Phuputso e Hlakileng e Senola Tsela e Ncha ea Mala le Sebete bakeng sa Litlamorao tsa Quercetin tsa ho Loantša Botenya
Bafuputsi ba tsoang Univesithing ea Zhejiang ba sibolotse mokhoa o rarahaneng oa ho fetisa matšoao a mala le sebete oo ka oona quercetin, flavonoid ea lijo, e loantša botenya. E phatlalalitsoe ho Saense e Tsoetseng Pele (La 31 Pherekhong 2025), phuputso e hlwaya Akkermansia muciniphilalibaktheria le asiti ea bile Metabolism e le babuelli ba bohlokoa baquercetinlitlamorao tsa ho fokotsa mafura, tse fanang ka tse nchaSontahalipheo tse matla bakeng sa mathata a metabolism.
Semelo sa Lipatlisiso
Botenya le mafu a amanang le metabolism li baka liphephetso tsa bophelo bo botle lefatšeng ka bophara, li susumetsa thahasello lits'ebetsong tsa tlhaho tse kang quercetinHo sa tsotellehe katleho ea eona e tsebahalang, mokhoa o nepahetseng oa ho hokahanya Quercetin Ho lokisa microbiota mala le taolo ya metabolism ha ho a ka ha hlahlojwa. Phuputso ena e koala sekgeo sena ka ho batlisisa hore na quercetin e bopa botjha tikoloho ya dikokwana-hloko jwang ho thibela ho bokellana ha mafura.
Liphihlelo tsa Bohlokoa
-
Lintlafatso tsa Metabolic:
Quercetin tlatsetso lijong tse nang le mafura a mangata (HFD):- Boima ba 'mele bo fokotsehileng le mafura a mangata
- Ho hanyetsa insulin le dyslipidemia ho fokotsehile
-
Nchafatso ea Mala a Microbiota:
Ho latellana ha 16S rRNA ho senotse quercetin:- E ntlafalitsoe Akkermansia muciniphila bongata (keketseho e fetang makhetlo a mararo)
- Mefuta-futa ea likokoana-hloko e senyehileng ka HFD e tsosolositsoeng
-
Letšoao la Metabolite ea Microbial:
A. muciniphila e hlahisitse indole-3-lactic acid (ILA), e leng:- E kentse tshebetsong tsela ya ho tlosa methylation ya m6A e tsamaiswang ke FTO
- Ho eketseha ha tlhahiso ea CYP8B1 sebeteng (enzyme ea bohlokoa bakeng sa ho hlophisoa ha bile acid)
-
Taolo ea Lipid e Fetotsoeng ke Asiti ea Bile:
CYP8B1-driven cholic acid (CA) synthesis e sebetsang mafura a tissue Farnesoid X Receptor (FXR), e fellang ka:- E hatelitsoe hape lipogenesis (SREBP1c↓, FAS↓)
- Ho ntjhafatswa ha oli e tswang mmeleng (PPARα↑)
Netefatso ea Mekaniki
- Litoeba tse se nang likokoana-hloko e jetsoe ka A. muciniphila litlamorao tse iphetotseng tsa quercetin khahlanong le botenya.
- Tsamaiso ea ILA ho fokotseha ha pokello ea lipid ka ho sebelisa FTO/m6A/CYP8B1 signaling.
- FXR knockout e felisitse melemo ea ho fokotsa mafura a quercetin, e leng se tiisang tlhokahalo ea tsela.
Bohlokoa le Litlamorao
"Mosebetsi ona o theha quercetin–Ntlo ea polasi–Sehlopha sa ILA/CA/FXR e le molaoli ea ka sehloohong oa metabolism ea mafura," ho bolela mongoli ea tsamaellanang le eena Moprofesa Xinxia Wang. "Ho shebana le potoloho ena ea mala le sebete ho fana ka leano le lecha la kalafo ea botenya ho feta mekhoa e tloaelehileng." Liphuputso li totobatsa phetoho ea microbiome e le tsela e sebetsang bakeng sa nts'etsopele ea lihlahisoa tsa tlhaho.
