study of cohesive devices in the textbook of english for the students of apsychology by rastegarpour
this study investigates the cohesive devices used in the textbook of english for the students of psychology. the research questions and hypotheses in the present study are based on what frequency and distribution of grammatical and lexical cohesive devices are. then, to answer the questions all grammatical and lexical cohesive devices in reading comprehension passages from 6 units of 21units th...
Immune abnormalities in avian erythroblastosis virus-infected chickens.
Infection of animals with retroviruses frequently leads to immunosuppressed states. The immune status of chickens injected with the replication-defective avian erythroblastosis virus (AEV), with its naturally occurring subgroup B helper virus (avian erythroblastosis-associated virus; AEAV), was evaluated daily and compared to the immune status of age-matched uninfected control chickens. Spleen ...
متن کاملAvian erythroblastosis virus E26: only one (myb) of two cell-derived coding regions is necessary for oncogenicity.
The oncogene hypothesis postulates that mutated cellular genes, termed proto-onc genes, function as cancer genes because they are related to retroviral onc genes. However, in contrast to retroviral onc genes, mutated proto-onc genes from cancers are not sufficient for carcinogenesis. Therefore, it has been proposed that mutated proto-onc genes depend on other proto-onc genes for carcinogenesis....
متن کاملETS 2 ( v - ets erythroblastosis virus E 26 oncogene homolog 2 ( avian ) )
Structural analysis of the Ets2 promoter has revealed the absence of TATA and CAAT boxes, thus allowing transcription initiation from multiple start sites (Papas et al., 1990a). The first Intron of Ets2 also contains transcriptional initiation sequences, facilitating transcription. These sequences may compensate for the absence of TATA and CAAT sites within the promoter (Begue et al., 1997). Th...
متن کاملTranscription factor avian erythroblastosis virus E26 oncogen homolog-1 is a novel mediator of renal injury in salt-sensitive hypertension.
Transcription factor E26 transformation-specific sequence-1 (ETS-1) is a transcription factor that regulates the expression of a variety of genes, including growth factors, chemokines, and adhesion molecules. We recently demonstrated that angiotensin II increases the glomerular expression of ETS-1 and that blockade of ETS-1 ameliorates the profibrotic and proinflammatory effects of angiotensin ...
