Cancer Flashcards
support cells in tissues, blood vessels, neurons, connective tissue
stromal cells
specific/specialized cells to tissues ex cardiomyocyte
parenchymal cells
cells derived from neural crest/mesenchyme
mesenchymal cells
cells that give rise to connective tissue
mesenchymal cells
oma
benign tumor
carcinoma
malignant tumor of EPITHELIAL origin
adenocarcinoma
Malignant tumor of GLANDULAR tissue
sarcoma
malignant tumor of MESENCHYMAL origin
blastoma
malignant tumor of PRECURSOR cells
leukemia
lymphoma
mealnoma
all malignant
looks like where it came from
well differentiated
doesn’t look like any cell in the body
Undifferentiated
well demarcated
benign, can see borders
poorly demarcated
malignant, cannon differentiate borders
locally invasis
malignant
poorly differentiated
malignant
initial carcinogenic induced mutation that gets everything started
daughter cells have same mutation, and they can pick up new mutations
Transformation
mutated cells continue to grow and divide and continue to make more genetically mutated cells
progression and proliferation
has abnormal activity or is expressed at abnormal levels
oncogene
people cannot be born with one ____________ but can be born with one ______________.
mutant oncogene, mutant tumor supressor gene
TUMOR SUPRESSOR or ONCOGENE:
Bcl-2 - b cell lymphoma
ONCOGENE
b cell lymphoma
TUMOR SUPRESSOR or ONCOGENE:
BRCA 1 and 2
TUMOR SUPRESSOR
- breast cancer
TUMOR SUPRESSOR or ONCOGENE:
HER2 / NEU
ONCOGENE
ovarian and breast cancer, ependymal growth factor
TUMOR SUPRESSOR or ONCOGENE:
APC
TUMOR SUPRESSOR
colorectal
TUMOR SUPRESSOR or ONCOGENE:
RB1
TUMOR SUPRESSOR
retinoblasotma
TUMOR SUPRESSOR or ONCOGENE:
N- MYC
ONCOGENE:
neuroblastoma
TUMOR SUPRESSOR or ONCOGENE:
C-Myc
ONCOGENE:
burkitt lymphoma and others
TUMOR SUPRESSOR or ONCOGENE:
RAS
ONCOGENE
30 - 30% of all cancers
TUMOR SUPRESSOR or ONCOGENE:
MSII
TUMOR SUPRESSOR
colorectal/ endometrial, gastric
TUMOR SUPRESSOR or ONCOGENE:
NF1 / NF2
TUMOR SUPRESSOR
neuroblastoma
How does RAS transform from a proto-oncogen to an oncogene
loses its ability to convert GTP to GDP - RAS is now permanently on and the cell is SELF SUFFICIENT
Tow hit hypothesis applies to ________.
insensitivity of anti-growth signals
example = RB- retinoblastoma gene
what gene is in charge of evading apoptosis
p53
when the p53 gene is mutated the cell cycle is never _______, so mutated cells continue to proliferate
stopped
limitless replicative potential
telomerase
sustained angiogenesis
VEGF
Cancer cells must exhibit __________. they have to chew through the ____________.
Cancer cells use _____________ to get through the collagen of the membrane and secretes ____________ and attaches itself to ______________ to pull through the basement membrane.
contact inhibition
basement membrane
type IV collagenase
proteolytic enzymes
fibinolectin
E6 binds up
RB
E7 binds up
p53
disable proteins, but DO NOT effect the gene
E6 and E7
strains NOT covered by HPV vaccine that cause cervical cancer
35 and 31
strains covered by HPV vaccine that cause cervical cancer
16 and 18 cause 70% of cervical cancers
strainscovered by HPV vaccine that cause genital warts
6 and 11
chemotherapy targets
rapidly dividing cells
because all hematopoietic stem cells are effected by chemotherapy, we will see_________.
Anemia and Neutropenia
when does chemo brain stop?
when chemo stops - chemo actually doesn’t have the ability to reach the CNS
______________ helps prevent resistant cells
Combination therapy
starvation due to nutrients going to cancer
cachexia
