    摘要: The present invention sterol-modified hedgehog polypeptides and functional fragments thereof Methods of identifying compositions which affect hedgehog activity based on inhibition of cholesterol modification of hedgehog protein are described. In one aspect of the invention, the method provides a means for affecting cholesterol biosynthesis or transport in a cell comprising contacting a cell with an effective amount of a compound that affects hedgehog, thereby affecting cholesterol biosynthesis or transport. The effect may be inhibition or stimulation of cholesterol biosynthesis or transport.

    摘要: The invention is specifically directed to efficient, random, simple insertion of a transposon or derivative transposable element into DNA in vivo or in vitro. The invention is particularly directed to mutations in ATP-utilizing regulatory transposition proteins that permit insertion with less target-site specificity than wild-type. The invention encompasses gain-of-function mutations in TnsC, an ATP-utilizing regulatory transposition protein that activates the bacterial transposon Tn7. Such mutations enable the insertion of a Tn7 transposon or derivative transposable element in a non-specific manner into a given DNA segment. Insertion can be effected in plasmid and cosmid libraries, cDNA libraries, PCR products, bacterial artificial chromosomes, yeast artificial chromosomes, mammalian artificial chromosomes, genomic DNAs, and the like. Such insertion is useful in DNA sequencing methods, for genetic analysis by insertional mutagenesis, and alteration of gene expression by insertion of a given genetic sequence.

    摘要: Methods, apparatuses, and systems for monitoring health of corneal tissue are disclosed. The system includes a corneal measurement device configured to measure a first state of health indicator that is tissue thickness or volume of a region of the corneal tissue during a first period of time and a second state of health indicator that is tissue thickness or volume of the region during a second period of time after the first period of time. The system further includes a processing unit configured to receive the first and second state of health indicators from the corneal measurement device and generate a health map of the region based on the first and second state of health indicators, the health map indicative of a change between the first and second state of health indicators as measured from the first period of time to the second period of time in the region of the cornea.
