Features: treatment category
Chemotherapy is a treatment approach that uses drugs to target and kill rapidly dividing cells, primarily cancer cells. However, because many normal cells also divide quickly (such as those in the bone marrow, digestive tract, and hair follicles), chemotherapy can also affect these cells, leading to a range of side effects.

Main Classes of Chemotherapy Agents and Examples
Alkylating Agents:
-work by adding alkyl groups to DNA, which interferes with the DNA’s structure and prevents replication.
Examples: Cyclophosphamide, Ifosfamide, Melphalan, Chlorambucil, Busulfan.

Anti-metabolites:
-interfere with DNA and RNA synthesis by substituting for the normal building blocks of nucleic acids.
Examples: Methotrexate, 5-Fluorouracil (5-FU), Cytarabine, Gemcitabine, 6-Mercaptopurine.

Anti-microtubule Agents:
-interfere with the structures that separate chromosomes during cell division (mitosis). Examples: Paclitaxel, Docetaxel, Vincristine, Vinblastine.

Topoisomerase Inhibitors:
-target the enzymes topoisomerase I and II, which control the changes in DNA structure required for replication.
Examples: Etoposide (topoisomerase II inhibitor), Irinotecan (topoisomerase I inhibitor), Topotecan.

Cytotoxic Antibiotics:
-intercalate into DNA, inhibiting the replication of cancer cells.
Examples: Doxorubicin, Daunorubicin, Bleomycin, Mitoxantrone.

Platinum-Based Agents:
-contain platinum and cause cross-linking of DNA, which interferes with DNA repair and replication. Examples: Cisplatin, Carboplatin, Oxaliplatin.

Many chemotherapy agents exert their effects, at least in part, by inducing oxidative stress in cancer cells. They can increase ROS levels through several mechanisms:
-Direct generation of free radicals.
-Disruption of mitochondrial function, leading to increased production of ROS.
-Interference with the cell’s antioxidant systems.

-May want to avoid antioxidants 7 days bef
ore and 7 days after chemo.
Examples: NAC, Glutathione, Alpha Lipoic Acid, Vitamin E
-anti-oxidants known to have pro-oxidant effects (like Quercetin, Curcumin, etc.) should not be taken 2-3 days before and after chemo
-pro-oxidants known to bring good benefit to chemo can be continued during chemo. Examples are: Omega 3, Aremisia Annua, Silver NanoParticles.


Casp3, CPP32, Cysteinyl aspartate specific proteinase-3: Click to Expand ⟱

Type:
Also known as CP32.
Cysteinyl aspartate specific proteinase-3 (Caspase-3) is a common key protein in the apoptosis and pyroptosis pathways, and when activated, the expression level of tumor suppressor gene Gasdermin E (GSDME) determines the mechanism of tumor cell death.
As a key protein of apoptosis, caspase-3 can also cleave GSDME and induce pyroptosis. Loss of caspase activity is an important cause of tumor progression.
Many anticancer strategies rely on the promotion of apoptosis in cancer cells as a means to shrink tumors. Crucial for apoptotic function are executioner caspases, most notably caspase-3, that proteolyze a variety of proteins, inducing cell death. Paradoxically, overexpression of procaspase-3 (PC-3), the low-activity zymogen precursor to caspase-3, has been reported in a variety of cancer types. Until recently, this counterintuitive overexpression of a pro-apoptotic protein in cancer has been puzzling. Recent studies suggest subapoptotic caspase-3 activity may promote oncogenic transformation, a possible explanation for the enigmatic overexpression of PC-3. Herein, the overexpression of PC-3 in cancer and its mechanistic basis is reviewed; collectively, the data suggest the potential for exploitation of PC-3 overexpression with PC-3 activators as a targeted anticancer strategy.
Caspase 3 is the main effector caspase and has a key role in apoptosis. In many types of cancer, including breast, lung, and colon cancer, caspase-3 expression is reduced or absent.
On the other hand, some studies have shown that high levels of caspase-3 expression can be associated with a better prognosis in certain types of cancer, such as breast cancer. This suggests that caspase-3 may play a role in the elimination of cancer cells, and that therapies aimed at activating caspase-3 may be effective in treating certain types of cancer.
Procaspase-3 is a apoptotic marker protein.
Prognostic significance:
• High Cas3 expression: Associated with good prognosis and increased sensitivity to chemotherapy in breast, gastric, lung, and pancreatic cancers.
• Low Cas3 expression: Linked to poor prognosis and increased risk of recurrence in colorectal, hepatocellular carcinoma, ovarian, and prostate cancers.
