Diabetic nephropathy (DN), also known as diabetic kidney disease (DKD), is a drastic renal complication of type 1 and type 2 diabetes mellitus (DM). Poorly controlled DM over the years, may disrupt kidneys' blood vessels, leading to the hypertension (HTN) and DN onset. During DN, kidneys' waste filtering ability becomes disturbed. Being on a healthy lifestyle and controlling both DM and HTN are now the best proceedings to prevent or at least delay DN occurrence. Unfortunately, about one-fourth of diabetic individuals eventually experience the corresponding renal failure, and thus it is critical to discover effective diagnostic biomarkers and therapeutic strategies to combat DN. In the past few years, circular RNAs (circRNAs), as covalently closed endogenous non-coding RNAs (ncRNAs), are believed to affect DN pathogenesis in a positive manner. CircRNAs are able to impact different cellular processes and signaling pathways by targeting biological molecules or various molecular mechanisms. Still, as a key regulatory axis, circRNAs can select miRNAs as their molecular targets, in which they are considered as miRNA sponges. In this way, circRNA-induced suppression of particular miRNAs may prevent from DN progression or promotes the DN elimination. Since the expression of circRNAs has also been reported to be increased in DN-associated cells and tissues, they can be employed as either diagnostic biomarkers or therapeutic targets.

Hippocampal Up-Regulation of Apolipoprotein D in a Rat Model of Maternal Hypo- and Hyperthyroidism: Implication of Oxidative Stress.

Thyroid disorders impair various functions of the hippocampus where thyroid hormone receptors are localized in the brain. Hyper and hypothyroidism are associated with large changes in brain oxidative stress. Apolipoprotein D (APOD) is a conserved glycoprotein that increased in response to oxidative stress in the brain and has been suggested function as an antioxidant in the brain. Thus, the goal of this work was to explore the effect of maternal hypo- and hyperthyroidism on the Apod expression in the pup's brain regarding changes in oxidative stress. For induction hypo and hyperthyroidism in adult female rats, 100 ppm propylthiouracil (PTU) and 8 ppm levothyroxine administrated 1 month before copulation to the week 3 after delivery in drinking water. The hippocampal region of rat pups was isolated and used for immunohistochemistry and quantitative RT-PCR on postnatal day (PND)5, PND10 and PND20. Results revealed that APOD over-expressed in both hypo- and hyperthyroid groups on PND5, PND10, and PND20. There was a proportional increase between the Apod expression and oxidative stress in the hyperthyroid group but not the hypothyroid in different days. Regarding the wide functions of thyroid hormones, oxidative stress does not suggest to be the only mechanism that involves Apod gene expression in thyroid disturbances.
