LncRNA maternally expressed gene 3 (LncMEG3), which increases endoplasmic reticulum stress and inhibits cell proliferation [112], is considered to negatively correlate with VEGF, and in patients with diabetic retinopathy, while the serum levels of VEGF are upregulated, LncMEG3 are downregulated [113]. The gene discussed is VEGFA; the disease is diabetic retinopathy.
