Fig 4. STRING diagram representing protein interaction pathway derived from the 27 proteins significantly altered at 48 h after the incubation of HK-2 cells with HG-Hypoxia in comparison to NG-Normoxia.

The average local clustering coefficient as reported by STRING is 0.703. Proteins in yellow belong to the glycolytic process; proteins in red belong to the ATP metabolic process; proteins in blue belong to the cytoskeleton organization; and proteins in green belong to the regulation of organelle organization.
