RETRACTION: Circ_0087199 Depletion Attenuates Lipopolysaccharides‐Induced Human Periodontal Ligament Cell Injury Through the miR‐527/TLR4 Axis

TL;DR
This retracted study claimed that reducing a specific circular RNA (circ_0087199) helps protect periodontal ligament cells from damage caused by bacteria, but the results are considered unreliable.
Contribution
The paper proposed a novel mechanism involving circ_0087199 and miR-527/TLR4 in periodontal cell injury, but it was retracted due to lack of reproducibility.
Findings
The study claimed circ_0087199 depletion reduces cell injury caused by lipopolysaccharides.
It suggested miR-527 and TLR4 are involved in the protective mechanism.
However, the results were deemed unreliable due to unclear methodology and unavailability of data.
