Recombinant protein galectin-1 exposure to OM-1 cell proliferation: An experimental in vitro study

Research output: Contribution to journalArticlepeer-review


Aim: The aim of this study was to overcome the shortage of galectin-1 (Gal-1) protein and to determine cell proliferation by adding recombinant protein that has a high protein content of the squamous cell OM-1. Materials and Methods: A presented study was Experimental laboratory study. The role of recombinant protein galectin1 (rGal1) in combating squamous cell carcinoma of the OM1, as compared to HOC313 squamous cell carcinoma without exposure to rGal1, through the promotion of cell proliferation. An in vitro experiment was conducted on the following three groups: a negative control group using OM-1 cells, an intervention group comprising OM-1 cells to which 8 μg/mL r-Gal-1 was added, and a positive control incorporating HOC313 cells that were highly invasive. The proliferation level of the cells was measured by means of the optical density on a microplate reader on days 0, 1, 2, 3, and 4. In the three test groups, an increased proliferation rate was obtained on days 1, 2, 3, and 4 on OM-1, OM-1 + r-Gal-1, and HOC313. The statistical analysis was carried out using analysis of variance test, Kruskal-Wallis test, least significant difference test, and Mann-Whitney test. Results: The proliferation rate increased significantly (P 0.05) in the treatment group (OM-1 + r-Gal-1) as compared to the negative control group (OM-1). The positive control group (HOC313) experienced the highest degree of proliferation among the three groups. Conclusion: Gal-1 is a protein that plays a key role in the processes of cancer metastasis and invasion.
