Ma telomere komanso kufupika kwake kumayambitsa shuga
Ma Micrograph a ma chromosome a anthu okhala ndi ma telomeres (omwe akuwonetsedwa mwa pinki). (Chithunzi: Mary Armanios)
Ma Telomeres akubwereza mndandanda wa DNA womwe umateteza ku malekezero a ma chromosomes. Thupi likamakula, nthawi zambiri limafupika. Zikatero, maselo amalephera kugawa mwachizolowezi, ndipo pamapeto, amafa. Kufupikitsa kwa Telomere kumalumikizidwa ndi khansa, matenda am'mapapo, ndi matenda ena okalamba. Matenda a shuga, omwe amaphatikizidwanso ndi ukalamba, amakhudza munthu mmodzi mwa akulu anayi woposa zaka 60.
Kafukufuku wa asayansi ku yunivesite ya Johns Hopkins, omwe adasindikizidwa mu magazini ya PloS One, adakhazikika pa zomwe a Mary Armanios, omwe adaganizira za kukhalapo kwa ubale weniweni pakati pa zochitika za matenda ashuga komanso dyskeratosis (dyskeratosis congenital), matenda achilendo obadwa nawo chifukwa chophwanya njira yokonza kutalika kwa telomere. Odwala omwe ali ndi cholowa chokhala ndi dyskeratosis, kusakhazikika kwa msanga ndi kulephera koyambirira kwa ziwalo zambiri nthawi zambiri kumawonedwa.
“Congenital diskeratosis ndi matenda omwe amachititsa kuti anthu azikalamba asanabadwe. Tinkadziwa kuti kuchuluka kwa anthu odwala matenda ashuga kumawonjezeka ndi ukalamba, choncho tidayesetsa kuti pakhale kulumikizananso pakati pa ma telomeres ndi matenda ashuga, "anatero kafukufuku Armanios, pulofesa wothandizira pa onology pa Kimmel Cancer Center, University of Johns Hopkins.
Odwala omwe ali ndi matenda ashuga, osapatsidwa insulin yokwanira, ndipo maselo awo sangathe kuwagwiritsa ntchito moyenera, zomwe zimayambitsa kuphwanya malamulo a shuga.
Armanios adaphunzira mbewa zazifupi ndi ma telomeres achidule komanso maselo ake opanga insulin. Adapeza kuti ngakhale panali ma cell a beta ambiri owoneka bwino, kuchuluka kwa shuga m'magazi amenewa kunali kokulirapo, ndipo maselo amatulutsa insulin iwiri kuposa nyama za gulu lotsogolera.
"Izi zikufanana ndi magawo oyambirira a matenda ashuga mwa anthu, pamene maselo amavutika kutulutsa insulin chifukwa cha shuga," akufotokoza Armanios. "Ndi mbewa zoterezi m'malo ambiri obisika insulin"Kuchokera pakupanga mphamvu pogwiritsa ntchito mitochondria mpaka calcium, maselo amagwira ntchito pang'ono," anatero Armanios.
M'maselo a beta a mbewa zokhala ndi ma telomeres achidule, asayansi apeza kuthekera kwa mtundu wa p16 wogwirizana ndi ukalamba ndi matenda ashuga. Kuphatikiza apo, mitundu yambiri yamayendedwe ofunikira kuti insulin itulutsidwe, kuphatikizapo njira yomwe imayang'anira kuwonetsera kwa calcium, idasinthidwa mwa iwo. Gulu lolamulira, palibe zolakwika zotere zomwe zidapezeka.
Kafukufuku wam'mbuyomu adawonetsa kuti odwala matenda ashuga amatha kukhala ndi ma telomeres achidule, koma kodi amawonjezeka chiwopsezo cha matenda a shuga kapena chotsatira cha matendawa, sichikudziwika bwinobwino.
“Ukalamba ndi chiopsezo chachikulu cha matenda ashuga. Kuphatikiza apo, cholowa m'mabanja chimagwira ntchito yofunika kwambiri. Kutalika kwa ma telomeres ndi gawo lobadwa nawo ndipo kungapangitse anthu kuyamba kukonda matenda ashuga, "akukhulupirira Armanios.
