Dab tsi yog cell-penetrating peptides?

Cell-penetrating peptides yog cov peptides me me uas tuaj yeem nkag mus rau hauv cov cell membrane yooj yim.Cov chav kawm ntawm cov molecules no, tshwj xeeb tshaj yog CPPs nrog lub hom phiaj ua haujlwm, tuav cov lus cog tseg rau kev xa tshuaj zoo rau cov hlwb.

Yog li ntawd, kev tshawb fawb ntawm nws muaj qee qhov tseem ceeb ntawm biomedical.Nyob rau hauv txoj kev tshawb no, CPPs nrog txawv transmembrane kev ua ub no tau kawm nyob rau theem ib theem zuj zus, sim nrhiav kom paub cov yam uas cuam tshuam rau cov transmembrane kev ua ntawm CPPs, qhov sib txawv ntawm CPPs nrog ntau yam kev ua ub no thiab NonCPPs, thiab qhia ib txoj hauv kev los tshuaj xyuas cov kab mob lom.

CPPs thiab NonCPPs sequences tau txais los ntawm CPPsite database thiab cov ntaub ntawv sib txawv, thiab transmembrane peptides (HCPPs, MCPPs, LCPPs) nrog siab, nruab nrab, thiab qis transmembrane kev ua tau muab rho tawm los ntawm CPPs sequences los tsim cov ntaub ntawv teev.Raws li cov ntaub ntawv no, cov kev tshawb fawb hauv qab no tau ua:

1, Cov amino acid thiab cov qauv theem nrab muaj pes tsawg leeg ntawm txawv CPPs thiab NonCPPs tau soj ntsuam los ntawm ANOVA.Nws tau pom tias kev sib cuam tshuam ntawm electrostatic thiab hydrophobic ntawm cov amino acids ua lub luag haujlwm tseem ceeb hauv kev ua haujlwm ntawm transmembrane ntawm CPPs, thiab cov qauv helical thiab random coiling kuj cuam tshuam rau kev ua haujlwm transmembrane ntawm CPPs.

2. Cov khoom ntawm lub cev thiab tshuaj lom neeg thiab qhov ntev ntawm CPPs nrog cov dej num sib txawv tau tshwm sim rau ntawm lub dav hlau ob sab.Nws tau pom tias CPPs thiab NonCPPs nrog cov dej num sib txawv tuaj yeem ua ke raws li qee qhov tshwj xeeb, thiab HCPPs, MCPPs, LCPPs thiab NonCPPs tau muab faib ua peb pawg, qhia lawv qhov sib txawv;

3. Nyob rau hauv daim ntawv no, lub tswv yim ntawm lub cev thiab tshuaj centroid ntawm biological sequence yog qhia, thiab cov residues composing lub sequence yog suav hais tias yog particle cov ntsiab lus, thiab cov kab lus yog abstracted raws li ib tug particle system rau kev tshawb fawb.Txoj kev no tau siv rau kev soj ntsuam ntawm CPPs los ntawm kev npaj CPPs nrog cov dej num sib txawv mus rau lub dav hlau 3D los ntawm PCA txoj kev, thiab nws tau pom tias feem ntau CPPs pawg ua ke thiab qee qhov LCPPs pawg ua ke nrog NonCPPs.

Txoj kev tshawb no muaj qhov cuam tshuam rau kev tsim CPPs thiab nkag siab txog qhov sib txawv ntawm cov kab ke ntawm CPPs nrog cov haujlwm sib txawv.Tsis tas li ntawd, txoj kev tsom xam ntawm lub cev thiab tshuaj centroid ntawm cov kab mob lom neeg tau qhia hauv daim ntawv no kuj tseem siv tau rau kev txheeb xyuas lwm yam teeb meem lom neeg.Nyob rau tib lub sijhawm, lawv tuaj yeem siv los ua cov khoom nkag rau qee qhov teeb meem kev faib khoom lom neeg thiab ua lub luag haujlwm hauv kev paub txog cov qauv.
