Abstract:
Plants as sessile organisms have adapted highly sophisticated cellular processes to cope with environmental stress conditions, which include the initiation of complex transcriptional regulatory circuits. The heat shock transcription factors (HSFs) have been shown to be central regulators of plant responses to abiotic and biotic stress conditions. However, the extremely high multiplicity in plant HSF families compared to those of other kingdoms and their unique expression patterns and structures suggest that some of them might have evolved to become major regulators of other non-stress related

Abstract:
The CDP/Cux transcription factor is expressed as a 200 kDa protein that interacts rapidly and transiently with DNA. Proteolytic processing generates a shorter isoform, p110 CDP/Cux, that binds stably to DNA.

Transgenic mice expressing p110 CDP/Cux are more susceptible to different cancers.<br>CDP/Cux was originally described as a repressor of transcription. My goal was to verify whether CDP/Cux might

Abstract:
DNA methylation is an epigenetic mark that is deposited throughout the genome of mammals and plays an important role in the maintenance of transcriptionally repressive states across cell divisions. There are two major mechanisms by which DNA methylation has been proposed to act: one involves the recognition of the mark by protein complexes containing histone deacetylases (HDACs) that can remodel the local chromatin. Alternatively, methylation has been suggested to directly affect the interaction between transcription factors and their cognate binding sequence. The aim of this research was to d

Transcription-coupled nucleotide excision repair (TC-NER) removes bulky DNA lesions from the template strand at actively transcribed genes.

Therefore, there is considerable interest in understanding how repair is coupled to transcription.
