Interactions of caffeine with chemicals known for their effects on chromosomal segregation during meiosis of Saccharomyces cerevisiae were studied. It appears that caffeine does interfere with the action of other compounds during the different phases of meiosis. Treatments with methyl methanesulphonate (MMS) and cadmium chloride (CdCl2) resulted in a synergistic effect consisting of an increase in the frequency of recombination. The greatest effects were found on the induction of diploid spores: MMS, hycanthone, and distamycin demonstrated strong, benlate little synergistic action. CdCl2 demonstrated antagonism to caffeine by counter-inhibiting its effect on the induction of diploids. Concerning disomic induction: caffeine reduced (or left unchanged) the effect on non-disjunction when MMS and hycanthone were used. Simple additive effects were caused in conjunction with distamycin, benlate, and (in small doses) CdCl2. 2 mg of caffeine/ml in treatments with CdCl2 resulted in a very high frequency of disomic clones.

UI MeSH Term Description Entries
D008540 Meiosis A type of CELL NUCLEUS division, occurring during maturation of the GERM CELLS. Two successive cell nucleus divisions following a single chromosome duplication (S PHASE) result in daughter cells with half the number of CHROMOSOMES as the parent cells.

D008741 Methyl Methanesulfonate An alkylating agent in cancer therapy that may also act as a mutagen by interfering with and causing damage to DNA. Methylmethane Sulfonate,Dimethylsulfonate,Mesilate, Methyl,Methyl Mesylate,Methyl Methylenesulfonate,Methylmesilate,Mesylate, Methyl,Methanesulfonate, Methyl,Methyl Mesilate
D008937 Mitomycins A group of methylazirinopyrroloindolediones obtained from certain Streptomyces strains. They are very toxic antibiotics used as ANTINEOPLASTIC AGENTS in some solid tumors. PORFIROMYCIN and MITOMYCIN are the most useful members of the group.
D001761 Bleomycin A complex of related glycopeptide antibiotics from Streptomyces verticillus consisting of bleomycin A2 and B2. It inhibits DNA metabolism and is used as an antineoplastic, especially for solid tumors.

D002104 Cadmium An element with atomic symbol Cd, atomic number 48, and atomic weight 112.41. It is a metal and ingestion will lead to CADMIUM POISONING.
D002110 Caffeine A methylxanthine naturally occurring in some beverages and also used as a pharmacological agent. Caffeine's most notable pharmacological effect is as a central nervous system stimulant, increasing alertness and producing agitation. It also relaxes SMOOTH MUSCLE, stimulates CARDIAC MUSCLE, stimulates DIURESIS, and appears to be useful in the treatment of some types of headache. Several cellular actions of caffeine have been observed, but it is not entirely clear how each contributes to its pharmacological profile. Among the most important are inhibition of cyclic nucleotide PHOSPHODIESTERASES, antagonism of ADENOSINE RECEPTORS, and modulation of intracellular calcium handling. 1,3,7-Trimethylxanthine,Caffedrine,Coffeinum N,Coffeinum Purrum,Dexitac,Durvitan,No Doz,Percoffedrinol N,Percutaféine,Quick-Pep,Vivarin,Quick Pep,QuickPep
D002875 Chromosomes In a prokaryotic cell or in the nucleus of a eukaryotic cell, a structure consisting of or containing DNA which carries the genetic information essential to the cell. (From Singleton & Sainsbury, Dictionary of Microbiology and Molecular Biology, 2d ed) Chromosome
