Tumor Progression02:07

Tumor Progression

6.2K
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...

Differentiation of Common Myeloid Progenitor Cells

3.1K
Common myeloid progenitors (CMPs) are oligopotent cells that can differentiate into granulocytes and macrophages. Granulocytes and macrophages are essential for protecting the body against bacterial, viral, or fungal infections. They migrate from the bone marrow into the circulating blood to reach specific tissue sites where they differentiate and help in immune surveillance. However, they survive only for a few days and must be continuously made available to the organism to maintain a robust...

Hybridoma Technology01:31

Hybridoma Technology

13.2K
Hybridoma technology is used for the large-scale production of monoclonal antibodies. Monoclonal antibodies bind to only a single antigenic determinant or epitope. Such antibodies are used in research, diagnostics, and disease therapy. The hybridoma technology established in 1975 by Georges Köhler and Cesar Milstein was awarded the Nobel Prize in Medicine in 1984 for revolutionizing research and therapy.

Cells of the Adaptive Immune Response01:23

Cells of the Adaptive Immune Response

6.9K
The T and B lymphocytes of the adaptive immune system develop from common lymphoid progenitor cells in the bone marrow. These progenitors give rise to precursors that eventually develop into both T and B lymphocytes. As these precursors mature, they gain the ability to detect and respond to foreign antigens in the body, a process known as immunocompetence. Additionally, these precursors acquire self-tolerance, a process that ensures they do not react to self-antigens. This intricate system...

Multiple Sclerosis l: Introduction

20
Multiple sclerosis is a chronic autoimmune disease of the central nervous system (CNS) that affects the brain, spinal cord, and optic nerves. It is an inflammatory demyelinating disorder and a leading cause of neurological disability in young adults.EpidemiologyMS commonly begins between 20 and 40 years of age and is twice as common in women. Its exact cause remains unclear, but genetic susceptibility contributes, with higher risk in first-degree relatives and identical twins. A greater...

Huntington Disease l: Introduction01:21

Huntington Disease l: Introduction

110
Huntington disease or HD is a progressive, fatal neurodegenerative disorder inherited in an autosomal dominant pattern.PathophysiologyIt is caused by expansion of the CAG trinucleotide repeat in the HTT gene on chromosome 4 (4p16.3), producing an abnormal huntingtin protein with an expanded polyglutamine tract. This misfolded protein disrupts cellular function, leading to neuronal death. Normal alleles have ≤26 repeats, 27–35 are intermediate (risk of expansion), 36–39 show...

Summary
This summary is machine-generated.

Multiple myeloma consistently follows precursor states like monoclonal gammopathy of undetermined significance (MGUS) and smoldering myeloma. New biomarkers are needed to predict progression and develop targeted therapies for these early stages.

Area of Science:

  • Hematology
  • Oncology
  • Molecular Diagnostics

Background:

  • Multiple myeloma diagnosis relies on clinical manifestations (hypercalcemia, renal failure, anemia, bone lesions).
  • Monoclonal gammopathy of undetermined significance (MGUS) and smoldering myeloma are recognized precursor states.
  • Current risk stratification for precursor states uses clinical markers.

Observation:

  • MGUS and smoldering myeloma are diagnosed via laboratory abnormalities.
  • Existing clinical markers aid in risk stratification and patient counseling.
  • There is a lack of biomarkers and molecular imaging for high-risk progression identification.

Findings:

  • Biomarkers are needed to understand the transformation mechanism to multiple myeloma.
  • Molecular imaging can help identify high-risk disease biology.
  • Current diagnostic methods for precursor states lack predictive power for progression.

Implications:

  • Development of novel biomarkers and molecular imaging is crucial.
  • Personalized management strategies for MGUS and smoldering myeloma require improvement.
  • Early treatment strategies may delay or prevent multiple myeloma development.
