Summary
Bisphosphonates (BP) are taken up by tumor-associated macrophages in primary tumors, according to new research. This finding advances understanding of bisphosphonates for potential adjuvant cancer therapy.
Area of Science:
- Oncology
- Pharmacology
- Immunology
Background:
- Bisphosphonates (BP) are established drugs for bone diseases.
- Their potential role in cancer therapy is an area of active investigation.
Purpose of the Study:
- To investigate the cellular uptake of bisphosphonates (BP) within primary tumors.
- To identify the specific cell types responsible for BP accumulation in the tumor microenvironment.
Main Methods:
- Utilized both animal models and human tumor samples.
- Employed techniques to visualize and quantify bisphosphonate localization within tumor tissues.
Main Results:
- Demonstrated significant uptake of bisphosphonates into the primary tumor.
- Identified tumor-associated macrophages (TAMs) as the predominant cell type internalizing bisphosphonates.
Conclusions:
- Tumor-associated macrophages are key cellular targets for bisphosphonate uptake in primary tumors.
- These findings support further research into bisphosphonates as a potential adjuvant therapy for cancer patients.

01:17Hormones and Bone Tissue
4.3K
The endocrine system produces and secretes hormones, which interact with the skeletal system. These hormones control bone growth, maintain bone once it is formed, and remodel it.
Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...

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.

01:40Bone Remodeling
41.3K
Bone remodeling is a continuous and balanced process of bone resorption by osteoclasts and bone formation by osteoblasts. In adults, it helps maintain bone mass and calcium homeostasis. While mechanical stress can stimulate turnover as part of the normal maintenance and reparative process, several hormones also regulate bone remodeling.

02:49Cancer Therapies
10.9K
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...

01:21Drug Distribution: Tissue Binding
4.4K
Upon entering the systemic circulation, drugs can distribute into the interstitial and intracellular fluid of various tissue cells. This distribution is facilitated by the binding of drugs to different cellular components within tissues, which may lead to drug accumulation in specific areas. Drugs bound to tissue components serve as reservoirs that release free drugs back into the system, prolonging the drug's overall action. However, this accumulation can also result in local toxicity.

01:15Drugs that Stabilize Microtubules
2.9K
Microtubules are dynamic structures that undergo cycles of catastrophe and rescue. The microtubules play a central role in cell division by forming the spindle apparatus for segregating the chromosomes. This makes them ideal targets for regulating dividing cells in tumors and malignant cancer cells. Microtubule stabilizing drugs help stabilize the microtubule formation and promote its polymerization. Paclitaxel was the first microtubule stabilizing agent used as anticancer drug in chemotherapy...
