Human ageing

Animals who defeated ageing.

Cellinsight Everything about human ageing and related diseases Immortal animals Nothing is forever in this world, death is certain, one day it will visit us. But there are some creatures that never die by natural aging process. Human cells are capable of dividing only 50 times, later the cells entered the senescence stage, and this is the exact reason for aging. Any animal which is not experiencing senescence can defeat ageing, today I am going to tell about such types of animals and how they live without the fear of ageing 1. Jelly fish (Turritopsis dohrnii)  Immortal jellyfish (Image credit goes to Wikimedia )  Jelly fishes are sea animals, included in the phylum coelenterata (cnideria). Turritopsis dohrnii is a species of jellyfish which is known as immortal jellyfish. Jellyfish reproduce both sexually and asexually.The life cycle consisted of three main stages, planulae,polyps and medusae. fertilized egg give birth to planula. The  Planula is the larval stage, after few da

Role of protein on aging 

Protein which controls the length of telomere are telomerase and a protein complex known as shelterin.a new study by Scripps Reserch Institute (TSRI) discovered a new protein named as TZAP (telomeric zinc associated protein)which decrease the length of telomeres by trimming,telomere is the clock of a biological cell,if it's length is too short the cell cannot multiply,a human cell can divide maximum 50 times,if it increase more, our life span may increase considerably.
Certain proteins undergo oxidisation which are known to be associated with ageing and some age related diseases,when people turn about 80 approximately half of the bady proteins are damaged due to oxidation,the oxidation occurs because of random chemical degradation,that are associated with convertion of food particles to energy ( metabolism) .
Protein's mis foldings are another reason for ageing,when native proteins are synthesised in our cells,which is in helical(Alfa helical)structure and everything fine,but in some cases the proteins produced are mis folded and which are considered as minimum energy state proteins,these proteins are useless or even toxic.these proteins are insoluble in water,where as good proteins are soluble,these mis folded proteins later form a long lenear aggregate known as amyloid diposit,these deposit causes diseases also,for example Alzheimer's disease.