Kutengera ndi ntchitoyi, Armanios akutsimikiza kuti kutalika kwa telomere kumatha kugwira ntchito yopanga chitukuko matenda ashuga. Kafukufuku wowonjezereka, asayansi akukonzekera kuti adziwe ngati zingatheke kuneneratu kuopsa kwa matendawa kutengera kutalika kwa telomere. "
Ma telomere komanso kufupika kwake kumayambitsa shuga
Ma telomere komanso kufupika kwake kumayambitsa shuga
Kodi ndichifukwa chiyani anthu omwe amakhala ndi mafuta ambiri am'mimba amawonjezera kukana kwa insulin komanso kuthekera kwa matenda ashuga? Zakudya zopanda pake, moyo wongokhala ndi kupsinjika kumathandizira kuti pakhale mafuta am'mimba komanso kuwonjezeka kwa shuga m'magazi. Mwa anthu omwe ali ndi m'mimba, ma telomere amakhala amafupikitsa zaka <5>, ndipo zikuwoneka kuti kuchepa kwawo kumakulitsa vutoli chifukwa cha kukana insulini. Pakufufuza kwa ku Denmark komwe mapasa 338 adatenga nawo gawo, zidapezeka kuti ma telomeres achidule ndi omwe amayambitsa kukana insulini pazaka 12 zotsatira. M'mapasa awiri aliwonse, m'modzi mwa iwo omwe ma telomeres awo anali afupifupi adawonetsa kukana kwambiri kwa insulin <6>.
Asayansi awonetsa mobwerezabwereza mgwirizano pakati pa telomeres lalifupi ndi matenda ashuga. Ma telomeres achidule amawonjezera mwayi wokhala ndi matenda ashuga: anthu omwe ali ndi cholowa chaifupi telomere syndrome ali ndi mwayi wokhala ndi matendawa kuposa anthu ena onse. Matenda a shuga amayambira molawirira ndipo amakula mwachangu. Kafukufuku wa amwenye, omwe pazifukwa zingapo ali pachiwopsezo chachikulu cha matenda ashuga, amaperekanso zokhumudwitsa. Ku India wokhala ndi ma telomeres achidule, mwayi wokhala ndi matenda ashuga mzaka zisanu zikubweranso kawiri kuposa nthumwi za mtundu womwewo wokhala ndi ma telomeres <7>. Kuwunika kwa meta komwe kunakhudza anthu opitilira 7,000 kunawonetsa kuti ma telomeres amfupi m'magazi amawu ndi chizindikiro chodalirika cha matenda am'tsogolo a shuga [8].
Sitikudziwa njira yopanga matenda a shuga, komanso titha kuyang'anitsitsa mu kapamba kuti tiwone zomwe zimachitika mmenemo. Mary Armanios ndi anzawo adawonetsa kuti mbewa, ma telomere atachepetsedwa mthupi lonse (asayansi adakwaniritsa izi ndi kusintha kwa majini), maselo a pancreatic beta amataya kutulutsa insulin <9>. Ma cell a stem mu kanyumba akalamba, ma telomeres awo akuchepera kwambiri, ndipo salinso kubwezeretsanso kuchuluka kwa maselo a beta omwe ali ndi udindo wopanga insulin komanso kuwongolera msinkhu wake. Maselo awa amafa. Ndipo ndikulemba kuti matenda ashuga amayamba bizinesi. Ndi mtundu wachiwiri wa matenda ashuga II, maselo a beta samafa, koma magwiridwe akewo ndi operewera. Chifukwa chake, pankhaniyi, nawonso, mawu achidule am'mimba kapamba angatenge gawo.
Mwa munthu wina wathanzi, mlatho kuchokera pamimba kumimba mpaka matenda a shuga ungayikidwe ndi bwenzi lathu lakale - kutupa kosatha. Mafuta am'mimba amathandizira kwambiri kukulitsa kutupa kuposa, titero, mafuta m'chiuno. Maselo amtundu wa Adipose amapanga zinthu zomwe zimapangitsa kuti maselo aziteteza chitetezo chamthupi, zisanafike pang'onopang'ono, zimapangitsa kuti ziwonongeke komanso kuwononga telomeres. Monga momwe mukukumbukira, maselo akale, nawonso, amavomerezedwa kuti atumize zizindikiro zosayimira zomwe zimalimbikitsa kutupa mthupi lonse - bwalo loipa limapezeka.
