In vitro transcription from the Escherichia coli ilvIH promoter.
Description :
Lrp (leucine-responsive regulatory protein) activates the expression of the Escherichia coli ilvIH operon in vivo and mediates the repression of the operon by exogenous leucine. In previous studies, operon expression in vivo was measured with transcriptional fusions of lacZ to the ilvIH promoter. He...

Lrp, a major regulatory protein in Escherichia coli, bends DNA and can organize the assembly of a higher-order nucleoprotein structure.
Description :
Lrp (Leucine-responsive regulatory protein) is a global regulatory protein that controls the expression of many operons in Escherichia coli. One of those operons, ilvIH, contains six Lrp binding sites located within a several hundred base pair region upstream of the promoter region. Analysis of the ...

Postnatal evolution of the rat pineal gland: light microscopy.
Description :
The postnatal development and morphology of the adult albino rat pineal gland was studied from one day up to ten months of age. During postnatal life there was a marked increase in gland and pinealocyte volume, more intense during the first 45 days. After ten days, the differences in nuclear morphol...

Ultrastructure of the pineal gland in the adult rat.
Description :
The ultrastructure of the rat pineal gland was studied from 75 days until 10 months of age. Type I pinealocytes of young adults showed nuclei with dispersed chromatin, numerous infoldings of the nuclear envelope and well developed nucleoli. The cytoplasm displayed many mitochondria and clusters of s...

Oxytalan fibres in the rat pineal gland.
Description :
The present study shows the existence of oxytalan fibres in the connective tissue spaces of the rat pineal gland. The identification of these fibres with light microscopy is based on their ability to stain with aldehyde-fuchsin and orcein after oxidation with peracetic acid. Using the electron micro...

Postnatal development of cell types in the rat pineal gland.
Description :
The morphological development of the rat pineal gland has been studied from 1 to 60 days of age. During the first days, undifferentiated cells (pinealoblasts) with scanty cytoplasm and frequent mitotic figures were observed. The differentiation of cell types (Types I and II pinealocytes) began on th...
