperature-dependent manner. However, additio...

BACKGROUND Prostate cancer-associated fibroblasts (CAF) can stimulate malignant progression and invasion of prostatic tumour cells via several mechanisms including those active in extracellular matrix; METHODS We isolated CAF from prostate cancer patients of Gleason Score 6-10 and confirmed their cancer-promoting activity using an in vivo tumour reconstitution assay comprised of CAF and BPH1 ...

Arabidopsis thaliana floral meristems are determinate structures that produce a defined number of organs, after which cell division ceases. A new recessive mutant, carpel factory (caf), converts the floral meristems to an indeterminate state. They produce extra whorls of stamens, and an indefinite number of carpels. Thus, CAF appears to suppress cell division in floral meristems. The function o...

Chromatin assembly factor-1 (CAF-1), a complex consisting of p150, p60, and p48 subunits, is highly conserved from yeast to humans and facilitates nucleosome assembly of newly replicated DNA in vitro. To investigate roles of CAF-1 in vertebrates, we generated two conditional DT40 mutants, respectively, devoid of CAF-1p150 and p60. Depletion of each of these CAF-1 subunits led to delayed S-phase...

هدف: با توجه به کاستی‌های موجود، نظام سیاست‌گذاری سازمانی فرایندی سیستماتیک، هدفمند و منظم برای تولید داده‌های حاصل از عملکرد، پردازش آن‌ها اطلاعات تبدیل آن دانش سیاستی نیاز دارد تا نسبت کم کیف تحقق اهداف سیاست‌ها، آثار پیامدهای موفقیت یا ناکامی‌شان آگاهی داشته تصمیم‌گیری بهره گیرد. ازاین‌رو مسئله اصلی که محقق تلاش رفع می‌پردازد تبیین این موضوع است سیاست‌ها راهبردهای کلان چه پیامدها آثاری در پی...

Chromatin assembly factor 1 (CAF-1) was initially characterized as a histone deliver in the process of DNA-replication-coupled chromatin assembly in eukaryotic cells. Here, we report that CAF-1 p180, the largest subunit of Drosophila CAF-1, participates in the process of heterochromatin formation and functions to maintain pericentric heterochromatin stability. We provide evidence that Drosophil...
