Novo upanje za zdravljenje določenih vrst raka pri ljudeh in mačkah

Nova študija, objavljena v reviji Science nakazuje, da mačji prijatelji lahko ponudijo tudi namige za boljše zdravljenje določenih vrst raka.

Znanstveniki so preučevali raka pri mačkah in odkrili pomembne vzporednice z razvojem bolezni pri ljudeh.

Nekatere pretekle študije so že pokazale podobne povezave med psi in ljudmi, a malo raziskav se je osredotočalo na mačke.

»Mačke, tako kot psi, z ljudmi delijo okolje s podobnimi vrstami onesnaženja, na primer pasivno kajenje. Razvijejo tudi druge bolezni, kot jih mi, ko zbolimo za rakom,«

je povedala soavtorica študije Louise van der Weyden, znanstvenica z britanskega inštituta Wellcome Sanger.

Nova odkritja pri mačkah vlivajo novo upanje

Mednarodna raziskovalna skupina je analizirala vzorce rakavih tumorjev skoraj 500 domačih mačk iz petih držav. Zajeli so 13 vrst raka (med drugim rak možganov, dojk, pljuč in kože). Ker se rak razvije iz genskih mutacij, so raziskovalci v DNK tumorskih celic mačk iskali markerje, ki so v humani medicini že znani. Pri več kot polovici analiziranih mačjih mlečnih tumorjev so ugotovili mutacijo v genu FBXW7, ki je že identificiran tudi pri ljudeh.

»Ta vrsta mutacije pri ženskah z rakom dojk ni pogosta, je pa zelo agresivna,« je povedala znanstvenica.

Dodala je, da je za ženske to odkritje odlično, ker bi lahko vodila k novim oblikam zdravljenja. Švicarski raziskovalci so izvedli dodatne poskuse na teh vzorcih in ugotovili, da sta bili dve kemoterapiji zelo učinkoviti pri tumorjih s to specifično mutacijo. Rezultate morajo potrditi z nadaljnjimi raziskavami, ki bi lahko prinesle koristi tako ženskam kot mačkam, saj sta ti zdravili za uporabo pri ljudeh in živalih že odobreni, je dejala Van der Weydenova.

Kar bi lahko pomenilo zmagovalno kombinacijo za ljudi in naše živalske prijatelje.

_hjClosedSurveyInvites Hotjar cookie. This cookie is set once a visitor interacts with a Survey invitation modal popup. It is used to ensure that the same invite does not re-appear if it has already been shown. 365 days _hjDonePolls Hotjar cookie. This cookie is set once a visitor completes a poll using the Feedback Poll widget. It is used to ensure that the same poll does not re-appear if it has already been filled in. 365 days _hjMinimizedPolls Hotjar cookie. This cookie is set once a visitor minimizes a Feedback Poll widget. It is used to ensure that the widget stays minimizes when the visitor navigates through your site. 365 days _hjDoneTestersWidgets Hotjar cookie. This cookie is set once a visitor submits their information in the Recruit User Testers widget. It is used to ensure that the same form does not re-appear if it has already been filled in. 365 days _hjIncludedInSample Hotjar cookie. This session cookie is set to let Hotjar know whether that visitor is included in the sample which is used to generate funnels. 365 days _hjShownFeedbackMessage This cookie is set when a visitor minimizes or completes Incoming Feedback. This is done so that the Incoming Feedback will load as minimized immediately if they navigate to another page where it is set to show. 365 days _hjid Hotjar cookie. This cookie is set when the customer first lands on a page with the Hotjar script. It is used to persist the Hotjar User ID, unique to that site on the browser. This ensures that behavior in subsequent visits to the same site will be attributed to the same user ID. 365 days _hjRecordingLastActivity This should be found in sessionStorage (as opposed to cookies). This gets updated when a visitor recording starts and when data is sent through the WebSocket (the visitor performs an action that Hotjar records). Session hjTLDTest When the Hotjar script executes we try to determine the most generic cookie path we should use, instead of the page hostname. This is done so that cookies can be shared across subdomains (where applicable). To determine this, we try to store the _hjTLDTest cookie for different URL substring alternatives until it fails. After this check, the cookie is removed. Session _hjUserAttributesHash User Attributes sent through the Hotjar Identify API are cached for the duration of the session in order to know when an attribute has changed and needs to be updated. Session _hjCachedUserAttributes This cookie stores User Attributes which are sent through the Hotjar Identify API, whenever the user is not in the sample. These attributes will only be saved if the user interacts with a Hotjar Feedback tool. Session _hjLocalStorageTest This cookie is used to check if the Hotjar Tracking Script can use local storage. If it can, a value of 1 is set in this cookie. The data stored in_hjLocalStorageTest has no expiration time, but it is deleted immediately after creating it so the expected storage time is under 100ms. N/A _hjptid This cookie is set for logged in users of Hotjar, who have Admin Team Member permissions. It is used during pricing experiments to show the Admin consistent pricing across the site. Session _hjAbsoluteSessionInProgress The cookie is set so Hotjar can track the beginning of the user's journey for a total session count. It does not contain any identifiable information. 30 minutes
