Yog zawv plaub hau thiab da dej tshuaj kua yuav ua rau mob cancer?

Nyob rau hauv cov phau ntawv journal Cell luam tawm ib tsab xov xwm tus zaum uas nyuam qhuav ua ib tug tshiab txoj kev tshawv. Daim ntawv tshwm sim los ib do nyob rau hauv cov xov xwm, thiab lawv pib tham txog qhov tseeb hais tias txhua txhua hnub "Science News for KIDS" uas peb siv, yuav ua rau mob cancer. Obviously, xws li ib tug xov tsum noj nrog ib tug pinch ntawm sarcasm, thiab ua ntej ua tej cov lus xaus, paub raws nraim li cas hais txoj kev tshawb no sau phau ntawv.

tej yam tshuaj lom

Nws twb muaj nyob rau hauv cov kev taw qhia ntawm zaum los ntawm Cambridge University, uas kawm txog tej yam rau cov neeg kho mob yuav muaj xws li ib tug hauv chav kawm ntawv ntawm cov tshuaj raws li aldehydes. Muaj ntau fragrances yog aldehydes, thiab lawv feem ntau muaj nyob rau hauv tso gases ntawm tsheb ntawm khoom siv da dej, hluav taws xob luam yeeb thiab lub tsev ntaub ntawv.

Zaum hais tias ib txhia aldehydes yuav cuam tshuam nrog cellular kho mechanisms, ces lawv txiav txim siab los yamntxwv lawv tej zaum carcinogenic nyhuv. Cov pab neeg teem rau formaldehyde thiab acetaldehyde.

Siv ib tug ntau yam ntawm cov poj niam txoj kev mob hlwb muab ncu nyob rau hauv cov tshuaj, pab neeg no piv rau DNA tam sim no nyob rau hauv lawv, ua ntej thiab tom qab raug tus kab mob. Kev mloog yog them rau ib tug noob hu ua BRCA2, vim hais tias yav dhau los cov kev tshawb fawb pom tau hais tias tej kev yuam cai ntawm nws leads mus rau ib tug muaj zog rhiab heev rau tej chemical tshuaj lom thiab kev hloov nyob rau hauv chromosome qauv.

Tseeb, ob lub aldehyde coj mus rau BRCA2 kev puas tsuaj. Yog hais tias ib tug neeg tsuas muaj ib tug ua hauj lwm daim ntawv ntawm cov noob, nws puas yuav ua rau tsis ua hauj lwm ntawm tus yuam sij protein rov qab mechanism, uas muaj peev xwm muaj feem ua rau mob cancer. Uas yog vim li cas rau hauv xov xwm tau muab daim ntawv qhia mus rau hauv ib tug nov ntawm nqaij tawv thiab pib paub tias muaj ntau yam ntawm cov aldehydes muaj nyob rau hauv cov khoom noj, tej zaum yuav ua rau kom txoj kev pheej hmoo ntawm mob cancer.

Ntsiab lus

Txawm li cas los, lawv tsis muaj ib tug ob peb tseem ceeb. Firstly, txoj kev pheej hmoo ntawm mob cancer vim cov kev siv ntawm tsuaj zawv plaub hau los yog nqus me me ntawm vapor los ntawm cov hluav taws xob luam yeeb yog tsawg heev. Secondly, feem ntau ntawm cov aldehydes tsis yog kev ua dag cov khoom, tab sis kuj nyob rau hauv lub cheeb tsam.

Soj ntsuam kuj tsis rau npe rau tej tshuaj lom ntau ntawm cov aldehydes, yog li ntawd nws tsis yog tseeb yuav ua li cas muaj ntau yam yuav muaj kev nyab xeeb uas tej zaum yuav ua rau tiag tiag kev puas tsuaj. Tsis yog txhua txhua tus neeg yog raug rau kev hloov ntawm cov noob BRCA2, thiab tseem tsis to taub yog vim li cas.

Tsis zaum tau ua yuam kev?

Qhov no tsis tau txhais hais tias ua yuam kev raug ua nyob rau hauv txoj kev tshawb no. Qhov teeb meem no yog hais tias qhov kev tshwm sim tau distorted los ntawm cov xov xwm. Txoj kev tshawb no ua tau muab peb ib tug me me lub tswv yim ntawm yuav ua li cas ib qho tseem ceeb nws yog los kawm txog cov kev pheej hmoo ntawm kev siv aldehydes. Txawm li cas los, nws tsis yog lawm hais tias kev siv ntawm tsuaj zawv plaub hau los yog da dej gel, piv txwv li, yog ib tug loj ua rau mob cancer nyob rau hauv tib neeg. Soj ntsuam ntawm tsuas yog siv lom qauv qhia li cas txog cov tshuaj hu ua aldehydes, yuav ua rau mob cancer.
