Summary
Matrix metalloproteinase-2 (MMP-2) is overexpressed in prostate cancer (PCa) tissues compared to benign prostatic hyperplasia (BPH). MMP-2 expression is linked to higher PCa malignancy, including Gleason Score and clinical stages.
Area of Science:
- Oncology
- Biochemistry
- Molecular Biology
Background:
- Matrix metalloproteinase-2 (MMP-2) is implicated in various cancers.
- The prognostic significance of MMP-2 in prostate cancer (PCa) is debated.
- Understanding MMP-2's role is crucial for PCa diagnosis and prognosis.
Purpose of the Study:
- To conduct a meta-analysis investigating the association between MMP-2 expression and PCa.
- To clarify the prognostic value of MMP-2 expression in prostate cancer.
- To determine if MMP-2 expression correlates with PCa malignancy indicators.
Main Methods:
- A meta-analysis of published case-control studies was performed.
- Studies were identified through searches of PubMed, Cochrane Library, and CNKI up to July 2015.
- Odd ratios (ORs) and 95% confidence intervals (CIs) were used to assess associations.
Main Results:
- Eight studies comprising 675 patients were included.
- MMP-2 expression was significantly higher in PCa tissues than in benign prostatic hyperplasia (BPH) tissues (P<0.00001).
- MMP-2 expression showed significant associations with Gleason Score (P=0.002) and clinical stages (P=0.02), but not with serum PSA (P=0.43).
Conclusions:
- MMP-2 is demonstrably overexpressed in prostate cancer tissues.
- MMP-2 expression is a significant indicator of PCa malignancy grade.
- Further research may elucidate MMP-2's precise role in prostate cancer progression.

5.1K
The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.

5.4K
Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the...
