Cancer Flashcards
What happenens in g1
Cell grows and lives normally
What happens in synthesis
Chromosomes duplicate to get ready for replication
What happens in G2
Cells grow and get more cytoplasm and organelles to prepare for division
What happens in cancer
Checkpoints are ignored making the cell division go out of control
Controls cell division to prevent cancer
Proto-oncogene
Stops tumors from forming to prevent cancer
Tumor suppressor gene
Mutated proto-oncogene that causes cancer
Oncogene
What happens when proto-oncogenes turn into oncogene
Increases enzyme/ protein activity
Regulation loss
Increased protein concentration
What kind of gene is p53
Tumor suppressor
Importance of p53
Guardian of genome
Responsible for recognizing uncontrolled growth
Induces apoptosis/programmed cell death
Cells stop dividing when they are too close, when broken, pile up to form tumor
Contact inhabition
The number of times a cell can divide without damaging dna
Replicative senescence
X ray info
Ionizing radiation
2d
Dense bone/tissue structure
Noninvasive and cheap
Small cancer risk
Ct info
X-ray from many angles/cross sections
Bone, soft tissues blood vessels
Chest, abdomen, pelvis, spine
3d
Fast, noninvasive
MRI info
Cross sections
3d
Used magnets and radio waves
Soft tissue
See inside brain bones and ligaments
Diagnose cancer and brain and heart conditions
