Justice for All? Issues Faced by Linguistic Minorities and Border Patrol Agents during Interpreted Arraignment Interviews.

2015

The Tijuana (Mexico) - San Ysidro (San Diego County, CA) international border is the world’s busiest port of entry. The US Customs and Border Protection Agency hires over 60,000 employees, 21,000 of whom are agents in the US Border Patrol. Several steps must be taken to become a border patrol agent, but being bilingual is not a pre-requisite. In order to communicate with detainees, and interrogate them, the US Border Patrol Agency hires the services of Telephone Interpreting Companies. In this study I present segments of a 2 hour and fifty minute transcript that captures a typical border patrol agent /detainee interaction facilitated by an ad-hoc interpreter. I examine the power differentia…

Heat shock response in yeast involver changes in both transcription rates and mRNA stabilities

2011

We have analyzed the heat stress response in the yeast Saccharomyces cerevisiae by determining mRNA levels and transcription rates for the whole transcriptome after a shift from 25uC to 37uC. Using an established mathematical algorithm, theoretical mRNA decay rates have also been calculated from the experimental data. We have verified the mathematical predictions for selected genes by determining their mRNA decay rates at different times during heat stress response using the regulatable tetO promoter. This study indicates that the yeast response to heat shock is not only due to changes in transcription rates, but also to changes in the mRNA stabilities. mRNA stability is affected in 62% of …

The Genotype of the Donor for the (GT)n Polymorphism in the Promoter/Enhancer of FOXP3 Is Associated with the Development of Severe Acute GVHD but Do…

2015

The FOXP3 gene encodes for a protein (Foxp3) involved in the development and functional activity of regulatory T cells (CD4+/CD25+/Foxp3+), which exert regulatory and suppressive roles over the immune system. After allogeneic stem cell transplantation, regulatory T cells are known to mitigate graft versus host disease while probably maintaining a graft versus leukemia effect. Short alleles (<=(GT)(15)) for the (GT)(n) polymorphism in the promoter/enhancer of FOXP3 are associated with a higher expression of FOXP3, and hypothetically with an increase of regulatory T cell activity. This polymorphism has been related to the development of auto-or alloimmune conditions including type 1 diabetes …

Genomic run-on evaluates transcription rates for all yeast genes and identifies gene regulatory mechanisms

2004

Most studies of eukaryotic gene regulation have been done looking at mature mRNA levels. Nevertheless, the steady-state mRNA level is the result of two opposing factors: transcription rate (TR) and mRNA degradation. Both can be important points to regulate gene expression. Here we show a new method that combines the use of nylon macroarrays and in vivo radioactive labeling of nascent RNA to quantify TRs, mRNA levels, and mRNA stabilities for all the S. cerevisiae genes. We found that during the shift from glucose to galactose, most genes undergo drastic changes in TR and mRNA stability. However, changes in mRNA levels are less pronounced. Some genes, such as those encoding mitochondrial pro…

2018

NtcA, es un factor de transcripción cianobacteriano perteneciente a la familia CRP. Es considerado el regulador global del nitrógeno en cianobacterias ya que presenta un regulón muy amplio que incluye muchos genes implicados en el metabolismo de nitrógeno. Se activa por 2-oxoglutarato(2-OG), un indicador del nivel de nitrógeno celular y es coactivado por una proteína llamada PipX, objeto importante de este estudio. A bajo nivel de 2-OG, PipX es secuestrada por la proteína señalizadora PII quedando inaccesible para activar NtcA. Sin embargo, la unión de 2-OG a PII en condiciones de escasez de nitrógeno, libera PipX, la cual queda accesible para coactivar NtcA. Las estructuras de NtcA unido a…

The relative importance of transcription rate, cryptic transcription and mRNA stability on shaping stress responses in yeast

2012

It has been recently stated that stress-responding genes in yeast are enriched in cryptic transcripts and that this is the cause of the differences observed between mRNA amount and RNA polymerase occupancy profiles. Other studies have shown that such differences are mainly due to modulation of mRNA stabilities. Here we analyze the relationship between the presence of cryptic transcripts in genes and their stress response profiles. Despite some of the stress-responding gene groups being indeed enriched in specific classes of cryptic transcripts, we found no statistically significant evidence that cryptic transcription is responsible for the differences observed between mRNA and transcription…

The distribution of active RNA polymerase II along the transcribed region is gene-specific and controlled by elongation factors.

2010

In order to study the intragenic profiles of active transcription, we determined the relative levels of active RNA polymerase II present at the 3'- and 5'-ends of 261 yeast genes by run-on. The results obtained indicate that the 3'/5' run-on ratio varies among the genes studied by over 12 log(2) units. This ratio seems to be an intrinsic characteristic of each transcriptional unit and does not significantly correlate with gene length, G + C content or level of expression. The correlation between the 3'/5' RNA polymerase II ratios measured by run-on and those obtained by chromatin immunoprecipitation is poor, although the genes encoding ribosomal proteins present exceptionally low ratios in …

There is a steady-state transcriptome in exponentially growing yeast cells

2010

The growth of yeast cells in batches in glucose-based media is a standard condition in most yeast laboratories. Most gene expression experiments are done by taking this condition as a reference. Presumably, cells are in a stable physiological condition that can be easily reproduced in other laboratories. With this assumption, however, it is necessary to consider that the average amount of the mRNAs per cell for most genes does not change during exponential growth. That is to say, there is a steady-state condition for the transcriptome. However, this has not been rigorously demonstrated to date. In this work we take several cell samples during the exponential phase growth to perform a kineti…

A genomic study of the inter-ORF distances in Saccharomyces cerevisiae.

2006

The genome of eukaryotic microbes is usually quite compacted. The yeast Saccharomyces cerevisiae is one of the best-known examples. Open reading frames (ORFs) occupy about 75% of the total DNA sequence. The existence of other, non-protein coding genes and other genetic elements leaves very little space for gene promoters and terminators. We have performed an in silico study of inter-ORF distances that shows that there is a minimum distance between two adjacent ORFs that depends on the relative orientation between them. Our analyses suggest that different kinds of promoters and terminators exist with regard to their length and ability to overlap each other. The experimental testing of some p…
