Task: Answer Verification
Input (English): Question: Do advanced glycation end products inhibit the expression of collagens type I and III by human gingival fibroblasts?
Answer: AGEs may suppress the cell viability of HGFs and downregulate the expression of types I and III collagen by the cells. Further investigations are warranted to clarify the molecular mechanisms of AGEs in the regulation of cell function and collagen metabolism in patients with diabetes and periodontitis.
Output (English): yes
