Bioinformatics
1.LncRNA kev faib tawm
LncRNA kwv yees los ntawm plaub softwares saum toj no tau muab faib ua 4 pawg: lincRNA, anti-sense-LncRNA, intronic-LncRNA;kev-LncRNA.LncRNA kev faib tawm tau pom nyob rau hauv histogram hauv qab no.

2.Cis-targeted genes ntawm DE-lncRNA enrichment tsom xam
ClusterProfiler tau ua haujlwm nyob rau hauv GO enrichment tsom xam ntawm cis-targeted noob ntawm txawv qhia lncRNA (DE-lncRNA), hais txog cov txheej txheem lom neeg, molecular zog thiab cellular Cheebtsam.GO enrichment tsom xam yog txheej txheem los txheeb xyuas DEG-qhia kom muaj txiaj ntsig GO cov ntsiab lus piv rau tag nrho cov genome.Cov ntsiab lus enriched tau nthuav tawm hauv histogram, daim duab npuas, thiab lwm yam raws li qhia hauv qab no.

3. Los ntawm kev sib piv qhov ntev, tus lej exon, ORF thiab kev nthuav qhia tus nqi ntawm mRNA thiab lncRNA, peb tuaj yeem nkag siab qhov sib txawv ntawm cov qauv, ntu thiab lwm yam ntawm lawv, thiab tseem xyuas seb qhov tshiab lncRNA kwv yees los ntawm peb ua raws li cov yam ntxwv dav dav.

Qauv sau
Lub NONMMUT015812-knockdown KP (shRNA-2) hlwb thiab kev tswj tsis zoo (sh-Scr) hlwb tau txais nyob rau hnub 6 ntawm tus kab mob tshwj xeeb.
Cov txiaj ntsig tseem ceeb
Txoj kev tshawb no tshawb xyuas qhov tsis zoo ntawm lncRNAs hauv nas ntsws adenocarcinoma nrog P53 knockout thiab KrasG12D kev hloov pauv.
1.6424 lncRNAs tau qhia txawv txawv (≥ 2-fold hloov, P <0.05).
2.Ntawm tag nrho 210 lncRNAs (FC≥8), 11 lncRNAs 'kev qhia tau tswj hwm los ntawm P53, 33 lncRNAs los ntawm KRAS thiab 13 lncRNAs los ntawm hypoxia hauv thawj KP hlwb, feem.
3.NONMMUT015812, uas tau zoo kawg li tswj hwm hauv nas ntsws adenocarcinoma thiab tswj tsis zoo los ntawm P53 rov qhia dua, tau tshawb pom los tshuaj xyuas nws txoj haujlwm ntawm tes.
4.Knockdown ntawm NONMMUT015812 los ntawm shRNAs txo qis proliferation thiab migration peev xwm ntawm KP hlwb.NONMMUT015812 yog qhov muaj peev xwm oncogene.
