As the principal investigator and senior author for the above-mentioned publication (Das et al., 2018, GENE REPORTS 11, 94–100), it has been brought to my attention that a portion of 2.4. Surgical procedure for OA induction in the Materials and Methods section in this publication contains inaccurate description. Hence, we are respectfully requesting to publish a corrigendum to replace the surgical procedure with proper description and references as below: 2.4 Surgical procedure for OA induction All the surgical operations were performed under a microscope in an aseptic setting. Mice were placed in a supine position and anesthetized with 1.5% isoflurane (Abbott Laboratories, North Chicago, IL, USA) in oxygen via a facemask at a rate of 1 L/min. The toe or tail pinch with toothed forceps was used to assess the depth of anesthesia, and flick responses were interpreted as inadequate anesthesia. After confirming adequate anesthesia, a 1 cm left knee incision was made with a #15 scalpel blade. The knee joint was identified from the tibia and femur; and the medial meniscotibial ligament was identified using anatomic landmarks. To induce partial medial meniscectomy (PMM), which destabilizes the ligaments, a microscalpel at a depth of 0.5 mm was used to remove meniscus at midline (Knights et al., 2012; Kroin; et al., 2016; Das et al., 2018). The skin incision will be then closed with 4-0 vicryl suture.
