Hypoxia‑induced autophagy is inhibited by PADI4 knockdown, which promotes apoptosis of fibroblast‑like synoviocytes in rheumatoid arthritis.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Impaired apoptosis of rheumatoid arthritis (RA)‑fibroblast‑like synoviocytes (FLS) is pivotal in the process of RA. Peptidyl arginine deiminase type IV (PADI4) is associated with autoantibody regulation via histone citrullination in RA. The present study aimed to investigate the role of PADI4 in the apoptosis of RA‑FLS. FLS were isolated from patients with RA and a rat model. The effects of PADI4 on RA‑FLS were investigated in vitro and in vivo. Hypoxia‑induced autophagy was induced by 1% O2 and was detected by immunohistochemical and immunofluorescence analysis; in addition, apoptosis was detected by flow cytometry. RA‑FLS obtained from RA rat model exhibited significant proliferation under severe hypoxia conditions. Hypoxia also significantly induced autophagy and elevated the expression of PADI4. Subsequently, short hairpin RNA‑mediated PADI4 knockdown was demonstrated to significantly inhibit hypoxia‑induced autophagy and promote apoptosis in RA‑FLS. The results of these in vitro and in vivo studies suggested that PADI4 may be closely associated with hypoxia‑induced autophagy, and the inhibition of hypoxia‑induced autophagy by PADI4 knockdown may contribute to an increase in the apoptosis of RA‑FLS.
