TOP1, Topoisomerase I: Click to Expand ⟱
Source:
Type:
Topoisomerase I (TOP1) is an essential nuclear enzyme involved in relieving DNA supercoiling during replication and transcription.
• Elevated TOP1 expression has been observed in several tumor types, such as colorectal, ovarian, breast, and lung cancers.
• Increased TOP1 levels may correlate with higher proliferation rates, as actively dividing tumor cells require efficient relief of DNA.

• In some cancers, high TOP1 expression has been associated with aggressive tumor behavior, higher grade, and potentially poorer clinical outcomes. This may be due in part to increased proliferation and/or a greater propensity for genomic instability.
• In other contexts, TOP1 expression might indicate sensitivity to TOP1-targeted therapies. For example, tumors with high TOP1 activity may respond better to chemotherapeutic agents (e.g., irinotecan) that target the enzyme, potentially improving outcomes when appropriate treatment is administered.

TOP1 is a critical enzyme in maintaining DNA integrity whose expression in cancers can reflect tumor proliferation and genomic instability. While high TOP1 expression is often associated with aggressive tumor behavior and poorer prognosis in several cancer types, it also has therapeutic relevance because tumors with elevated TOP1 may be more sensitive to TOP1 inhibitors.

2906- LT,    Luteolin, a flavonoid with potentials for cancer prevention and therapy
- Review, Var, NA
*Inflam↓, anti-inflammation, anti-allergy and anticancer, luteolin functions as either an antioxidant or a pro-oxidant biochemically
AntiCan↑,
antiOx⇅, With low Fe ion concentrations (< 50 μM), luteolin behaves as an antioxidant while high Fe concentrations (>100 μM) induce luteolin's pro-oxidative effect
Apoptosis↑, induction of apoptosis, and inhibition of cell proliferation, metastasis and angiogenesis.
TumCP↓,
TumMeta↓,
angioG↓,
PI3K↓, , luteolin sensitizes cancer cells to therapeutic-induced cytotoxicity through suppressing cell survival pathways such as phosphatidylinositol 3′-kinase (PI3K)/Akt, nuclear factor kappa B (NF-κB), and X-linked inhibitor of apoptosis protein (XIAP)
Akt↓,
NF-kB↓,
XIAP↓, luteolin inhibits PKC activity, which results in a decrease in the protein level of XIAP by ubiquitination and proteasomal degradation of this anti-apoptotic protein
P53↑, stimulating apoptosis pathways including those that induce the tumor suppressor p53
*ROS↓, Direct evidence showing luteolin as a ROS scavenger was obtained in cell-free systems
*GSTA1↑, Third, luteolin may exert its antioxidant effect by protecting or enhancing endogenous antioxidants such as glutathione-S-transferase (GST), glutathione reductase (GR), superoxide dismutase (SOD) and catalase (CAT)
*GSR↑,
*SOD↑,
*Catalase↑,
*other↓, luteolin may chelate transition metal ions responsible for the generation of ROS and therefore inhibit lipooxygenase reaction, or suppress nontransition metal-dependent oxidation
ROS↑, Luteolin has been shown to induce ROS in untransformed and cancer cells
Dose↝, It is believed that flavonoids could behave as antioxidants or pro-oxidants, depending on the concentration and the source of the free radicals
chemoP↑, may act as a chemopreventive agent to protect cells from various forms of oxidant stresses and thus prevent cancer development
NF-kB↓, We found that luteolin-induced oxidative stress causes suppression of the NF-κB pathway while it triggers JNK activation, which potentiates TNF-induced cytotoxicity in lung cancer cells

P450↓, Recently, it was determined that luteolin potently inhibits human cytochrome P450 (CYP) 1 family enzymes such as CYP1A1, CYP1A2, and CYP1B1, thereby suppressing the mutagenic activation of carcinogens
CYP1A1↓,

TumCCA↑, Luteolin is able to arrest the cell cycle during the G1 phase in human gastric and prostate cancer, and in melanoma cells
