Targeted Cancer Therapies02:57

Targeted Cancer Therapies

9.0K
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...

Targets for Drug Action: Overview

10.6K
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 Hormones01:22

Target Cell Response to Hormones

5.8K
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...

Pharmacogenomics: Identification of New Drug Targets

Advances in genomics have profoundly influenced drug discovery by increasing both the speed and accuracy of pharmaceutical development. Pharmacogenomics, which examines how genetic variation influences drug response, facilitates the identification of novel therapeutic targets and enables patient stratification for personalized treatment. These strategies contribute to improved drug efficacy, minimized adverse effects, and more efficient clinical trial design.Mapping genetic differences...

Modified-Release Drug Delivery Systems: Site-Targeted

18
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.

Site-Targeted Drug Delivery Systems: Polymeric Carriers

16
Polymeric carriers enhance targeted drug delivery by increasing efficacy while minimizing off-target effects. These carriers comprise a biodegradable polymeric backbone integrated with functional elements that enable targeting, improve physicochemical properties, and regulate drug release.Targeting MechanismsThe targeting ability of polymeric carriers is mediated by a homing device, which is a molecular recognition component designed to selectively bind to specific tissues or cells. Monoclonal...

Area of Science:

  • Urology
  • Radiology
  • Oncology

Background:

  • Conventional ultrasound-guided prostate biopsies have limitations, causing underdetection of significant prostate cancer (PCa) and overdetection of insignificant PCa.
  • Multiparametric MRI (mpMRI) offers superior localization of prostate tumors compared to ultrasound.

Purpose of the Study:

  • To review techniques for MRI-targeted prostate biopsies.
  • To discuss the clinical impact of these advanced biopsy methods on PCa diagnosis.

Main Methods:

  • Direct in-gantry biopsy of MRI-identified lesions.
  • Indirect biopsy using MRI-ultrasound fusion (visual or software-based).

Main Results:

  • MRI-targeted biopsies enhance the localization and detection of clinically significant prostate cancer.
  • Fusion techniques improve the accuracy of targeting suspicious lesions identified on MRI.

Conclusions:

  • MRI-targeted prostate biopsy techniques, including fusion imaging, represent an advancement over conventional methods.
  • These techniques hold significant potential for improving the accuracy and clinical utility of prostate cancer diagnosis.
