Are multiple cell states a general property of cancer?

5 important questions on Are multiple cell states a general property of cancer?

How does single cell RNA sequencing work in cancer analysis?

Single cell sequencing for cancer analysis
  1. From solid tissue, single cell are isolated
  2. RNA from it is taken and cDNA is made which are amplified
  3. form the single cell RNA sequencing, look at the single cel RNA expression and identify the uniek transcription states
  4. Identify cell type
    • See difference between cancer and non cancer cell

What is the application of single cell RNAseq?

  • Deconvolving heterogeneity cell population
  • Trajectory analysis of cell state transition
  • Network interference

What are the 3 major cellular subtypes in oligodendroglioma? And which type tumor do they have?

  • Stem-like (cycling cells)
  • astro-like (AC)
  • oligo-like (OC)
  • (undifferentated)


Developmental hierarchy of these tumor types can differ across tumor.
  • Higher grades + faster learning
  • Never study anything twice
  • 100% sure, 100% understanding

What are the two transcriptional states in melanoma?

Single cell RNA seq identifies 2 transcriptional states
  • AXL - mesenchymal type cells
  • MITF - lineage committed cells


Each melanoma includes two different cell types: ALX+ enriches during RAF/ERK inhibition treatment

What is the drug tolerant cell type in melanoma?

NCSC, is responsible for relapse
  • Trametinib ( MEK inhibitor)
  • RXR antagonist

combination of drug kills all cells

The question on the page originate from the summary of the following study material:

  • A unique study and practice tool
  • Never study anything twice again
  • Get the grades you hope for
  • 100% sure, 100% understanding
Remember faster, study better. Scientifically proven.
