2017 MEDICINE NOBEL PRIZE FOR WORK ON
BIOLOGICAL CLOCKS
ഈ വര്ഷത്തെ(2017) വൈദ്യശാസ്ത്ര നൊബേല് പുരസ്കാരം പ്രഖ്യാപിച്ചു
Three Americans won the Nobel Prize in
Physiology or Medicine on
Monday for their discoveries about the body's daily rhythms, opening up whole
new fields of research and raising awareness about the importance of getting
proper sleep.Jeffrey C. Hall, Michael Rosbash and Michael W. Young won the
9-million-kronor ($1.1 million) prize for isolating a gene that controls the
body’s normal daily biological rhythm. Circadian rhythms adapt the workings of
the body to different phases of the day, influencing sleep, behavior, hormone
levels, body temperature and metabolism.They "were able to peek inside our
biological clock and elucidate its inner workings," the Nobel citation
said.
Mr. Rosbash is on the faculty at
Brandeis University, Mr. Young is at Rockefeller University and Mr. Hall has
been associated with the University of Maine.The winners have raised
"awareness of the importance of a proper sleep hygiene," said Juleen
Zierath of the Nobel academy. Michael Hastings, a scientist at the U.K. Medical
Research Council, said the discoveries had opened up a whole new field of study
for biology and medicine.“Until then, the body clock was viewed as a sort of
black box,” Mr. Hastings told The Associated Press. "We knew nothing about
its operation. But what they did was get the genes that made the body clock,
and once you've got the genes, you can take the field wherever you want
to.""It's a field that has exploded massively, propelled by the discoveries
by these guys," he told AP.The awardees’ work stems back to 1984, when Mr.
Rosbash and Mr. Hall, who was then also at Brandeis, along with Mr. Young
isolated the “period gene” in fruit flies. Mr. Hall and Mr. Rosbash found that
a protein encoded by the gene accumulated during the night and degraded during
daytime. A decade later, Mr. Young discovered another "clock gene."
Paradigm-shifting
findings
"The paradigm-shifting discoveries by the laureates
established key mechanisms for the biological clock," the Nobel Assembly
said in its prize statement.
"Our wellbeing is affected when there is a temporary
mismatch between our external environment and this internal biological clock,
for example when we travel across several time zones and experience 'jet lag,'”
the statement said. "There are also indications that chronic misalignment
between our lifestyle and the rhythm dictated by our inner time keeper is
associated with increased risk for various diseases."
ഈ വര്ഷത്തെ വൈദ്യശാസ്ത്ര നൊബേല് പുരസ്കാരം പ്രഖ്യാപിച്ചു. മൂന്ന് പേര്ക്കാണ് ഇത്തവണ പുരസ്കാരം ലഭിച്ചത്. ജഫ്രി സി ഹാള്, മൈക്കല് റോസ്ബാഷ്, മൈക്കല് യങ് എന്നിവര്ക്കാണ് പുരസ്കാരം.ബയോളജിക്കല് ക്ലോക്ക് അടിസ്ഥാനമാക്കിയുള്ള കണ്ടുപിടിത്തങ്ങള്ക്കാണ് പുരസ്കാരം
