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.
