摘要:
Non-tumorigenic, human bronchial epithelial cell lines are provided wherein the cell lines are capable of expressing cytochrome P450 genes which have been inserted into the cell lines. Also provided are methods and kits for identifying potential mutagens, cytotoxins, carcinogens, and chemotherapeutic agents utilizing these cell lines.
摘要:
A method of synthesizing double-stranded DNA sequences is disclosed. The method comprises the steps of:
(a) preparing a first series of oligodeoxyribonucleotide fragments which, when joined in proper sequence, form a DNA coding strand; (b) preparing a second series of oligodeoxyribo- nucleotide fragments which, when joined in proper sequence, form a DNA strand complementary to the coding strand; (c) compelling hydrogen bonding and ligation in proper sequence between the first and second series of oligodeoxyribonucleotide fragments prepared in steps (a) and (b) in a single reaction to produce the entire double-stranded DNA sequence; (d) treating the double-stranded DNA sequence with one oligonucleotide primer for each strand under hybridizing conditions; (e) polymerizing an extension product of each primer that is complementary to each strand of the double-stranded DNA sequence which is a template for forming the primer extension product; (f) denaturing the product of step (e) to separate the primer extension products from their respective templates to form four separate single-stranded DNA sequences; (g) treating the denatured product of (f) with oligonucleotide primers, such that a primer extension product is synthesized using each of the single strands produced in step (f) as a template resulting in amplification of the double-stranded DNA sequence; and (h) repeating steps (d), (e), (f) and (g) until the desired quantity of the double-stranded DNA sequence is formed.
摘要:
Description est faite de peptides pharmacologiquement actifs uniques en leur genre, ayant la formule générale (I), dans laquelle Tyr représente acide-aminé tyrosine, Pro représente l'amino-acide proline, Phe représente l'amino-acide phénylalanine, Thr représente l'amino-acide thréonine, A, B, C, D et E peuvent être n'importe quels amino-acides désirés de la forme D ou L. T représente la fonction acide à terminal C et sa modification. Les composés conviennent au traitement des maladies.

摘要:
The present invention relates to an isolated human hematopoietic stem cell or progenitor cell, transduced with a lentiviral vector which comprises a coding nucleic acid sequence encoding a functional variant of a polypeptide selected from gp91phox, p22phox, p40phox, p47phox, p67phox and Rac2; under transcriptional control of a promoter sequence that comprises or essentially consists of the miR223 promoter sequence (SEQ ID NO 01).
