This study investigates the impact of Porphyra sp. extracts on HT29 cell line growth and
viability at reduced serum conditions. The concentration-dependent effects of
phycobiliproteins (PBPs) on cell proliferation were examined over various time intervals.
Lower concentrations of PBPs (20 μg/mL) demonstrated an increase in HT29 cell viability
after 48 hours and 5 days of cultivation at reduced serum concentration (final serum
concentration was in the range from 5 to 8%). This suggests a potential positive influence
on cell proliferation, likely due to their antioxidant properties. Conversely, higher
concentrations of PBPs exhibited inhibitory effects on cell growth, possibly due to
cytotoxicity at elevated levels. Remarkably, when HT29 cells were cultured solely in algal
extract without fetal calf serum (FCS), complete growth inhibition was observed after 72
hours. This finding underscores the insufficient nutrient and growth factor provision of
PBPs alone for sustaining cel...l viability. Morphological differences observed in cells
cultured with 70 μg/mL of PBPs indicated potential alterations in cellular morphology.
Notably, 70 μg/mL of PBPs in RPMI medium with 5% FCS displayed growth inhibition
compared to the control (5% FCS). Furthermore, we assessed HT29 cell adaptability to
changes in FCS concentration and PBP supplementation. Cells incubated under varying
FCS and PBP conditions were subcultured into RPMI medium with lower FCS
concentration and PBPs from Porphyra. The viability of cells following subculturing
indicated sustained adaptability to reduced FCS levels. Overall, this study provides
valuable insights into the concentration-dependent effects of PBPs from Porphyra extracts
on HT29 cell growth and viability. The findings underscore the potential benefits of PBPs
at lower concentrations for cell proliferation at reduced serum conditions and reveal the
adaptability of HT29 cells to changing culture conditions.
