Chronic morphine treatment attenuates cell growth of human BT474 breast cancer cells by rearrangement of the ErbB signalling network. [PDF]
, 2013 There is increasing evidence that opioid analgesics may interfere with tumour growth. It is currently thought that these effects are mediated by transactivation of receptor tyrosine kinase (RTK)-controlled ERK1/2 and Akt signalling.

Expression and Localization of Opioid Receptors in Male Germ Cells and the Implication for Mouse Spermatogenesis. [PDF]
PLoS ONE, 2016 The presence of endogenous opioid peptides in different testicular cell types has been extensively characterized and provides evidence for the participation of the opioid system in the regulation of testicular function.

Clinical opioids differentially induce co-internalization of μ- and δ-opioid receptors
Molecular Pain, 2018 Opioid receptors play an important role in mediating the spinal analgesia. The μ-opioid receptor is the major target of opioid drugs widely used in clinics.

The Use of Computational Approaches in the Discovery and Mechanism Study of Opioid Analgesics
Frontiers in Chemistry, 2020 Opioid receptors that belong to class A G protein-coupled receptors (GPCRs) are vital in pain control. In the past few years, published high-resolution crystal structures of opioid receptor laid a solid basis for both experimental and computational ...

GTPγS-Autoradiography for Studies of Opioid Receptor Functionality
, 2020 The opioid receptors have been an interesting target for the drug industry for decades. These receptors were pharmacologically characterized in the 1970s and several drugs and peptides have emerged over the years.

Historical Review: Opiate Addiction and Opioid Receptors
Cell Transplantation, 2019 Substance use disorders (SUDs), defined as a collection of symptoms including tolerance and withdrawal, are chronic illnesses characterized by relapse and remission. In the United States, billions of dollars have been lost due to SUDs.
