“Ba ta da siffar dukum, tana kyalli da haske.”

Ta haifi tunkiya Sharon; mai karfi da koshin lafiya mai silikin fatar ulu, wadda masu bincike ke ganin za ta warware musu rudanin da ke tattare da yamutsin gashinta, har zuwa yadda za su gano gashin mutum a wurin da aka aikata laifi da zayyana mai sheki da ulu mai taushi, har zuwa sirrrin lullube gashin jiki da managartan kayan shafe-shafe.

Tsawon gashi.

Tare da cewa samar da madara da tsawon gashi al’amarin da mutane ke yi kamar sauran dabbobi masu shayarwa, wadanda suka hada da ‘yan uwa na nesa, da suka hada da masu nasa kwai da shayarwa da dabbobin ruwan da ke nasa kwai da shayarwa, a cewar jagoran nazarin gashin fata na AgResearch, Duane Harlands.

Gashin dabbobi masu shayarwa iri-iri ne.

Ulun fatar tunkiya ya yi kama da namu, kuma ya dara jaba, a cewar Harlands. Wannan ne dalilin muhimmancin binciken tunkiya don nazarin gashin mutum (ta yadda masana kimiyya za su zabi nau’in tunkiya za su yi wa barbarar hayayyafa, inda aikata hakan ga mutane na zai tayar da hankali).

Alamun da ke tattare da gashi da suka hada da tsayinsa ko kwanciyarsa ko dalilin da ya sa na wasu yake mitsi-mitsi lamari ne da ke da rikitarwa, a cewar Harland. “Daukacin silin gashin halittu, misali siliki ko auduga ko wani abu daban, gashi na daya daga abubuwa mafi cukurkudewa,” inji shi.

“Yana da matukar wuyar sha’ani ta yadda muka gaza fahimtar tsarinsa kimar ma’aunin nanometer, tare da mabambantan sinadaran protein da ke da tasiri kan tsarinsa.

“Misali, mene ne dalilin qanqancewar gashin wasu mutane lokacin raba? Lamarin na da muihimmanci ga kamfanonin sarrafa kayan kwalliyar jiki, tunda ba mu fahimci hakikanin abin da ke haifar wa mutane hakan ba. Wannan tunkiya ta bayar da haske kan haka,” inji Harlland.

A bidiyon sama na AgResearch, inmda Jeff Plowman ya nuna bambancin ulun gashin Sharon da na wata tunkiya.

Muhimmin tsarin da gashi ke bi shi ne xaurin silin masu kyau akwance suke, wadanda suke a mike suna da kauri a hargitse. Ulun gashin tunkiya, musamman mai kyau nau’in na Spain ya fi kwanciya fiye da gyrarren gashin mutum, shi ya sa kayan da aka yi da gashin fatan dabba ke da dadin sakawa, sabanin guntuwar rigar da aka yi da gashin mutum da za ta tsireka.

Sai dai dabobi masu jirkitattun kwayoyin halitta irin Sharon sun sha bamban, inda suke da gashi mai kyau kwantacce da miqaqqe. Wannan shi ya bai wa masu bincike dama ta daban su yi nazarin alamomin biyu daban-daban, ta yiwu ma su gano kwayoyin halittar da suka fi tasirin samar da mikakken gashi da sauran al’amuran da ke tattare da siffarsu.

Irin Sharon na n uni da cewa mikakken gashin fatarta ta yiwu qwayoyin halittarsa sun jirkice, a cewar Harlands, amma mikakken gashin mutum na bin tsarin da aka sani shi ya sa yake yamutsatse fiye da na ‘yan uwansa kwantance. Mikakken gashin mutum na iya kauce wa kamuwa da cuta wadanda tunkiya irin Sharon kan yi fama da ita, lamarin da ke bayyana dalilin watsewarsi.

Kuma akwai mutanen da ke gadon kwayoyin halittar cuituttuka, wadanda ke kama mutanen da ke da jirkitattun kwayoyin halittar mikakken gashin ulu irin na tunkiya, a cewar Harland.

Warware matsalar kwayoyin halittar Sharon wata rana za a samu dabarun magance cututtukan mutane.

“Akwai cututtukan mutane wadanda suka yi kama da na tunkiyarmu mai jirkitacciyar kwayar halitta, cewar Harland.

“Za ka samu mutane masu cututtukan fata ko matsaloli tatttare da hakoransu da gashinsu, kuma a kan samu cewa kwayar halittar ‘keratin’ na nakasa sai daukacin zuri’a su kasance marasa gashi, a wani lokacinma har da rashin kumba.”

Kuma a Amurka, wasu masu bincike na amfani da kwayoyin halittar mutum don samar da gashi.

Wannan zai taimaka wa masu bincike a wajen da aka aikata laifi su gano yanayin gashi wani mutum bisa nazarin kwayoyin halitta.

Cikin gaugawa masu bincike a New Zealand na son taimaka wa manoma kamar na Otago, wanda ya fara gano “akuya-kuya-tunkiya-tunkiya.”

Manoman da ke kiwon awaki na kokarin samun kudi daga fata mara nagarta, amma idan manoman da ke kiwon awaki suka karkata zuwa ga shanun da ke samar da madara yawan hada-hadar kiwo za ta cutar da muhalli.

Duk da cewa jirkitar Sharon ba bakon abu ba ne tashin farko, bambancin karara yake in an kwatanta da wata tunkiyar rinta.

Plowman da Harland na son manoman da ke kiwon awaki su samu gwaggwabar riba daga dabbobi kadan masu nagarta.

Wannan na nuni da cewa yin barbarar Sharon zai samar da kwararan nau’ukan tunkiya mabambanta.

Wata rana Plowman zai yi hanqoron ganin ‘yan kwalisar tallata kayan ado za su yi takun yangar jan hangali a dandamalin Paris, sanye da tufafin alfarma masu tsada wadanda aka samar bisa nazarin Sharon.

“Idan za ka iya samar da managarciyar fata mai kyallin gashi daga jikin tunkiya, wadda ba ta da rauni kamar lalacewar kofato…” a hasashen Plowman.

Yanzu Sharon na rayuwa ne a “wani wuri kamar na shakatawa’ kusa da birnin Christchurch, a Arewacin Otago a tsibirin Kudancin New Zealand.

A daminarta ta farko, masu bincike sun yi matar rigar sanyi da dakin da aka gina mata da abincin dabbobi don kariyar iska, wanda ta cinye.

Masu kula da ita sun rika yi wa dabbar ‘yar shekara uku aski akai-akai don gudun ka da ulun gashinta na daban ya valvalce. Sun rika sa’ido a duk matakin da ta shiga damuwa.

Yayin da tauraruwar bincikensu ke cin abinci a wajen kiwo, Plowman da Harland da wasunsu a AgResearch sun yi zayyanar fasalin 3D na tsarin ulun gashinta ta hanyar amfani da katafaren managarcin madubin likita.

Ba da daxewa ba suke shirin jeranta kwayoyin halittarta.
