Definitions
- the measure of the activity at early time allows to predict accurately the response phenotype of a cell after a time when the contact of the sensitive cell populations with said cancer drug induced only little transcriptional response that would change its profile and allows to recover both non-responding and responding cells that eventually die when its response phenotype manifests itself.
- the cells are predicted responding for normalized average nuclear intensity > 75 th percentile of the population, preferably > 80 th , 85 th , 90 th , 95 th percentiles of the population and are predicted non-responding for normalized average nuclear intensity ⁇ 25 th percentile of the population, preferably ⁇ 20 th , 15 th , 10 th , 5 th percentiles of the population.
- the cells are predicted responding for cytoplasmic-nuclear ratio intensity ⁇ 25 th percentile of the population, preferably ⁇ 20 th , 15 th , 10 th , 5 th percentiles of the population and are predicted non-responding for cytoplasmic-nuclear ratio intensity > 75 th percentile of the population, preferably > 80 th , 85 th , 90 th , 95 th percentiles of the population.
- said combined preparation comprised a cancer drug agent, preferably death receptor targeted agent as described previously, and an inhibitor of Dynamin-l-like protein, preferably dynasore (CAS No. 1202867-00-2) or Mdivi-1 (CAS No. 338967-87-6).
- a cancer drug agent preferably death receptor targeted agent as described previously
- an inhibitor of Dynamin-l-like protein preferably dynasore (CAS No. 1202867-00-2) or Mdivi-1 (CAS No. 338967-87-6).
- Suitable dosage ranges for a compound that modulates the identified gene by the method described previously may be of the order of several hundred micrograms of the agent with a range from about 0.001 to 10 mg/kg/day, preferably in the range from about 0.01 to 1 mg/kg/day.
- the final number of cells included was: 1529 for control sample, 1481 for TRAIL 50mn 25ng/ml, 1631 for TRAIL 120mn lOng/ml, 1804 for TRAIL 120mn 25ng/ml and 2115 for TRAIL 120mn 40ng/ml.
- Cell cycle scores were calculated using Seurat CellCycleScoring function, based on previously published gene sets (Revinski et al, 2018). Each sample was first normalized to 10,000 UMIs, and variable features were selected using the vst method.
Abstract
La présente invention concerne un procédé in vitro d'identification d'un produit génique impliqué dans la destruction fractionnelle de populations de cellules sensibles aux médicaments après le traitement du médicament contre le cancer et une préparation combinée comprenant un médicament contre le cancer et un composé qui module l'expression ou l'activité du produit génique identifié par ledit procédé pour une utilisation dans le traitement contre le cancer pour augmenter ladite puissance de médicament contre le cancer et réduire le développement de la résistance au traitement contre le cancer.