Ngati muli ndi mafuta ochulukirapo am'mimba, muyenera kusamala kuti mudziteteze ku kutupa kosatha, telomeres yochepa, ndi metabolic syndrome. Koma musanadye chakudya kuti muchotse mafuta am'mimba, werengani chaputala ichi mpaka kumapeto: mutha kusankha kuti kadyedwe kamangokulira. Osadandaula: tikukupatsani njira zinanso zotithandizira kuti kagayidwe kanu kagwire.

Panalibe kusiyana kulikonse pamlingo wa MDA pakati pa magulu a T2DM + ndi T2DM (mwina chifukwa cha nthawi yochepa ya matenda ashuga komanso kusakhalapo kwa hyperglycemia yayitali, popeza hyperglycemia yotalika nthawi yayitali imalumikizidwa ndi kukhazikika kwa kupsinjika kwa oxidative koopsa. Pangakhale kofunikira kugwiritsa ntchito zowonetsera zowonjezereka za kupsinjika kwa oxidative, monga kwamikodzo excretion ya 8-iso-prostaglandin F2a. Tidapeza ziwonetsero zambiri za odwala omwe ali ndi matenda a shuga 2 kuposa omwe ali m'gululi. Chizindikiro china chotupa, IL-6, monga momwe chidawululidwira posachedwa, chimakhala ndi zotsatira zingapo, sichokhala cytokine yokha, komanso myokine, yolimbikitsa myogeneis komanso zimapindulira moyenera metabolism. Mwina ndichifukwa chake mulingo wa IL-6 muulamulirowo unakhala wokwera kwambiri, womwe, komabe, umafunanso kuphunzira kwina.
Kutupa kosatha kumayambitsa kukalamba kwa maselo, telomere kufupikitsa ndikuwonjezera kuchuluka kwa maselo a lymphocytic ndikuyambitsa kutulutsidwa kwa ROS, ndikupangitsa kuwonongeka kwa oxidative ku gawo la DNA. Mu 2012, zidawonetsedwa kuti kufupika kwapang'onopang'ono kwa ma telomeres okhala ndi kuwonjezereka kwa nthawi ya T2DM kungaphatikizidwe ndi kuwonjezereka kofanana kwa kupsinjika kwa oxidative ndi kutupa kosatha. Zotsatira zathu ndizogwirizana ndi kafukufuku wakale. Tidapeza milingo yayikulu kwambiri ya CRP komanso miyezo yapamwamba kwambiri ya MDA mwa odwala omwe ali ndi matenda ashuga a 2 komanso ma telomeres achidule kuposa odwala omwe ali ndi ma telomeres atali. Panali ubale wopanda pake pakati pa kutalika kwa lymphocyte telomere ndi chikhazikitso chapakatikati cha matenda osachiritsika - CRP, zomwe zikuwonetsa kutengapo gawo pakukhumudwa kwapang'onopang'ono kwa telomere kufupikitsa kwa odwala omwe ali ndi matenda a shuga a 2. Mu gulu loyendetsa, panalibe ubale pakati pa CRP ndi telomere kutalika, komwe kumagwirizana ndi maphunziro ena. Kulephera kuyankhulana pakati pa IL-6, fibrinogen, ndi kutalika kwa telomere m'magulu onsewa kumatha kufotokozedwa ndi kusinthasintha kochepa kwa zizindikirozi. Komanso, kungodalira kuchuluka kwa ma cytokines ozungulira, munthu akhoza kuchepetsa mphamvu ya kutukusira kwanuko m'thupi.
