Phekolo phatsa ea lefutso

Gene phekolo - kalafo ena ke lefa bao e seng lefa, mafu multifactorial, eo e phethahatsoa ka ho kenyelletsa phatsa ea lefutso ka mokuli liseleng tse ling. Sepheo sa phekolo ke ho felisa mefokolo liphatsa tsa lefutso kapa hore lisele litšobotsi tse ncha. bonolo haholo ho kena ka seleng e ka bophelo bo botle, ka botlalo ho sebetsa phatsa ea lefutso, ho feta ho lokisa mefokolo ea teng.

Gene phekolo e felle feela lithuto tsa ka lisele somatic. Sena ke ka ntlha ya go ha e le hantle hore ho na le tshitiso efe kapa efe le lisele tsa ho kopanela liphate le embryonic ka fana ka sephetho tsejoa esale pele haholo.

Jwale mokhoa dirisega ke e atlehang ho phekola mafu a bobeli monogenic le multifactorial (lihlahala tse kotsi, mefuta e meng ea mafu a boima la pelo, mafu a bongata ba kokwanahloko).

About 80% ea merero tsohle tse amanang le phekolo phatsa ea lefutso, tšoaetso ea HIV le lefu la kankere. Hona joale, ho etsa lipatlisiso e khannoa joalo mafu a lefa ka hemophilia B, lefu Gaucher e, cystic fibrosis, hypercholesterolemia.

Kalafo ya mafu a liphatsa tsa lefutso e kenyeletsa:

· The kgetho le boikatiso ea mefuta motho ea lisele ka mamello;

· The selelekela tsa liphatsa tsa lefutso tsoang linaheng tse ling;

· The kgetho ya lisele tse eo ho eona "tšoaroa" phatsa ea lefutso tsoang linaheng tse ling;

· Implantation ho mokuli (mohlala, ke tšelo ea mali).

Gene phekolo e thehiloe ho qaloa ho DNA cloned ka lisele tsa mokuli. The mekhoa atlehang ka ho fetisisa a nkoa e le ente injectable le aerosol.

Gene phekolo e sebetsa ka litsela tse peli:

1. Phekolo ya mafu monogenic. Tsena li akarelletsa meferefere ka boko ba hore li amahanngoa le tšenyo e leha e le efe ho lisele tse hlahisang neurotransmitters.

2. Kalafo ea mafu a lefa. The le atamela ka sehloohong o ile a sebelisa ka tsebo:

· Liphatsa tsa lefutso Ntlafatso ea lisele boitshireletso;

· Ho eketsa ya immunoreactivity tsa hlahala ea;

· Block le pontšo ea oncogenes;

· Ho Sireletsa lisele tse phetseng hantle, ho tloha ka chemotherapy;

· Keletso hlahala suppressor liphatsa tsa lefutso;

· The tlhahiso ea mahlahana a khahlanong le hlahala lisele tse phetseng hantle;

· Production ya ente antitumor;

· Local grip ya lisele tse tlwaelehileng ka ho sebedisa antioxidants.

Ho sebelisa phekolo phatsa ea lefutso e na le menyetla e mengata, 'me ka linako tse ling ke feela monyetla oa bophelo bo tloaelehileng bakeng sa batho ba kulang. Leha ho le joalo, sebaka sena sa saense e sa utloisise ka ho feletseng. Ho na le thibelo e machaba ka liteko tsa genital le pele ho implantation lisele tse embryonic. Sena se etsoa e le hore ho thibela agang batleheng phatsa ea lefutso le liphetoho liphatseng tsa lefutso.

Ntshetswa pele a ba a amohela tse ling tsa maemo ao re thulana le liteko tsa tleleniki di dumelletswe:

1. Phatsa ea lefutso ka isoa ka lisele tsa tsona li korotse, e lokela ho ba motho ea mafolofolo bakeng sa nako e telele.

2. The mojaki tikoloho ya phatsa ea lefutso lokela ho lula katleho lona.

3. Gene phetiso ha aa lokela ho etsa hore liphetoho tse bohloko 'meleng.

Ho na le a 'maloa a litokollo tsa tse setseng tsa bohlokoa kajeno le bakeng sa bo-rasaense ba bangata lefatšeng ho pota:

• Tla bo-rasaense ba ho sebetsa tšimong ea phekolo phatsa ea lefutso, ho ntshetsa pele e genokorrektsiyu ka ho feletseng hore o tla se sokela ho litloholo?

• Tla ho hlokahala hore le molemo ea phekolo phatsa ea lefutso phekolo bakeng sa banyalani ba bang ba ho khetheha feta mathateng a tshitsiso ho nakong e tlang moloko oa batho?

• Hore na mekgwatshebetso ya ho joalo li loketse, fuoa overpopulation ea polanete ea nakong e tlang?

• Ba ne ba tla pheta mekgwatshebetso ya ho tšoanang ka batho ba ena le lipotso homeostasis tsa biosphere le sechabeng?

Qetellong, re lokela ho hlokomela hore phekolo liphatsa tsa lefutso ho ba sethaleng joale a moloko oa batho e fana ka litsela tsa ho tšoara mafu a tebileng ka ho fetisisa eo ho fihlela morao tjena ba ne ba nkoa sa phekoleheng 'me a bolaeang. Leha ho le joalo, ka nako e tšoanang, tsoelo-pele ea saense ea ena toba bo-rasaense ba mathata a macha a lokelang ho tobisoa kajeno.
