Te Hangarau Ira i roto i te Koiora: He Huringa i roto i te Rongoā me ngā Pūtaiao Hauora
Ko te hangarau ira, e mōhiotia ana ko te whakarerekētanga ira, ko te tukanga o te whakahaere tika i te DNA o tētahi rauropi hei whakarerekē i ngā āhuatanga motuhake. Kua hurihia e tēnei hangarau ngā momo mara, tae atu ki te ahuwhenua, te ahumahi, me te rongoā koiora. I roto i te horopaki koiora, ka tukuna e te hangarau ira he tumanako hou mō te tautuhi, te maimoatanga, me te aukati i ngā momo mate. Ka matapakihia e tēnei tuhinga ngā tono, ngā painga, me ngā wero e pā ana ki te hangarau ira i roto i te rongoā koiora.
He Hītori Poto o te Hangarau Ira
I rongonui whānuitia te kupu "hangarau ira" i muri i te kitenga o te hanganga o te DNA e James Watson rāua ko Francis Crick i te tau 1953. Heoi, ko te whakamahinga tuatahi o te hangarau ira i roto i te koiora hauora kāore i puta tae noa ki te tau 1973, i te wā i angitu ai a Paul Berg ki te whakauru i te DNA ke ki roto i te huaketo lambda. Ko tētahi atu taahiraa nui ko te whakawhanaketanga o te tikanga CRISPR-Cas9 e Jennifer Doudna rāua ko Emmanuelle Charpentier i te tau 2012, e taea ai te whakatika ira tika ake, whai hua ake hoki.
Ngā Whakamahinga o te Hangarau Ira i roto i te Rongoā Koiora
1. Te Whakaora Ira
Ko te whakaora ira tētahi o ngā tono tino whai hua o te hangarau ira. Kei roto i tēnei tikanga te whakakapi, te muku, te tāpiri rānei i ngā wāhanga o te DNA hei rongoā i ngā mate ira . Ko ngā tauira o ngā mate ka taea te aro atu ki te whakaora ira ko te cystic fibrosis, te hemophilia, me ētahi momo mate pukupuku. Ko te whakamahinga o ngā kawe huaketo, te DNA plasmid, me ngā nanoparticles ētahi o ngā tikanga e whakawhanakehia ana hei tuku i ngā ira kua whakarerekētia ki ngā pūtau e arohia ana.
2. Te Whakaora Ārai Matepukupuku
Kua whakaatuhia te pūmanawa o te rongoā ārai mate ira-ā-ira mō te rongoā mate pukupuku. Ko tēnei tikanga he whakarerekē ira i ngā pūtau ārai mate, pērā i ngā pūtau-T, kia pai ake ai te mōhio me te patu i ngā pūtau mate pukupuku. Ko tētahi tikanga rongonui ko te rongoā CAR-T (chimeric antigen receptor T-cell), e hauhaketia ai ngā pūtau-T o te tūroro, ka whakarerekētia ira, ka whakahokia ki te tinana hei whakaeke i ngā pūtau mate pukupuku.
3. Tātaritanga Ira
Kua whakawāteahia hoki e te hangarau ira te ara mō ngā whakamātautau tātaritanga tere ake, tika ake hoki. E whakamahia ana ngā tikanga pēnei i te CRISPR, te polymerase chain reaction (PCR), me te DNA sequencing hei kimi i ngā whakarerekētanga ira e pā ana ki ngā mate motuhake. Kua noho te tātaritanga ira hei taputapu whai hua mō te kimi me te rongoā wawe i ngā mate ira me ngā mate pāwera , tae atu ki te COVID-19.
4. Te Hanga Rongoā me ngā Kano Kano
Nā te hangarau ira i tere ake ai te whanaketanga o ngā rongoā hou me ngā kano kano . Ko te insulin tangata i hangaia e ngā huakita recombinant tētahi o ngā angitu tuatahi o te hangarau koiora. Nō nā tata nei, kua whakaatuhia e ngā hangarau e hangai ana ki te mRNA, pērā i ngā mea e whakamahia ana i roto i ngā kano kano COVID-19 a Pfizer-BioNTech me Moderna, he tere me te whai huatanga onge i roto i te urupare ki te mate urutā o te ao.
Ngā Hua o te Hangarau Ira i roto i te Rongoā Koiora
1. Maimoatanga Whaiaro
Mā te mārama ake ki te ira o te tangata takitahi, ka taea te whakarite i te maimoatanga kia rite ki ngā hiahia motuhake o ia tūroro. Mā te rongoā whaiaro ka nui ake te whai huatanga, ā, ka whakaiti i te tūponotanga o ngā pānga taha. Ko ngā tikanga pēnei i te raupapatanga ira katoa me te tātaritanga tohu koiora he taputapu e whakamahia ana hei whakatutuki i tēnei taumata whakawhaiaro.
