Any process that stops, prevents, or reduces the frequency, rate or extent of transcription mediated by RNA polymerase II.

Any process that stops, prevents or reduces the rate of addition of phosphate groups to amino acids within a protein.

Any process that decreases the frequency, rate or extent of gene expression. Gene expression is the process in which a gene's coding sequence is converted into a mature gene product or products (proteins or RNA). This includes the production of an RNA transcript as well as any processing to produce a mature RNA product or an mRNA or circRNA (for protein-coding genes) and the translation of that mRNA or circRNA into protein. Protein maturation is included when required to form an active form of a product from an inactive precursor form.

The chemical reactions and pathways performed by an organism resulting in the hydrolysis of proteins in another organism by cleavage of their peptide bonds.

Any process that stops, prevents, or reduces the frequency, rate or extent of signal transduction mediated by the MAPKKK cascade.

Any process in which an organism activates, maintains or increases the frequency, rate or extent of programmed cell death by apoptosis in a second organism.

Any process that modulates the rate, frequency, or extent of the chemical reactions and pathways resulting in the breakdown of a protein or peptide by hydrolysis of its peptide bonds that is mediated by the proteasome.

Any process that modulates the frequency, rate or extent of establishment of endothelial barrier.
