Ka maʻi maʻi koko kamaliʻi: ke kuleana nui o nā meaʻai

i kakauia ma hoʻoponopono

ʻO ka molecular building blocks o ka nui o nā protein holoholona, ​​​​ka amino acid valine, ke kuleana nui i ka ulu ʻana o ka maʻi kanesa i ʻike ʻia ma ka T cell acute lymphoblastic leukemia, hōʻike ʻia kahi noiʻi hou.

Alakaʻi ʻia e nā mea noiʻi ma NYU Langone Health, kāna Keʻena ʻOihana, a me ka Laura a me Isaac Perlmutter Cancer Center, ua hōʻike ʻia ka haʻawina e ʻoi aku ka ikaika o nā genes i ka hoʻohana ʻana i ka valine i loko o nā cell cancerous T ma mua o nā cell T maʻamau.                                                                                                       

ʻO ka pale ʻana i kēia mau genes pili i ka valine ʻaʻole i alakaʻi wale i ka valine i hoʻemi ʻia i loko o nā keʻena T koko maʻi leukemia, akā ua hoʻopaʻa pū ʻia kēia mau ʻōpū mai ka ulu ʻana i ka lab. He 2 pakeneka wale nō o nā pūnaeau T ma'i 'a'ai i ola.

Eia hou, ua manaʻo nā hoʻokolohua e hoʻololi (mutations) i ke code DNA o ka gene NOTCH1, ka mea maʻamau i ʻike ʻia i nā poʻe maʻi e hoʻomohala nei i ka maʻi leukemia, e paipai i ka ulu ʻana o ka maʻi kanesa ma ka hoʻonui ʻana i nā pae valine.

Hoʻopuka ʻia ma ka puke pai Nature online Dec. 22, ua pili ka noiʻi i nā hoʻokolohua i loko o nā pūnaewele leukemia kanaka i ulu i loko o ke keʻena hana a hoʻololi pū ʻia i loko o nā ʻiole a laila hoʻomohala i kēia maʻi kanesa, nona ka kumu i loko o nā keʻokeʻo keʻokeʻo i loko o ka iwi iwi.

Ua hōʻike ʻia nā hoʻokolohua ʻē aʻe i ka hānai ʻana i nā ʻiole leukemic i nā meaʻai haʻahaʻa-valine no ʻekolu pule i hoʻopau i ka ulu ʻana o ka maʻi maʻi. ʻO ka ʻai hoʻi i hoʻemi i ka holo ʻana o nā maʻi maʻi maʻi koko ma ka hapa liʻiliʻi a ma kekahi mau mea i nā pae undetectable. ʻO ka hoʻokaʻawale ʻana, ʻo ka hoʻokomo hou ʻana i ka valine i nā meaʻai i alakaʻi i ka piʻi ʻana o ka maʻi kanesa.

"Ke hōʻoia nei kā mākou noiʻi ʻana ʻo T cell acute lymphoblastic leukemia e hilinaʻi nui ʻia i ka lako o valine a hiki i ka hemahema o valine ke hoʻopaʻa i ka holomua o kēia maʻi kanesa," wahi a ka mea noiʻi alakaʻi alakaʻi ʻo Palaniraja Thandapani, PhD, he hoa postdoctoral ma NYU Grossman School of Medicine and ʻo ia ʻo Perlmutter Cancer Center.

Ua hoʻolālā ka hui noiʻi i ka makahiki aʻe e hoʻāʻo ai inā he mea lapaʻau maikaʻi nā meaʻai haʻahaʻa i nā meaʻai waiwai nui o valine, e like me ka ʻiʻo, ka iʻa, a me nā pīni. Hiki ke loaʻa nā meaʻai haʻahaʻa-valine, wahi a Thandapani, no ka mea, ke hoʻohana ʻia nei lākou no ka mālama ʻana i nā ʻano like ʻole o ka waikawa i loko o ke kino i hoʻopaʻa ʻia i nā maʻi genetic e pili ana i ka metabolism o ka ʻōpū.

Wahi a ka mea noiʻi noiʻi nui ʻo Iannis Aifantis, PhD, ʻo ka hoʻolālā hoʻāʻo e hui pū i ka lāʻau ʻai me ka venetoclax, he lāʻau lapaʻau i ʻae ʻia no ka hoʻohana ʻana ma ʻAmelika no ka hapa nui o nā ʻano leukemia.

He mea nui ka hui ʻana o ka lāʻau, ʻōlelo ʻo ia, no ka mea, ʻaʻole hiki ke hoʻomau ʻia nā mea ʻai i ka wā lōʻihi. ʻO kēia ma muli o ka hiki ke ʻike ʻia no ka pau ʻana o ka ʻiʻo a me ka pōʻino o ka lolo mai ka hemahema o ka valine lōʻihi.

"ʻO kā mākou hoʻokolohua lapaʻau e pili ana i ka hoʻohana ʻana i nā meaʻai haʻahaʻa-valine e hōʻemi i ka nui o nā cell T me ka maʻi leukemia lymphoblastic acute i kahi pae haʻahaʻa loa e hiki ai i nā lāʻau lapaʻau ke hoʻopaʻa pono i ka piʻi ʻana o ka maʻi kanesa," wahi a Aifantis, ka Hermann M. Biggs Professor a me ka noho o ka Keʻena o ka Pathology ma NYU Grossman a me Perlmutter.

