What's the difference between repress and represser?
Repress
Definition:
(v. t.) To press again.
(v. t.) To press back or down effectually; to crush down or out; to quell; to subdue; to supress; as, to repress sedition or rebellion; to repress the first risings of discontent.
(v. t.) Hence, to check; to restrain; to keep back.
(n.) The act of repressing.
Example Sentences:
(1) When micF was cloned into a high-copy-number plasmid it repressed ompF gene expression, whereas when cloned into a low-copy-number plasmid it did not.
(2) Cellulase regulation appears to depend upon a complex relationship involving catabolite repression, inhibition, and induction.
(3) The sexual dimorphism in hepatic drug metabolism found in Crl:CD-1 mice is due to the normally repressive effects of testicular androgens on the activities of hepatic monooxygenases.
(4) Faisal Abu Shahla, a senior official in Fatah, an organisation responsible for a good deal of repression of its own when it was in power, accuses Hamas of holding 700 political prisoners in Gaza as part of a broad campaign to suppress dissent.
(5) Transcription studies in vitro on repression of the tryptophan operon of Escherichia coli show that partially purified trp repressor binds specifically to DNA containing the trp operator with a repressor-operator dissociation constant of about 0.2 nM in 0.12 M salt at 37 degrees , a value consistent with the extent of trp operon regulation in vivo.
(6) At follow-up, the initial presence of signs of repression was significantly more common in such initially nonregressive patients as had escaped a later psychotic breakdown.
(7) The direct physical interaction of p300 with enhancer elements provides a biochemical basis for the genetic evidence linking the E1A-mediated enhancer repression function with the p300-binding activity of E1A.
(8) In contrast, BTEB repressed the activity of a promoter containing BTE, a single GC box of the CYP1A1 gene that is stimulated by Sp1.
(9) The Chinese model of development, which combines political repression and economic liberalism, has attracted numerous admirers in the developing world.
(10) Evidence is presented in support of a model for catabolite repression of the operon which involves a negative-acting transcriptional regulator which binds to the promoter region of the operon and prevents transcription.
(11) The paper postulates that 'anal or sphincter defensiveness' is one of the precursors of the repression barrier.
(12) Thus, the T cell-dependent suppression of IgE synthesis in B53 cells correlates with a specific inactivation of the immunoglobulin heavy chain enhancer, strongly suggesting that T cell-mediated suppression of Ig synthesis can normally occur through specific repression of Ig enhancer function.
(13) For example, it appears that homeotic genes expressed in posterior regions of the embryo (such as abd-A and Abd-B) repress the expression of those homeotic genes expressed in more anterior regions (such as Antp and Ubx).
(14) Although B12 supplementation results in a 10-fold repression of metE-lacZ expression, homocysteine addition to the growth medium overrides the B12-mediated repression.
(15) The cells show a repressed phenotype for IE expression but can be induced by inhibition of protein synthesis.
(16) Russia has no national museum of Stalin's repression but Moscow has two Gulag museums.
(17) Both genes are expressed in the fetal liver, gut, and visceral endoderm of the yolk sac and are repressed shortly after birth in the liver and gut.
(18) With glucose as a substrate, 2-deoxyglucose showed a strong permanent repression of M protein synthesis, whereas both glucose and 2-deoxyglucose caused temporary repression when sucrose was the substrate.
(19) It postulated that this competition is effectuated through the repression of the B cell function by the T1 lymphocyte killer effectors of the DH committed to the same antigen against which the "blasts" or the plasmoblasts (subsequently transformed into MC) were produced.
(20) Thus, constitutive expression of specific cytochrome P450 genes is repressed or activated in senescent rats.
