This study compared caffeine pharmacokinetics, glycerol concentrations, metabolic rate, and performance measures following ingestion of a time-release caffeine containing supplement (TR-CAF) versus a regular caffeine capsule (CAF) and a placebo (PL). Following a double-blind, placebo-controlled, randomized, cross-over design, ten males (25.9 ± 3.2 y) who regularly consume caffeine ingested caps...

BACKGROUND The C-terminal agrin fragment (CAF) is a cleavage product of agrin, the major proteoglycan of the glomerular basement membrane. This article studies if CAF could serve as a biomarker for renal function in renal transplant recipients. MATERIAL AND METHODS We measured serum CAF and creatinine concentrations and calculated estimated glomerular filtration rate (eGFR) (MDRD) in 96 healt...

P/CAF is a histone acetyltransferase enzyme which was originally identified as a CBP/p300-binding protein. In this manuscript we report that human P/CAF is acetylated in vivo. We find that P/CAF is acetylated by itself and by p300 but not by CBP. P/CAF acetylation can be an intra- or intermolecular event. The intermolecular acetylation requires the N-terminal domain of P/CAF. The intramolecular...

De novo chromatin assembly maintains histone density on the daughter strands in the wake of the replication fork. The heterotrimer chromatin assembly factor 1 (CAF-1) couples DNA replication to histone deposition in vitro, but is not essential for yeast cell proliferation. Depletion of CAF-1 in human cell lines demonstrated that CAF-1 was required for efficient progression through S-phase. Cell...

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...