Zomwe mabuku amafotokoza pa ubale wa kutupa kosatha ndi ntchito ya telomerase ndizotsutsana. Kutalika kwa nthawi yayitali kumabweretsa kufooka kwa telomerase, yomwe tidawona odwala omwe ali ndi matenda a shuga 2. Ndi kutupa kocheperako komanso kwanthawi yayitali, monga momwe zimakhalira ndi metabolic syndrome kapena atherosulinosis, m'malo mwake, pali kuwonjezeka kwa zochitika za telomerase, zomwe mwina ndizobwezerera mwachilengedwe, ndikuchepetsa kuchepa kwa kutalika kwa telomere m'magawo
motsogozedwa ndi cytokines yotupa. Zowonadi, gulu loyang'aniranali, tidapeza ubale wabwino pakati pa zochitika za telomerase ndi chizindikiro cha kutupa kosatha.
Ndikofunikira kutsindika kuti, malinga ndi kuchuluka kwa deta yathu, kuchuluka kwa kuphatikiza kwa oxidative, kutupa kwakanthawi ndi zochitika za telomerase kwa odwala omwe ali ndi T2DM ndi ma telomeres a "yayitali" sizinasiyane kwambiri ndi ma indices omwe amagwirizana. Titha kuganiziranso kuti kutalika kwa T2DM, kutalika kwa nthawi yayitali kuteteza odwala ku zowonongeka za kupsinjika kwa oxidative komanso kutupa kwakatundu, kupereka kubwezeretsa bwino komanso kufulumira kwa ziwalo zowonongeka, kuphatikizapo mitsempha yamagazi. Mosiyana ndi izi, odwala omwe ali ndi T2DM komanso ma "telome" afupikitsa, ngakhale atatenga nthawi yochepa matendawa, kuwopsa kwa kutupa kosatha komanso kuchepa kwa ntchito ya telomerase kunali kofunika kwambiri. Tiyenera kudziwa kuti odwala matenda amtundu wachiwiri wa shuga ndi kuwongolera anali ofanana ndi msinkhu.
Pali umboni womwe ukukula kuti kufupikitsa kwa telomere ndichinthu chofunikira kwambiri pakuchepetsa malo osungirako masentimita ndikuwonongeka kwa minyewa yokhudzana ndi zaka. Kuyanjana kwa T2DM ndimayendedwe a kukalamba kwa maselo komanso kuopsa kwa kutupa kwakanthawi ndi kupsinjika kwa oxidative kungathe kufotokozera kuchuluka kwa CVD pamatendawa. Maphunziro owonjezerawa amalola kuganizira kutalika kwa telomere pakati pa odwala omwe ali ndi matenda a shuga a 2, gulu la anthu omwe amafunikira kwambiri kagayidwe kazakudya, komwe kangapereke njira yochiritsira matendawa.
1. Odwala omwe ali ndi matenda a shuga a 2, kutalika kwa telomere kumakhala kufupikitsa, ndipo ntchito ya telomerase ndiyotsika kuposa mwa anthu athanzi. Makhalidwe azomwe amapanga thupi posintha kutalika kwa ma telomeres sanawululidwe.
2. Mulingo wa MDA kwa odwala omwe ali ndi matenda ashuga a 2 komanso anthu athanzi ali ofanana. Matenda opatsirana amatchulidwa kwambiri kwa odwala omwe ali ndi matenda amtundu wa 2 kuposa anthu athanzi lofanana. Kutupa kosafunikira kumakhala ndi gawo lalikulu pakufupikitsa telomeres ndikuwonjezera ntchito ya telomerase.
3. Odwala omwe ali ndi T2DM ndi ma telomeres atali, kuleza kwa kupsinjika kwa oxidative komanso kutupa kosasintha sikumasiyana ndi magawo omwe amagwirizana ndi anthu athanzi
4. Kwa odwala omwe ali ndi T2DM, ma telomeres "achidule" amagwirizanitsidwa ndi kuyendetsa bwino matenda a shuga komanso kupweteka kwambiri pakhungu.
5. Ma telomeres amtundu wautali amateteza odwala omwe ali ndi matenda ashuga pazowonongeka za oxidative nkhawa komanso kutupa kosalekeza.
Palibe kusamvana kwa chidwi.
Kafukufukuyu adachitika ngati gawo la ntchito ya Boma "Kafukufuku wopanga ma atulossiasis kuti apange njira zodziwitsira matenda a atherosclerosis oyambira ngati njira yofunika kwambiri yopangira matenda amtima ndi zovuta zawo."
