Long-Term Assessment of AAV-Mediated Zinc Finger Nuclease Expression in the Mouse Brain.

Gene editing tools like TALENs, ZFNs and Crispr/Cas now offer unprecedented opportunities for targeted genetic manipulations in virtually all species. Most of the recent research in this area has concentrated on manipulation of the genome in isolated cells, which then give rise to transgenic animals or modified stem cell lines. Much less is known about applicability of genetic scissors in terminally differentiated, non-dividing cells like neurons of the adult brain.

Dermatomycoses: challenges and human immune responses.

The most prevalent skin infections are mainly caused by species of dermatophytes of the genera Trichophyton, Microsporum, and Epidermophyton that infect keratinized tissues and stratum corneum of skin and hair. Besides proteases with putative role of kinases and other enzymes, immune modulators are abundantly secreted during infection as well. The molecular mechanism used by the dermatophytes to infect and counteract the host immune response is not well understood.

Plant-bacterium interactions analyzed by proteomics.

The evolution of the plant immune response has resulted in a highly effective defense system that is able to resist potential attack by microbial pathogens. The primary immune response is referred to as pathogen associated molecular pattern (PAMP) triggered immunity and has evolved to recognize common features of microbial pathogens. In response to the delivery of pathogen effector proteins, plants acquired R proteins to fight against pathogen attack.

Identification of novel autoantigen in the synovial fluid of rheumatoid arthritis patients using an immunoproteomics approach.

Rheumatoid arthritis (RA) is a chronic, autoimmune and inflammatory joint disease with a poorly understood etiology. Despite widespread diagnostic use of anti-citrullinated protein antibodies and rheumatoid factor proteins there is a strong demand for novel serological biomarkers to improve the diagnosis this disease. The present study was aimed to identify novel autoantigens involved in rheumatoid arthritis (RA) pathogenesis through immune-proteomic strategy.

Gossypium arboreum GHSP26 enhances drought tolerance in Gossypium hirsutum.

Heat-shock proteins (HSP) are molecular chaperones for protein molecules. These proteins play an important role in protein-protein interactions such as, folding and assisting in the establishment of proper protein conformation and prevention of unwanted protein aggregation. A small HSP gene GHSP26 present in Gossypium arboreum responds to dehydration.

[Isolation and functional analysis of cotton universal stress protein promoter in response to phytohormones and abiotic stresses].

The 949 bp promoter fragment upstream from the translation initiation site of the GUSP gene encoding a universal stress protein was isolated from the genomic DNA of Gossypium arboream. Some putative cis-acting elements involved in stress responses including E-box, ABRE, DPBF-box, and MYB-core elements were found in the promoter region. In an Agrobacterium-mediated transient expression assay, strong activation of the GUSP full promoter region occurred in tobacco leaves following dehydration, abscisic acid, salt, heavy metal, gibberellic acid and dark treatments.

RNAi as a new therapeutic strategy against HCV.

Hepatitis C virus is a major cause of liver associated diseases all over the world. Irrespective of the significant advances in the current therapy, drugs and vaccines are restricted with many factors such as toxicity, complexity, cost and resistance. New technologies particularly RNA interference (RNAi) mediated by small interfering RNA (siRNA) have become more and more interesting and effective therapeutic entities to silence pathogenic gene products associated with disease, including cancer, viral infections and autoimmune disorders.

Functional analysis of cotton small heat shock protein promoter region in response to abiotic stresses in tobacco using Agrobacterium-mediated transient assay.

The cotton (Gossypium arboreum) stress-related gene GHSP26 responds to dehydration. To elucidate its stress tolerant mechanism at the transcriptional level, we isolated and characterized the promoter region (PGHSP26, -2,831 bp) flanking the 5' GHSP26 coding region from the genomic DNA. A series of PGHSP26 deletion derivatives was created for the identification of the upstream region of the gene required for the promoter activity.
