Synthetic lethality exploits cancer cell genetic weaknesses to create targeted therapies, overcoming drug resistance in personalized medicine. This approach investigates key targets like PARP and PD-1 for novel oncology treatments.

Area of Science:

  • Oncology
  • Genetics
  • Pharmacology

Background:

  • Personalized medicine aims to move beyond one-size-fits-all treatments.
  • Acquired resistance to cancer therapies is a significant clinical challenge.
  • Synthetic lethality offers a strategy to target cancer cells by exploiting their genetic vulnerabilities.

Purpose of the Study:

  • To highlight key targets in synthetic lethality for cancer treatment.
  • To discuss medicinal chemistry efforts targeting these synthetic lethal vulnerabilities.
  • To explore the challenges and future directions in this field.

Main Methods:

  • Review of current synthetic lethality targets (PARP, ATR, ATM, DNA-PKcs, WEE1, CDK12, RAD51, RAD52, PD-1).
  • Discussion of medicinal chemistry programs and drug discovery approaches.
  • Analysis of challenges and future prospects in synthetic lethality research.

Main Results:

Lethal Alleles

Agouti: A Lethal Allele
Lucien Cuénot discovered lethal alleles in 1905 while studying the inheritance of coat color in mice. The agouti gene is responsible for the color of the coat in mice. This gene codes for an agouti-signaling protein, which is responsible for melanin distribution in mammals. The wild-type allele gives rise to gray-brown coat color in mice, while the mutant allele gives rise to yellow coat color. In addition to coat color, the agouti gene is associated with the yellow...

Combined Effects of Drugs: Synergism01:27

Combined Effects of Drugs: Synergism

Synergism is a useful mechanism where combining two or more drugs is more effective than each constituent used alone. Such combinations are also called supra-additive interactions. The drugs collectively enhance the final therapeutic effect by acting on different targets. Another advantage is that the low dose of each constituent drug is sufficient to achieve the desired effect. This helps reduce the duration of therapy and lower the adverse effects of these drugs.

Effects of Chemicals: Overview01:27

Effects of Chemicals: Overview

Drugs, encompassing various chemical compounds from natural sources, lab synthesis, or genetic engineering, elicit different biological responses in living organisms. Some of these responses are desirable or therapeutic, while others are undesirable. The primary goal of administering a drug is to achieve a therapeutic effect, that is, to address a specific disease or health condition. Any concurrent effects outside of this therapeutic outcome are considered undesirable. These undesirable...

Synthetic Biology

Synthetic biology is an interdisciplinary science that involves using principles from disciplines such as engineering, molecular biology, cell biology, and systems biology. It involves remodeling existing organisms from nature or constructing completely new synthetic organisms for applications such as protein or enzyme production, bioremediation, value-added macromolecule production, and the addition of desirable traits to crops, to name a few.

In-vitro Mutagenesis

To learn more about the function of a gene, researchers can observe what happens when the gene is inactivated or “knocked out,” by creating genetically engineered knockout animals. Knockout mice have been particularly useful as models for human diseases such as cancer, Parkinson’s disease, and diabetes.

Antidotes

Antidotes are medicinal substances used to counteract the harmful effects of toxins or drugs in the body. They function in various ways, each uniquely designed to combat specific toxic compounds.
Specific antidotes operate by inhibiting the enzymes that control biochemical pathways, reducing the production of harmful metabolites.
An example of an antidote is atropine, which counteracts the detrimental effects of cholinesterase inhibitors. It achieves this by deactivating muscarinic receptors,...