Ua ʻōlelo ʻo Aifantis he nui nā poloka kūkulu hale maʻamau, ʻo ia hoʻi nā protein, nucleotides, a me nā momona momona, pono e ulu a laha ka maʻi kanesa. Ma kahi o ka hapalua o nā ʻakika amino ʻē aʻe, ʻoi aku ka nui o ka lysine kiʻekiʻe, ua hoʻopili ʻia i nā maʻi maʻi maʻi, akā ʻaʻole ʻike ʻia ko lākou kuleana pololei. Ua ʻōlelo ʻo ia ua hoʻāʻo ʻia nā hoʻolālā meaʻai wale nō no ka mālama ʻana i ka maʻi kanesa no nā makahiki he nui me nā hōʻike ʻepekema liʻiliʻi o kekahi pono. Ua ʻōlelo ʻo ia e pono ana ka noiʻi hou aʻe, me ka hoʻāʻo hoʻokolohua lapaʻau i hoʻolālā ʻia e ka hui, ma mua o ka hiki ke ʻōlelo ʻia i nā alakaʻi lapaʻau.

Ua manaʻo ka American Cancer Society he ʻoi aku ma mua o 1,500 ʻAmelika, ka hapa nui o nā keiki, make i kēlā me kēia makahiki mai ka T cell acute lymphoblastic leukemia. He 5,000 hou e ʻike hou ʻia. ʻO kēia ʻano maʻi maʻi maʻi e pili ana i ka hapahā o nā maʻi leukemia a pau.

Hāʻawi ʻia ke kākoʻo kālā no ke aʻo ʻana e nā National Institutes of Health nā hāʻawi P30CA016087, P01 CA229086 a me R01 CA228135; ka Leukemia & Lymphoma Society; ʻO ka papahana NYSTEM o New York State Department of Health; a me ka American Association for Cancer Research Incyte Corporation Leukemia Research Fellowship.

He mea aʻoaʻo ʻo Aifantis no Foresite Labs, kahi ʻoihana mālama ola olakino i hoʻokumu ʻia ma Kapalakiko e loaʻa ana nā pono kālā i ka hoʻomohala ʻana i nā maʻi leukemia. ʻO Aristotelis Tsirigos, PhD, ka mea noiʻi noiʻi, lawelawe ma ke ʻano he kākāʻōlelo ʻepekema no Intelligencia.AI ma New York City, kahi hui polokalamu e pili ana i ka aʻo ʻana i ka mīkini i ka hoʻomohala ʻana i ka lāʻau lapaʻau. Ke mālama ʻia nei nā ʻōlelo o kēia mau hoʻonohonoho e like me nā kulekele o NYU Langone.

Ma waho aʻe o Thandapani, ʻo Aifantis a me Tsirigos, ʻo nā mea noiʻi ʻē aʻe o NYU Langone i komo i loko o ke aʻo ʻana he mau mea noiʻi alakaʻi alakaʻi ʻo Andreas Kloetgen; Matthew Witkowski; a me Christina Glytsou; a aʻo pū me nā mea noiʻi ʻo Anna Lee; Eric Wang, Jingjing Wang; Sarah LeBoeuf; Kleopatra Avrampou; a me Thales Papagiannakopoulos.

  • Mwen la pou temwaye sa gwo chantye òtograf sa a te fè pou mwen. Mwen pa janm kwè nan jete eple, jouk lè mwen te tante eseye li. Mwen menm ak madanm mwen te gen anpil pwoblèm pou viv ansanm, li pap toujou fè m kontan paske li te renmen yon lòt gason andeyò relationship nou, mwen te fè tout sa m kapab pou m asire ke madanm mwen kite fanm sa a men plis. Mwen pale ak li plis li fè m tris, kidonk maryaj mwen kounye a ap mennen nan divòs paske li pa banm atansyon ankò. Se konsa, ak tout doulè sa yo ak agoni, mwen deside contactte mò sa a pou wè si bagay yo ka mache ant mwen menm ak madanm mwen ankò. sa a jete eple ki te yon nonm te di m 'ke madanm mwen se reyèlman anba yon gwo eple ke li te cham pa kèk maji, se konsa li te di m' ke li te pral fè tout bagay sa yo nòmal tounen. li te fè madanm lan epi apre 5 jou madanm mwen te chanje nèt li menm eskize ak fason li te tretem ke li pat tèt li, mwen vrèman remèsye mesye sa a non li se Doktè li te mennen madanm mwen tounen vin jwenn mwen. Mwen vle nou tout kontakte li ki gen nenpot pwoblèm ki gen rapò ak pwoblèm maryaj ak pwoblèm relasyon li pral rezoud li pou ou. imèl li [pale ʻia ka leka uila] oswa whatsap l '+2347051758952 se li se yon nonm ak gwo li. swete w bon moman.
