Insights

This review explores how opioid systems influence cancer growth. Researchers identified opioid ligands and receptors in human tumors, suggesting their role in regulating neoplasia.

Area of Science:

  • Endocrinology
  • Oncology
  • Neuroscience

Background:

  • Opioid and somatostatin systems are key mammalian inhibitory pathways regulating hormone secretion and cell proliferation.
  • Opioids and their receptors are present in numerous human tumors and cancer cell lines.
  • Research since the 1980s investigates the role of endogenous opioid systems in normal and abnormal tissue growth.

Purpose of the Study:

  • To review recent findings on opioid ligands and receptors in human neoplasia.
  • To examine the mechanisms of opioid peptide action in carcinoma.
  • To discuss the involvement of opioids in tumor growth regulation.

Main Methods:

  • Literature review of studies published since the early 1980s.
  • Analysis of research identifying opioid ligands and receptors in various human cancers.
  • Synthesis of data on opioid peptide mechanisms and tumor growth regulation.

Main Results:

  • Opioid ligands and receptors are widely identified across diverse primary human tumors and cancer cell lines.
  • Endogenous opioid systems play a significant role in the growth of both normal and abnormal tissues.
  • Evidence suggests opioids are involved in the regulation of tumor progression and development.

Conclusions:

  • Opioid systems represent a critical area of study in oncology.
  • Understanding opioid involvement in cancer could lead to novel therapeutic strategies.
  • Further research into opioid peptide mechanisms in carcinoma is warranted.

Opioid Receptors: Overview01:22

Opioid Receptors: Overview

Opioid receptors, including the mu (μ, MOR), delta (δ, DOR), and kappa (κ, KOR) types, belong to the rhodopsin family of G protein-coupled receptors. These receptors are located throughout the central and peripheral nervous systems and in non-neuronal tissues such as macrophages and astrocytes. Opioid receptor ligands can be categorized into agonists or antagonists. Highly selective agonists include [d-Ala2, MePhe4, Gly(ol)5]-enkephalin or DAMGO for MOR, [D-Pen2, D-Pen5]-enkephalin or DPDPE for...

Opioid Analgesics: Synthetic and Semisynthetic Opioids

Synthetic and semisynthetic opioids are pivotal in pain management and tackling opioid addiction. Semisynthetic opioids, including morphinans (morphine derivatives), oxycodone, oxymorphone, hydrocodone, and hydromorphone, have improved pharmacokinetic profiles compared to morphine. Additionally, heroin and 6-MAM (6-Monoacetylmorphine) show better CNS penetration than morphine due to heightened lipid solubility. Hydromorphone, a potent opioid, undergoes hepatic metabolism to form the active...

Opioid Analgesics: Morphine and Other Natural Cogeners

Opioids are a class of drugs that mimic endogenous opioid peptides and act on opioid receptors, and help in pain relief. These compounds are classified as natural, synthetic, or semi-synthetic. Natural opioids, like morphine, codeine, and thebaine, are derived from the opium poppy plant (Papaver somniferum or Papaver album) and are termed opiates. Synthetic opioids are artificial, while semi-synthetic opioids combine natural and synthetic compounds. Morphine, a prototypical opioid, possesses a...
Analgesia and Pain Management01:25

Analgesia and Pain Management

Pain is critical to various clinical pathologies, provoking an urgent need for effective management. Pain, whether acute or chronic, is a complex neurochemical process. Its alleviation depends on the type, with nonopioid analgesics effective for mild to moderate pain, such as musculoskeletal or inflammatory pain, while neuropathic pain responds best to anticonvulsants, tricyclic antidepressants, or serotonin/norepinephrine reuptake inhibitors. For severe acute or chronic pain, opioids may be...
Metastasis02:30

Metastasis

Metastasis is the spread of cancer cells from the original site to distant locations in the body. Cancer cells can spread via blood vessels (hematogenous) as well as lymph vessels in the body.
Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...
Targeted Cancer Therapies02:57

Targeted Cancer Therapies

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against specific...
