Chitsauko Chekutanga: Kubvisa Cognition: Iyo Anti-Cancer Awakening yeSweet Molecules

1.1 Paradigm Shift muCarbohydrate research

Mupfungwa dzechinyakare, shuga (makabhohaidhiretsi) yagara ichionekwa se "mari yesimba". Kunyanya glucose, seyakakosha substrate yekufema kweserura, kushamwaridzana pakati pekusagadzikana kwemetabolism uye kukura kwegomarara kwakaratidzwa zvizere. Nekudaro, ongororo yakaitwa yakaburitswa neCancer Research UK mujenari Nature muna 2018 yakanyatso nyora rondedzero iyi - timu yekutsvagisa yakasimbisa kekutanga kuti mannose inogona kumisa kupararira kwemaseru egomarara nekukanganisa nzira yebundu yeshuga metabolism, isina mhedzisiro pamatishu akajairwa. Kuwanikwa uku hakungopidigura fungidziro yekuti "shuga dzese dzinokurudzira gomarara", asi zvakare kunovhura nhandare yehondo yekupindira kwemetabolism.

1.2 Biological Traceability yeMannose

Sezvo isomero yeglucose, mannose inogoverwa munzvimbo yakasununguka pane epidermis yemichero yakadai secitrus nemaapuro mumasikirwo, kana kuti inobatanidzwa mukuvakwa kwebiological membranes nenzira ye glycoproteins. Mumuviri wemunhu, mannose inonzi phosphorylated kuumba mannose-6-phosphate (M6P), inova yakakosha kusaina molecule ye lysosomal enzyme kuronga. Kare zvidzidzo zvekiriniki zvakaratidza maitiro ayo mukudzivirira zvirwere zveurinary tract: kuburikidza nemakwikwi kusunga kune adhesion receptors ye pathogenic bacteria, inovharira colonization yavo paurothelium. Hunhu uhu hwakaita kuti pave nemhando dzakasiyana-siyana dzezvekudya zvakanangana nemannose, asi kuwanikwa kweiyo anti-cancer kugona kwakakonzera kuwedzera kweexponential mukushanda kwayo kukosha.

Chitsauko Chechipiri: Scientific Decoding: The Triple Offensive yeMannose Against Cancer

2.1 Metabolic Hijacking: Kucheka "kupindwa muropa neshuga" ketani yekugovera kenza maseru.

Iyo Warburg mhedzisiro yemamota maseru (ayo achiri kuvimba neglycolysis yesimba kunyangwe munzvimbo ine okisijeni-yakapfuma) inogonesa kutora kwavo shuga kuti isvike zvakapetwa kagumi kune maseru akajairwa. Chikwata cheBritish chakawana kuburikidza neisotope yekutsvaga tekinoroji kuti mushure mekunge mannose yapinda maseru egomarara, inogadziriswa nehexokinase kuumba M6P uye inoungana muhuwandu mukati memasero. Iyi "pseudo-metabolite" haingotori chete migero yeglucose transporter (GLUT), asi zvakare inokwikwidza kuvharidzira kuita kwephosphoglucose isomerase, zvichikonzera kusavapo kweakakosha epakati mu glycolysis uye tricarboxylic acid kutenderera, pakupedzisira kukonzeresa dambudziko remagetsi mumasero ekenza (Mufananidzo 1).

2.2 Epigenetics: Kugadzirisazve bundu microenvironment

Ongororo yakaburitswa neFudan University muCell Metabolism muna 2023 yakaratidza zvakare kuti mannose inogona kudzoreredza epigenetic aberrations mumasero egomarara nekudzora mazinga ehistone acetylation. Ongororo dzakaratidza kuti mupancreatic cancer maseru anobatwa nemannose, iyo acetylation dhigirii yedunhu rekusimudzira yeoncogene MYC yakaderedzwa, uye basa rayo rekunyora rinodzivirirwa zvakanyanya. Iyi epigenetic reprogramming effect inopedza simba rinopinda uye rakaoma hunhu hwebundu maseru, ichipa theoretical fulcrum yekugadzirwa kweakasanganiswa epigenetic mishonga.

2.3 Immune Synergy: Kubvisa iyo "Invisibility Cloak" yePD-L1

Kunyanya kupandukira ndekwekuti chikwata chimwe chete chakaona kuti mannose inogona kunanga bundu immune immune system. Kuburikidza nekuongororwa kwehukuru spectrometry, vaongorori vakasimbisa kuti mannose inotadzisa kupeta chaiko uye membrane kugariswa kweprotein yePD-L1 nekukanganisa kushandurwa kwayo kweN-glycosylation. Iprotein yePD-L1, iyo inorasikirwa ne "amburera yekudzivirira" yeketani yeshuga, inowanzove yakasvibiswa uye yakasvibiswa, nokudaro ichibvisa chiratidzo chekudzivirira pamasero eT. Mune melanoma mbeva modhi, musanganiswa wemannose uye anti-PD-1 antibody yakawedzera bundu regression kusvika 78%, ichipfuura iyo yerapi imwe chete (Mufananidzo 2).

3.1 Milestones ye preclinical research

Mukuedza kwemhuka kwakawanda, mannose yakaratidza yakafara-spectrum anti-cancer kugona. Chikwata cheBritish chakapindira pancreatic cancer modhi mbeva ne20% mannose mvura yekunwa uye yakaona kuti bundu vhoriyamu kukura kwakanonoka kusvika 40%, uye pakanga pasina chakakosha chiropa kana chepfu yeitsvo. Zvinotonyanya kufadza, kana yakashandiswa pamwe chete negemcitabine, nguva yekupona yemakonzo yakawedzerwa ne2.3 nguva, zvichiratidza kukosha kwayo kwechemotherapy-sensitizing. Ongororo yakazvimirira yekusimbisa paMD Anderson Cancer Center muUnited States yakaratidza kuti mannose inoshanda zvakaenzana pakurwisa mhando dzegomarara senge katatu-negative rezamu uye glioblastoma.

Kunyangwe paine inonakidza preclinical data, miedzo yevanhu inotarisana nematambudziko akasiyana. Iyo Phase I yekiriniki yekuedza (NCT05220739) yakatangwa muna 2022 ndiyo yaive yekutanga kuongorora kuchengetedzwa kweoral mannose muvarwere vane mapundu akasimba akasimba. Yekutanga data inoratidza kuti varwere vari muzuva nezuva 5g dose boka vane kushivirira kwakanaka, uye inotenderera bundu DNA (ctDNA) mazinga mune dzimwe nguva akadzikira zvakanyanya. Nekudaro, iyo dosi payakakwira kusvika ku10g, vangangoita 15% yevarwere vakawana manyoka asina kusimba, zvichiratidza kukosha kwekugadzirisa dosing regimen.
