Makoto Hayashi

Makoto earned his B.S., M.S., and his Ph.D. from Osaka University under the supervision of Dr. Hisao Masukata. During this period, he studied the mechanism of DNA replication in fission yeast and unexpectedly found that fission yeast heterochromatin protein Swi6/HP1 positively regulates DNA replication firing at pericentromere region. read more

Chromosome Instabilities

The ends of chromosomes are protected from unwanted enzymatic reactions by telomeres, structures composed of simple repeat sequences and associated proteins. In normal human somatic cells, telomere shortening during DNA replication eventually causes deprotection of telomeres, which activates DNA Damage Response (DDR) and halts cell division (replicative senescence). read more
