Cancer Therapies

10.5K
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...

Cancer

55.2K
Cancers arise due to mutations in genes involved in the regulation of cell division, which leads to unrestricted cell proliferation. Modern science and medicine have made great strides in the understanding and treatment of cancer, including eradicating cancer in some patients. However, there is still no cure for cancer. This is largely due to the fact that cancer is a large group of many diseases.

Area of Science:

  • Biomedical Engineering
  • Nanotechnology
  • Cancer Therapy

Background:

  • Anaerobic bacteria selectively colonize tumor hypoxic regions (THRs).
  • Tumor hypoxia is a key factor in cancer progression and treatment resistance.

Purpose of the Study:

  • To develop an anaerobe nanovesicle mimic for targeted cancer therapy.
  • To engineer a light-induced hypoxia-responsive system for simultaneous drug activation and vehicle dissociation.

Main Methods:

  • Construction of an anaerobe nanovesicle mimic.
  • Incorporation of a light-induced hypoxia-responsive modality.
  • In vitro and in vivo experiments to evaluate therapeutic efficacy.

Main Results:

  • The nanovesicle demonstrated selective activation in THRs and induced tumor hypoxia.
  • Simultaneous dissociation of vehicles and activation of bioreductive prodrugs were achieved.
  • Significant inhibition of tumor growth and induction of apoptotic cell death were observed.

Conclusions:

  • Anaerobe-inspired nanovesicles offer a novel strategy for stimuli-responsive drug delivery.
  • This bioinspired approach enhances synergistic therapeutic effects in cancer treatment.
  • The developed system shows potential for effective cancer therapy by targeting tumor hypoxia.
