It has been discovered that the stimulation of beta-adrenergic receptors, which activate cAMP formation, give rise to increased APP and GFAP synthesis in astrocytes. Hence, the in vitro or in vivo exposure of neuronal cells to certain compositions comprising beta-adrenergic receptor ligands or agonists, including, e.g., norepinephrine, isoproterenol and the like, increases APP mRNA transcription and consequent APP overproduction. These increases are blocked by beta-adrenergic receptor antagonists, such as propranolol. The in vitro or in vivo treatment of these cells with 8Br-cAMP, prostaglandin E2 (PG E2), forskolin, and nicotine ditartrate also increased APP synthesis, including an increase in mRNA and holoprotein levels, as well as an increase in the expression of glial fibrillary acidic protein (GFAP). Compositions and methods are disclosed of regulating APP overexpression and mediating reactive astrogliosis through cAMP signaling or the activation of beta-adrenergic receptors. It has further been found that the increase in APP synthesis caused by 8Br-cAMP, PG E2, or forskolin is inhibited by immunosuppressants, immunophilin ligands, or anti-inflammatory agents, such as cyclosporin A, and FK-506 (tacrolimus), as well as ion-channel modulators, including ion chelating agents such as EGTA, or calcium / calmodulin kinase inhibitors, such as KN93. The present invention has broad implications in the alleviation, treatment, or prevention of neurological disorders and neurodegenerative diseases, including Alzheimer's Disease.

A method for isolating a polynucleotide of interest that is present in the genome of a first mycobacterium strain and / or is expressed by the first mycobacterium strain, where the polynucleotide of interest is also absent or altered in the genome of a second mycobacterium strain and / or is not expressed in the second mycobacterium. The method includes (a) contacting the genomic DNA of the first mycobacterium strain under hybridizing conditions with the DNA of a least one clone that belongs to a bacterial artificial chromosome (BAC) genomic DNA library of the second mycobacterium strain, and (b) isolating the polynucleotide of interest that does not form a hybrid with the DNA of the second mycobacterium strain. This invention further pertains to a Mycobacterium tuberculosis strain H37Rv genomic DNA library, as well as a Mycobactetium bovis BCG strain Pasteur genomic DNA library, and the recombinant BAC vectors that belong to those genomic DNA libraries. This invention also relates to mycobacterial nucleic acids, and methods and kits for using these nucleic acids to detect mycobacteria in a biological sample.

The present invention relates to a method of inhibiting fibrosis in a patient. The method comprises administering a therapeutically effective amount of a somatostatin, a somatostatin agonist or a pharmaceutically acceptable salt thereof to said patent.

Disclosed are a method for treating an aging-related disease and a method for screening a therapeutic agent for an aging-related disease. The method for treating an aging-related disease includes administering to a subject a progerin expression inhibitor as an active ingredient. The method for screening a therapeutic agent for an aging-related disease includes selecting a candidate drug inhibitory of progerin expression.

The present invention relates to a method for identifying a non-competitive peptide, which inhibits the activity of a cytokine receptor. This method includes the steps of selecting a candidate peptide containing from about 7 to about 20 amino acids derived from a flexible region of a cytokine receptor, and determining the ability of the peptide to inhibit or promote the oligomerization and / or activation of the receptor by measuring an activity of the receptor in the absence or the presence of the candidate peptide, wherein the non-competitive peptide is selected when the activity of the receptor is measurably lower in the presence of the peptide as compared to in the absence of the peptide so identified. This invention also provides agonists of cytokine receptor activity. Pharmaceutical compositions that comprise the identified peptides are disclosed. Also disclosed are methods for treating patients with a disease or condition associated with abnormal cytokine receptor mediated function or activity such as inflammatory, autoimmune and vascular diseases.

The invention belongs to the field of Chinese medicines, and relates to a Chinese medicinal compound preparation for preventing and controlling chronic kidney disease and renal fibrosis and a preparation method thereof. On the basis of the theory of 'body resistance weakened while pathogenic factors prevailing, insufficiency of Qi and blood, and blood stasis and collaterals obstruction' in traditional Chinese medical science, the Chinese medicinal compound preparation is prepared from Chinese medicines such as Danshen root, angelica sinensis, peach kernel, twotooth achyranthes root and processed rhubarb. Through animal experiment and clinical trial, the Chinese medicinal compound preparation can improve renal haemodynamics, adjust lipid metabolic disturbance, enhance oxidation resistance, and inhibit over expression of cell factors so as to improve glomerulosclerosis and interstitial fibrosis degree, protect residual renal structures and functions, and delay the process of early-stage and medium-stage chronic renal failure deterioration. The Chinese medicinal compound preparation is particularly suitable for treating patients who suffer from chronic kidney disease (CKD2-4) and renal fibrosis which comprise renal insufficiency, proteinuria, atrophy of kidney and the like.
