Delayed blockage of prostaglandin EP₄ receptors can reduce dedifferentiation, epithelial‐to‐mesenchymal transition and fibrosis following acute kidney injury

Mohamed Abouelkheir, Dalia A. Shabaan, Mohamed Awad Shahien

Clinical and Experimental Pharmacology and Physiology > 48 > 5 > 791 - 800

Dedifferentiation of tubular epithelial cells is involved in both regeneration and fibrosis following acute kidney injury (AKI). Prostaglandin E₂ receptor 4 (EP₄) antagonist can inhibit the dedifferentiation of renal tubular cells. The present study investigated whether the time of blockage of EP₄ receptors, using grapiprant, could affect the tubular regeneration or interstitial fibrosis in AKI. Cisplatin...

Indian Journal of Surgical Oncology > 2018 > 9 > 3 > 336-339

Supraclavicular nodal metastases of breast cancer are rare and occur in about 8% of newly diagnosed cases. It is rarely discussed in the literature that breast cancer was metastasizing to higher levels of the cervical nodes. We report a case of metastatic breast cancer to the deep cervical lymph nodes that caused stridor due to compression of the recurrent laryngeal nerve which was diagnosed by indirect...
