Abstract: We used hierarchical clustering to examine gene expression profiles generated by serial analysis of gene expression (SAGE) in a total of nine normal lung epithelial cells and non-small cell lung cancers (NSCLC). Separation of normal and tumor samples, as well as histopathological subtypes, was evident using the 3,921 most abundant transcript tags. This distinction remained when just 115 highly differentially expressed transcript tags were used. Furthermore, these 115 transcript tags clustered into groups that were suggestive of the unique biological and pathological features of the different tissues examined. Adenocarcinomas were characterized by high-level expression of small airway-associated or immunologically related proteins, while squamous cell carcinomas overexpressed genes involved in cellular detoxification or antioxidation.

Abstract: This invention provides methods for treating a mycobacterial infection by administering to an animal a pharmaceutical composition containing a compound having the formula R—SOn-Z-CO—Y, where R is an alkyl group having 6-20 carbons; Z is a radical selected from —CH2—, —O—, and —NH—, two of these radicals coupled together, or —CH2═CH2—; Y is —NH2, O—CH2—C6H5, —CO—CO—O—CH3, or O—CH3; and n is 1 or 2. It has been discovered that these compounds inhibit growth of microbial cells which synthesize &agr;-substitued. &bgr;-hydroxy fatty acids, particularly corynemycolic acid, nocardic acid, and mycolic acid. These compounds may be used to inhibit growth of mycobacterial cells, such as Mycobacterium tuberculosis, drug-resistant M. tuberculosis, M. avium intracellulare, and M. leprae.

Abstract: A novel protein, fibroblast growth factor homologous factor-1 (FHF-1), the polynucleotide sequence encoding FHF-1, and the deduced amino acid sequence are disclosed. Also disclosed are diagnostic and therapeutic methods of using the FHF-1 polypeptide and polynucleotide sequences and antibodies which specifically bind to FHF-1.
