Module 4 Flashcards
What are totipotent stem cells
Stem cells present from fertilization until 4 cell stage
What are pluripotent stem cells
AKA embryonic stem cells
Can differentiate all endo, meso, and ectoderm cells
What are multipotent stem cells
AKA adult stem cells
Can differentiate to a small number of cell types
What are unipotent stem cells
Terminally differentiating stem cells
Which stem cells can revert back progression
Multipotent to pluripotent like stem cells given the correct stimuli
What stimuli are needed to make adult stem cells like embryonic
KLF
MYC
OCT4
SOX
“GO” factors for the cell cylce
Cyclins
Cyclin dependent kinases
Polo like kinases
“STOP” factors for cell cycle
TSG’s
RB
p53
CDK inhibitors
Cyclin - CDK - G1 active phase
Cyclin D (D1, D2, D3) - CDK4/CDK6
Cyclin - CDK - G1/S active phase
Cyclin E - CDK2
Cyclin - CDK - S active phase
Cyclin A - CDK2/CDK1
Cyclin - CDK - G2, M active phase
Cyclin B/A - CDK1
What are the ways virus’s can cause cancer
Insertion of oncogene into DNA (Acutely Transforming Retrovirus)
Insertion of promoter that upregulates hallmarks leading to cancer (Slowly Transforming Retrovirus)
What virus causes Burkitt’s or Hodgkin’s lymphomas
Epstein-Barr (EBV)
What virus causes cervical cancer
Human Papilloma 16 (HPV)
