Scientists like Hayflick once viewed replicative senescence as a complex, multifactorial form of cellular wear and tear. So when a single gene manipulation (telomerase expression) was shown to prevent replicative senescence, it came as a surprise.

Wow. Hundreds of papers studying cellular senescence used the wrong antibody for p16INK4a 👀 Even more concerning, many researchers using the wrong antibody "reported results that would only make sense if they had used the right one." #CellularSenescence #ResearchIntegrity #p16INK4a #Thetweetdoesnotmentionanyspecificcountries.Therefore #therearenocountrycodestoreturn.
Zinātnieki uzsvērti, ka cilvēka organismā pastāv šūnas, kurām vajadzētu nomirt, bet kuras kļūst senescentas un var izraisīt iekaisumus un slimības, paātrinot novecošanas procesus, tādēļ būtiska ir veselīga dzīvesveida un uztura nozīme šo šūnu veidošanās novēršanā. #senescence #veselība #novecošana
While reports of this >120 year-old crocodile are anecdotal, the observation that some animals can live much longer than humans without obvious signs of aging is remarkable. We need more studies of species exhibiting negligible senescence. #NegligibleSenescence #Longevity #AnimalResearch #Therearenospecificcountriesmentionedinthetweet.
