Long-patch Base Excision Repair01:02

Long-patch Base Excision Repair

8.0K
Since the discovery of the two BER pathways, there has been a debate about how a cell chooses one pathway over the other and the factors determining this selection. Numerous in vitro experiments have pointed out multiple determinants for the sub-pathway selection. These are:

Patch Clamp01:18

Patch Clamp

6.5K
Many fundamental cell functions such as muscle contraction and nerve transmission rely on the electrical signals produced by the movement of positively and negatively charged ions across the cell membrane. One competent method to record current flowing across the whole cell or single ion channel is the patch-clamp technique.
In this method, a glass micropipette containing electrolyte solution is tightly sealed against a small portion of the cell membrane. As a result, a patch of the cell...

Tumor Immunotherapy01:27

Tumor Immunotherapy

1.9K
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.

Tumor Progression02:07

Tumor Progression

7.4K
Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

The Tumor Microenvironment02:17

The Tumor Microenvironment

7.8K
Every normal cell or tissue is embedded in a complex local environment called stroma, consisting of different cell types, a basal membrane, and blood vessels. As normal cells mutate and develop into cancer cells, their local environment also changes to allow cancer progression. The tumor microenvironment (TME) consists of a complex cellular matrix of stromal cells and the developing tumor. The cross-talk between cancer cells and surrounding stromal cells is critical to disrupt normal tissue...

Cancer Stem Cells and Tumor Maintenance02:40

Cancer Stem Cells and Tumor Maintenance

6.0K
Early diagnosis and treatment can often cure cancer. However, even with treatment, residual cells called cancer stem cells (CSC) might remain, often causing tumor recurrence. These cancer stem cells possess the potential for self-renewal and multi-lineage differentiation and are often responsible for the therapeutic resistance displayed in most cancers.
Cancer stem cells are thought to originate from tissue-specific normal stem cells or progenitor cells. The normal stem cells usually reside in...

Summary

Standard treatments for common skin issues did not resolve this patient's persistent rash. Repeated skin biopsies eventually identified a rare underlying condition, highlighting the need for thorough diagnostic evaluation.

Area of Science:

  • Dermatology
  • Pathology

Background:

  • Persistent skin eruptions can be challenging to diagnose and manage.
  • Empiric treatment strategies are often employed for common dermatological conditions.

Observation:

  • A patient presented with a longstanding skin eruption that proved refractory to initial empiric therapies.
  • Multiple serial biopsies were performed to investigate the persistent dermatological issue.

Findings:

  • The serial biopsies ultimately led to the identification of an uncommon diagnosis.
  • This case underscores the importance of considering rare conditions when standard treatments fail.

Implications:

  • Diagnostic delays can occur with uncommon skin diseases.
  • A high index of suspicion and advanced diagnostic techniques like serial biopsies are crucial for diagnosing rare dermatological conditions.
