Any process that activates or increases the frequency, rate or extent of ergosterol biosynthesis by activating or increasing the frequency, rate or extent of transcription from an RNA polymerase II promoter.

A positive regulation of transcription from RNA polymerase II promoter that results in positive regulation of filamentous growth of a population of unicellular organisms in response to starvation.

A positive regulation of transcription from RNA polymerase II promoter that results in positive regulation of filamentous growth of a population of unicellular organisms in response to starvation.

Any process that activates or increases the frequency, rate or extent of sterol import by activating or increasing the frequency, rate or extent of transcription from an RNA polymerase II promoter.

Any process that activates or increases the frequency, rate or extent of transcription from an RNA polymerase II promoter.

Any process that activates or increases the frequency, rate or extent of sterol import by activating or increasing the frequency, rate or extent of transcription from an RNA polymerase II promoter.

Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a stimulus indicating lowered oxygen tension. Hypoxia, defined as a decline in O2 levels below normoxic levels of 20.8 - 20.95%, results in metabolic adaptation at both the cellular and organismal level.

The chemical reactions and pathways resulting in the formation of ergosterol, (22E)-ergosta-5,7,22-trien-3-beta-ol, a sterol found in ergot, yeast and moulds.

Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a drug stimulus. A drug is a substance used in the diagnosis, treatment or prevention of a disease.

A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent.

A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it.

Cytoplasm situated near, or occurring around, the nucleus.

All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
