What's the difference between repress and repressible?

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.
