Targeted Cancer Therapies02:57

Targeted Cancer Therapies

7.4K
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...

Skin Cancer01:30

Skin Cancer

3.1K
Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.
Basal Cell Carcinoma (BCC): BCC is the most common type of skin cancer, accounting for about 80% of cases. It typically develops in...

Tumor Immunotherapy01:27

Tumor Immunotherapy

468
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.

Treatment Resistant Cancers02:56

Treatment Resistant Cancers

3.2K
Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...

Clinical Applications of Epidermal Stem Cells01:19

Clinical Applications of Epidermal Stem Cells

2.7K
Epidermal stem cells (EpiSCs) are mainly located at the basal layer of the epidermis. These cells repair minor injuries of the skin and replace dead skin cells. However, EpiSCs’ cannot heal severe wounds such as major burns or those from diabetes or hereditary disorders. In such cases, culturing the epidermal stem cells from the patient is possible and has yielded successful treatment options, such as laboratory-grown skin grafts. These grafts are synthesized using a patient’s own...

Renewal of Skin Epidermal Stem Cells01:12

Renewal of Skin Epidermal Stem Cells

2.5K
The skin is divided into epidermis, dermis, and hypodermis, the skin's outermost, middle, and inner layers. The human epidermal layer regularly undergoes renewal, where old, dead cells are replaced by new cells. Epidermal stem cells or EpiSCs divide and differentiate to restore the lost cells. For the renewal process, some EpiSCs continuously self-renew. In contrast, few others differentiate into transit-amplifying cells, which later form prickle or spinous cells, followed by granular...

Area of Science:

  • Biophysics
  • Computational Biology
  • Oncology

Background:

  • Distinguishing cancerous from healthy cells is crucial for effective cancer therapy.
  • Exploiting biophysical differences between cell types offers a novel therapeutic avenue.

Purpose of the Study:

  • To evaluate the hypothesis of selectively targeting skin cancer cells.
  • To investigate the potential of exploiting the spectral gap between healthy and cancerous skin cells.

Main Methods:

  • Utilized a viscoelastic dynamic model for analytical and numerical simulations.
  • Performed modal, harmonic, and transient analyses on simulated cell properties.
  • Predicted cell mechanical properties based on nucleus-to-cytoplasm ratio changes during neoplastic transformation.

Main Results:

  • Identified an approximate frequency difference of 50-100 KHz between healthy and cancerous skin cells.
  • Transient analysis showed cancer cells' vibration amplitude grew 10 times faster than healthy cells.

Conclusions:

  • Cancer cells exhibit higher susceptibility to resonance with tuned ultrasound frequencies.
  • Highlights the need for advanced dynamic models and experimental validation for ultrasound-based cancer targeting.
