Ko te Alpha-ketoglutarate (AKG) he takawaenga pākia nui e whai wāhi nui ana ki te tinana tangata, inā koa ki te pākia o te pūngao, te urupare ārai mate, me te whakatikatika pūtau.
I ngā tau tata nei, kua arohia a AKG mō tōna kaha ki te whakaroa i te koroheketanga me te rongoā i ngā mate pūmau. Anei ngā tikanga mahi motuhake a AKG i roto i ēnei tukanga:
He maha ngā mahi a AKG i roto i te whakatikatika i te DNA, e āwhina ana ki te pupuri i te pono o te DNA mā roto i ēnei ara:
Hei tauhohenga mō ngā tauhohenga hydroxylation: He tauhohenga a AKG mō te maha o ngā dioxygenases (pērā i ngā whākōkī TET me ngā whākōkī PHD).
Ka whai wāhi ēnei whākōkī ki te tango i te methylation o te DNA me te whakarerekētanga o te histone, hei pupuri i te pumau o te ira me te whakahaere i te whakaaturanga ira.
Ka whakahohehia e te whākōkī TET te tangohanga o te 5-methylcytosine (5mC) ka huri hei 5-hydroxymethylcytosine (5hmC), ā, mā reira ka whakahaeretia te whakaaturanga ira.
Mā te tautoko i te mahi a ēnei whākōkī, ka āwhina a AKG ki te whakatika i ngā kino o te DNA me te pupuri i te pumau o te ira.
Pānga ārai mate: Ka taea e te AKG te whakaiti i te kino o te DNA i puta mai i te ahotea waikura mā te whakakore i ngā rauropi kore utu me ngā momo hāora tauhohe (ROS).
He mea nui te ahotea waikura e arahi ana ki te kino o te DNA me te koroheketanga o ngā pūtau. Mā te whakarei ake i te kaha ārai-waikura o ngā pūtau, ka taea e AKG te āwhina ki te aukati i te kino o te DNA e pā ana ki te ahotea waikura.
Te whakatikatika i ngā pūtau me ngā kiko
He mea nui te mahi a te AKG ki te whakatikatika pūtau me te whakaora kiko, mā roto i ēnei ara matua:
Whakatairanga i te mahi a ngā pūtau take: Ka taea e te AKG te whakarei ake i te mahi me te kaha whakaora o ngā pūtau take. E whakaatu ana ngā rangahau ka taea e te AKG te whakaroa i te roa o te ora o ngā pūtau take, te whakatairanga i tō rātou rerekētanga me te tipu haere, ā, ka whai wāhi ki te whakaora me te whakatikatika kiko.
Mā te pupuri i te mahi a ngā pūtau take, ka taea e AKG te whakaroa i te koroheketanga o ngā kiko me te whakapai ake i ngā āheinga whakaora o te tinana.
Whakarei ake i te pākia o te pūtau me te autophagy: Ka whai wāhi a AKG ki te huringa waikawa tricarboxylic (huringa TCA) ā, he hua takawaenga nui o te pākia o te pūngao pūtau.
Mā te whakarei ake i te whai huatanga o te huringa TCA, ka taea e AKG te whakanui ake i ngā taumata pūngao pūtau me te tautoko i te whakatikatika me te tiaki mahi a ngā pūtau.
Hei tāpiritanga, kua kitea te kaha o AKG ki te whakatairanga i te tukanga autophagy, e āwhina ana i ngā pūtau ki te tango i ngā wāhanga kua pakaru, me te pupuri i te hauora o ngā pūtau.
Te taurite ira me te whakahaere epigenetic
He mahi nui tā AKG ki te taurite ira me te whakahaere ira epigenetic, e āwhina ana ki te pupuri i te mahi noa me te hauora o ngā pūtau:
Ka awe i te whakahaere ira epigenetic: Ka whakahaere a AKG i ngā tauira whakaaturanga ira mā te whai wāhi ki ngā whakarerekētanga epigenetic, pērā i te demethylation o te DNA me ngā histones.
Ko te whakahaere ira-ira he tikanga whakahaere matua mō te whakaaturanga ira me te mahi pūtau. Mā te mahi a AKG ka taea te āwhina i te pupuri i te whakaaturanga noa o ngā ira me te ārai i ngā mate me te koroheketanga i puta mai i te whakaaturanga ira rerekē.
Ārai i te urupare mumura: Ka taea e te AKG te whakaiti i te urupare mumura mau tonu e pā ana ki te koroheketanga mā te whakahaere i te whakaaturanga ira.
Ko te mumura mau tonu te pūtake o ngā mate maha e pā ana ki te koroheketanga, ā, ka taea e ngā pānga ārai-mumura o AKG te āwhina ki te aukati me te whakamama i ēnei āhuatanga.
Whakaroa i te koroheketanga me te rongoā i ngā mate pūmau
Nā ngā mahi maha a AKG ka taea e ia te whakaroa i te koroheketanga me te rongoā i ngā mate pūmau:
Te whakaroa i te koroheketanga: Mā te whakatairanga i te whakatikatika i te DNA, te whakarei ake i te kaha ārai mate, te tautoko i te mahi pūtau take, te whakahaere i te whakaaturanga ira, me ētahi atu, ka taea e AKG te whakaroa i te tukanga koroheketanga o ngā pūtau me ngā kiko.
E whakaatu ana ngā rangahau kararehe mā te tāpiri AKG ka taea te whakaroa i te roanga o te oranga me te whakapai ake i te hauora o ngā kararehe kua pakeke.
Te rongoā i ngā mate pūmau: Nā ngā pānga o AKG ki te whakapai ake i te mahi pākia o te tinana, te ārai i te mumura, me te ārai i te mate pūmua, ka whai hua pea i roto i te rongoā i ngā mate pūmau.
Hei tauira, tera pea he pānga ārai me te rongoā a AKG ki te mate huka, ki ngā mate ngakau, ki ngā mate neurodegenerative, me ētahi atu.
Whakarāpopototia
He mahi tā AKG ki te whakaroa i te koroheketanga me te rongoā i ngā mate pūmau mā te whakatika i te DNA, te whakatairanga i te whakatikanga pūtau me te kiko, te pupuri i te taurite ira me te whakahaere i te epigenetics.
Nā te pānga mahi tahi o ēnei tikanga ka waiho a AKG hei ūnga whai hua mō te wawaotanga ārai-pakeketanga me te mate mau tonu.
Ā te heke mai, mā ngā rangahau anō ka kitea ngā painga pea o AKG me ōna āheinga.
