Regulation of Metabolism01:19

Regulation of Metabolism

Cellular needs and conditions vary from cell to cell and change within individual cells over time. For example, the required enzymes and energetic demands of stomach cells are different from those of fat storage cells, skin cells, blood cells, and nerve cells. Furthermore, a digestive cell works much harder to process and break down nutrients during the time that closely follows a meal compared with many hours after a meal. As these cellular demands and conditions vary, so do the amounts and...
Cancer Therapies02:49

Cancer Therapies

Cancer therapies are various modes of treatment, such as surgery, radiation therapy, and chemotherapy that are administered to cancer patients.
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...

Tumor Immunotherapy01:27

Tumor Immunotherapy

Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.
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...

Area of Science:

  • Endocrinology
  • Bone Biology
  • Pharmacology

Background:

  • Intermittent parathyroid hormone (PTH) therapy has shown significant clinical benefits for osteoporosis, initiating a new category of skeletal anabolic agents.
  • Recombinant human parathyroid hormone (rhPTH) (1-34) was the first FDA-approved anabolic therapy for osteoporosis, though its administration requires subcutaneous injection.
  • Limitations in delivery methods have spurred the development of alternative systems like transdermal and oral preparations.

Purpose of the Study:

  • To review the advancements in anabolic therapies for osteoporosis.
  • To discuss novel delivery systems for existing anabolic agents.
  • To introduce emerging anabolic agents targeting bone formation.

Main Methods:

  • Literature review of clinical trials and preclinical studies.
  • Analysis of drug delivery system innovations.
  • Exploration of novel molecular targets in bone metabolism.

Main Results:

  • The development of transdermal and oral delivery systems for rhPTH (1-34) aims to enhance patient compliance and convenience.
  • Emerging anabolic therapies include monoclonal antibodies targeting sclerostin, a key inhibitor of osteoblastogenesis.
  • Bone morphogenetic proteins and parathyroid hormone-related protein (PTHrP) are also being investigated as potential osteoporosis treatments.

Conclusions:

  • Newer anabolic therapies and improved drug delivery systems are expanding treatment options for osteoporosis.
  • Targeting pathways like sclerostin inhibition and utilizing bone morphogenetic proteins represent promising avenues for future osteoporosis management.
  • Continued innovation in anabolic agents and delivery methods is crucial for improving skeletal health and managing osteoporosis effectively.
