Repression of transcription by altering the structure of chromatin, e.g. by conversion of large regions of DNA into an inaccessible state often called heterochromatin. Any process that is carried out at the cellular level, but not necessarily restricted to a single cell. For example, cell communication occurs among more than one cell, but occurs at the cellular level. Any transcriptional or post-transcriptional process carried out at the cellular level that results in long-term gene inactivation. Any process that activates or increases the frequency, rate or extent of a biological process. Biological processes are regulated by many means; examples include the control of gene expression, protein modification or interaction with a protein or substrate molecule. Any process that activates or increases the frequency, rate or extent of chromatin silencing at telomeres. Any cellular process that modulates the frequency, rate or extent of the chemical reactions and pathways involving nucleobases, nucleosides, nucleotides and nucleic acids. Any process that activates or increases the frequency, rate or extent of a cellular process, any of those that are carried out at the cellular level, but are not necessarily restricted to a single cell. For example, cell communication occurs among more than one cell, but occurs at the cellular level. Any process that modulates the rate, frequency, or extent of gene silencing, the transcriptional or post-transcriptional process carried out at the cellular level that results in long-term gene inactivation. Any epigenetic process that stops, prevents or reduces the rate of gene expression. Any process that modulates the frequency, rate or extent of a cellular process, any of those that are carried out at the cellular level, but are not necessarily restricted to a single cell. For example, cell communication occurs among more than one cell, but occurs at the cellular level. Any process that affects the rate, extent or location of chromatin silencing. Any process that increases the rate, frequency, or extent of the repression of transcription by methylation of DNA, leading to the formation of heterochromatin. Any process that increases the frequency, rate, or extent of chromatin silencing at silent mating-type cassette. Chromatin silencing at silent mating-type cassette is the repression of transcription at silent mating-type loci by altering the structure of chromatin. Any process that stops, prevents or reduces the frequency, rate or extent of cellular DNA-dependent transcription. Any process that increases the frequency, rate or extent of chromatin silencing at the centromere. Chromatin silencing at the centromere is the repression of transcription of centromeric DNA by altering the structure of chromatin. Any process that activates or increases the frequency, rate or extent of chromatin silencing. Any process that modulates the frequency, rate or extent of the synthesis of either RNA on a template of DNA or DNA on a template of RNA.
