(Submitter supplied) Detection, treatment, and prediction of outcome for lung cancer patients increasingly depend on a molecular understanding of tumor development and sensitivity of lung cancer to therapeutic drugs. The application of genomic technologies, such as microarray, is widely used to monitor global gene expression and has built up invaluable information and knowledge, which is essential to the discovery of new insights into the mechanisms common to cancer cells, resulting in the identification of unique, identifiable signatures and specific characteristics. more...

(Submitter supplied) The alkylating agent N-methyl-N’-nitro-N-nitrosoguanidine (MNNG) induces cellular DNA damages and other comprehensive alterations that lead to chromosomal aberrations, mutations, tumor initiations, and cell death. However, the molecular mechanism of MNNG-induced cellular stress remains unclear.We have genome-wide analyzed early transcriptional responses of human FL amnion epithelial cells after exposure to three relatively low doses of MNNG (0.2, 1.0, and 10.0µM),and differential gene expression profiles were obtained 4 h after exposure using oligonucleotide microarrays followed by validation with quantitative real-time RT-PCR. more...

(Submitter supplied) PURPOSE. Triamcinolone acetonide (TA) and dexamethasone (DEX) are corticosteroids commonly used for ocular inflammation but both can cause ocular hypertension. We investigated the differential gene expression profile of human trabecular meshwork (TM) cells in response to treatment by TA compared to that by DEX. METHODS. Total RNA was extracted from cultured human TM cells treated with TA or DEX and used for microarray gene expression analysis. more...

(Submitter supplied) d-serine is naturally present throughout the human body. It is also used as add-on therapy for treatment-refractory schizophrenia. d-Serine interacts with the strychnine-insensitive glycine binding site of NMDA receptor, and this interaction could lead to potentially toxic activity (i.e., excitotoxicity) in brain tissue. The transcriptomic changes that occur in the brain after d-serine exposure have not been fully explored. more...

(Submitter supplied) Develop of the heart during perinatal period must involve the differentially expression of a myriad of genes. We can think about the developmental events of heart formation in the context of genetic networks. However the knowledge of the genetic basis in governing and regulating of this development is still partial and scattered; an overall elucidation of the differential expressed genes blueprint before and after birth has never been proposed. more...

(Submitter supplied) Prostaglandin F2 alpha (PGF2alpha) brings about regression of the bovine corpus luteum (CL). This luteolytic property of PGF2alpha is used in the beef and dairy cattle to synchronize estrus. A limitation of this protocol is an insensitivity of the early CL to luteolytic actions of PGF2alpha. The mechanisms underlying luteal sensitivity (LS) are poorly understood. The early CL has maximum number of PGF2alpha receptors; therefore differences in signaling events might be responsible for LS. more...

(Submitter supplied) Human LATS1 and LATS2 (LATS1/2) are tumor suppressors that have been shown to be mutated or downregulated in several human cancers including leukemia, lung, prostate and breast cancers. However, the precise mechanisms and the proteins modulated by LATS1/2 that are responsible for these events remain largely unknown. To elucidate potential signaling pathways, the current study investigated the expression profile in HeLa cells with reduced expression of LATS1/2. more...

The corneal epithelial stem cells are believed to reside at the limbus. The intrinsic and external molecular signals that modulate the differentiation and proliferation of the limbal stems cells are still largely unidentified because of a lack of known specific markers. more...

Transcription of the non-coding (antisense) strands of some of the CfMNPV select genes including the polyhedrin gene was also detected by the array analysis. The expression of four host genes varied several fold throughout virus infection. more...

(Submitter supplied) Although major differences in the response of tissues were documented in the literature, the molecular mechanisms underlying tissue radiosensitivity are still fragmentary and need to be study more thoroughly. To this end, a genome wide analysis strategy was used to investigate changes in gene expression in the liver following exposition to ionizing radiation. This follows the tissue survey that was previously initiated with other organs and tends to obtain a comprehensive picture of the molecular events underlying tissue radio sensitivity. more...