2. Whakateretere i te Rangahau me te Whakawhanake
Mā te hangarau ira ka taea e ngā kaipūtaiao te whakarerekē i ngā tauira rauropi pērā i te kiore me te ika zebra hei ako hohonu ake i ngā mate. Ka taea te hanga i ēnei tauira rauropi hei whakaatu i ngā ira tangata, hei whakaatu rānei i ngā tohu mate motuhake, hei whakatere i te rangahau me te whanaketanga o ngā rongoā.
Mā ngā tikanga pēnei i te tātaritanga ira i mua i te whakatōnga (PGD) ka taea e ngā tāne me ngā wāhine e tino mōrearea ana ki ngā mate ira te whānau tamariki me te kore e pangia e aua mate. Mā te whakamātautau i ngā kukune i whakawhanakehia mā te whakatōnga in vitro (IVF) i mua i te whakatōnga, ka taea te karo i ngā mate ira nui.
Ngā Wero me ngā Tautohenga
Ahakoa ngā painga nui, he maha ngā wero me ngā tautohe e pā ana ki te hangarau ira i roto i te koiora rongoā.
1. Ngā Tikanga Matatika
Ka ara ake ngā raruraru matatika i te whakarerekētanga ira. Ko te pātai mō ngā "pēpi hoahoa" me te whakamahinga pea o te hangarau hei whakarei ake i ngā āhuatanga kore-hauora (pēnei i te teitei, te mohio rānei) he take tautohetohe nui. He mea nui ngā kaupapa here me ngā ture mārama hei whakarite i te whakamahinga whakaaro nui me te matatika o tēnei hangarau.
2. Haumarutanga
Ko te haumaru tētahi atu āwangawanga nui. Kei te whakamātautau tonu te rongoā ira me ētahi atu tikanga whakatika ira, ā, kāore anō kia tino mārama ngā pānga taha, ngā mōrearea rānei mō te wā roa. Ko ngā aituā pēnei i te whakahohenga o ngā ira oncogenic, ngā urupare ārai mate kāore e hiahiatia rānei, he mōrearea pea me aro atu i mua i te whakamahinga whānui o ēnei hangarau.
3. Te Wātea
He maha ngā wā e hiahiatia ana he hangarau matatau me ngā utu nui mō te hangarau ira, ā, kāore e taea e te katoa te uru atu. Kei te āwangawangahia kei te whai hua anake tēnei hangarau ki te hunga e taea te utu, ā, ka waiho te hunga rawakore ki muri. Ko te pumau me te ōritetanga o te urunga atu he wero me aro atu e te hapori o te ao.
Te Anamata o te Hangarau Ira i roto i te Rongoā Koiora
He nui ngā pūmanawa kei te heke mai o te hangarau ira i roto i te koiora. Kei te haere tonu te whanaketanga o ngā hangarau pēnei i te CRISPR me te rongoā ira, ā, kei te kitea tonutia ngā tono hou. I ngā tekau tau e haere ake nei, tera pea ka kite tātou i tētahi huringa nui i roto i te huarahi e tātaritanga ai, e rongoā ai, e ārai ai hoki i te mate.
Heoi, kia tutuki ai te pūmanawa katoa o tēnei hangarau, he mea nui te mahi tahi a ngā kaipūtaiao, te ahumahi, ngā kāwanatanga, me te marea whānui. Hei tāpiri, me whai ture pakari me te rangahau tonu kia mau ai te haumaru me te whai huatanga o ngā tono hangarau ira i roto i te koiora rongoā.
Whakamutunga
Mā te hangarau ira i roto i te rongoā koiora ka tukuna he tumanako hou me ngā otinga auaha ki te whānuitanga o ngā wero hauora. Mai i te whakaora ira ki te whakaora ārai mate pukupuku, kei tēnei hangarau te kaha ki te whakarerekē i te huarahi e whakaaro ai tātou ki te rongoā me te tiaki hauora. Heoi, me ēnei kaha katoa ka tae mai te kawenga nui ki te aro atu ki ngā wero matatika, haumaru, me te urunga atu. Mā te huarahi tupato me te mahi tahi, ka taea e te hangarau ira te noho hei kī ki tētahi heke mai pai ake me te tika ake mō te katoa.
