1999 journal article

In yeast, upc2-1 confers a decrease in tolerance to LiCl and NaCl, which can be suppressed by the P-type ATPase encoded by ENA2

DNA AND CELL BIOLOGY, 18(2), 133–139.

By: F. Leak n, S. Tove* & L. Parks*

MeSH headings : Adenosine Triphosphatases / genetics; Cholesterol / pharmacokinetics; Dose-Response Relationship, Drug; Genes, Fungal / genetics; Genetic Complementation Test; Lithium Chloride / pharmacology; Mutation; Saccharomyces cerevisiae / drug effects; Saccharomyces cerevisiae / genetics; Saccharomyces cerevisiae / metabolism; Saccharomyces cerevisiae Proteins; Sodium Chloride / pharmacology; Sterols / pharmacokinetics; Trans-Activators / genetics
TL;DR: Wild-type yeast cells are unable to take up sterols from their growth media under aerobic conditions and are relatively resistant to monovalent cations, but a yeast mutant with a defect in the aerobic exclusion of sterols was found to have increased sensitivity to LiCl and NaCl.

CURRENT GENETICS, 34(2), 93–99.

By: J. Crowley n, S. Tove n & L. Parks n

author keywords: ergosterol; antifungal; calcium; fenpropimorph; azole; ERG24 gene
MeSH headings : Antifungal Agents / pharmacology; Calcium / metabolism; Calcium / pharmacology; Culture Media; Ergosterol / analogs & derivatives; Ergosterol / biosynthesis; Ergosterol / genetics; Ergosterol / metabolism; Genes, Fungal; Morpholines / pharmacology; Mutation; Oxidoreductases / genetics; Oxidoreductases / metabolism; Phenotype; Saccharomyces cerevisiae / drug effects; Saccharomyces cerevisiae / genetics; Saccharomyces cerevisiae / metabolism
TL;DR: A novel calcium-dependent phenotype associated with alterations in the ergosterol biosynthetic pathway in yeast is described and reduction of yeast growth with an azole inhibitor of the C-14 sterol de-methylase was also modulated by an excess of calcium ions in the culture medium.

Yeast, 13(5), 449–462.

By: M. Tomeo n, L. Palermo n, S. Tove n & L. Parks n

TL;DR: Two temperature‐conditional secretory mutations, sec1 and sec5, cause the accumulation of post‐Golgi vesicles when strains containing these mutations are grown at 37°C, and double mutants containing sec6, sec14 or sec18 with either a sec1 or sec5 mutation have normal esterification levels.

TL;DR: A general trend was seen in which the earlier in the biosynthetic pathway that a mutation occurred, the less able the strain producing the defective sterols could compete with the ergosterol-producing strains. (via Semantic Scholar)
