Targeted Cancer Therapies

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...

Modified-Release Drug Delivery Systems: Site-Targeted

Modified-Release Drug Delivery Systems: Site-Targeted

Site-targeted drug delivery systems enhance therapeutic efficacy while minimizing systemic toxicity and treatment costs. Unlike conventional methods, these systems ensure precise drug delivery, improving bioavailability and reducing side effects. Targeted drug delivery is classified into three levels. First-order targeting directs drugs to the capillary beds of specific organs or tissues. Second-order targets specific cell types, such as tumor cells, using receptor-mediated interactions.

Key Elements for Plant Nutrition

Key Elements for Plant Nutrition

Like all living organisms, plants require organic and inorganic nutrients to survive, reproduce, grow and maintain homeostasis. To identify nutrients that are essential for plant functioning, researchers have leveraged a technique called hydroponics. In hydroponic culture systems, plants are grown—without soil—in water-based solutions containing nutrients. At least 17 nutrients have been identified as essential elements required by plants. Plants acquire these elements from the atmosphere, the...

Targets for Drug Action: Overview

Targets for Drug Action: Overview

Drugs target macromolecules to modify ongoing cellular processes. Primary drug targets include receptors, ion channels, transporters, and enzymes.
Receptors are either membrane-spanning or intracellular proteins, which upon binding a ligand, get activated and transmit the signal downstream to elicit a response. Drugs bind receptors, either mimicking the action of endogenous ligands or blocking the receptor activity to bring about a modified response. Nearly 35% of approved drugs target the G...

Target Cell Response to Hormones

Target Cell Response to Hormones

Hormones intricately bind to receptors on the surface or within target cells, initiating a cascade of cellular responses.
Notably, the cellular response can be regulated by altering the number of receptors expressed in the cell. For example, prolonged exposure to elevated hormone levels results in a gradual decline or down-regulation in the number of receptors for that specific hormone on the cell surface. Conversely, in response to low hormone levels, cells may use up-regulation, producing an...

Summary

Nutritargeting delivers specific nutrients to targeted tissues, enhancing efficacy and avoiding side effects associated with broad administration. This approach offers a promising solution for localized nutrient delivery and therapeutic interventions.

Area of Science:

Nutritional Science
Biochemistry
Pharmacology

Background:

Specific tissues accumulate micronutrients for specialized functions, like beta-carotene in skin for antioxidant protection.
Carotenoids (lutein, zeaxanthin) concentrate in the eye's macula lutea, offering protection against oxidative damage.
Vitamin C (ascorbate) accumulates in tissues like the adrenal gland and brain, performing crucial metabolic and antioxidant roles.

Purpose of the Study:

To introduce and define the concept of nutritargeting as a method for selective nutrient delivery.
To explore the rationale and potential benefits of targeting nutrients to specific tissues.
To address the limitations and potential side effects of conventional high-dose micronutrient administration.

Main Methods:

Reviewing existing knowledge on tissue-specific micronutrient accumulation and function.

Drawing analogies with established "drug targeting" principles.

Identifying potential delivery routes and carrier requirements for effective nutritargeting.

Main Results:

Demonstrated that micronutrient accumulation in tissues is often linked to specific metabolic functions, not just storage.
Highlighted the risks of systemic "flooding" with micronutrients, leading to potential side effects.
Showcased examples and developments indicating the feasibility of accumulating micronutrients in target tissues while sparing others.

Conclusions:

Nutritargeting offers a strategy to overcome challenges in conventional micronutrient delivery.
It enables precise delivery, potentially enhancing therapeutic outcomes and minimizing adverse effects.
Further development of "carriers" and delivery systems is crucial for realizing the full potential of nutritargeting.
