Summary
Most Burkitt lymphoma cases involve c-MYC gene changes. New research reveals that PI3K signaling and CyclinD3 mutations are key cooperating lesions driving lymphoma development in mice and humans.
Area of Science:
- Oncology
- Molecular Biology
- Genetics
Background:
- Chromosomal translocations activating c-MYC are hallmarks of Burkitt lymphoma.
- The specific genetic alterations cooperating with c-MYC in lymphomagenesis remain largely undefined.
Purpose of the Study:
- To identify cooperating genetic lesions driving lymphomagenesis in Burkitt lymphoma.
- To investigate the role of PI3K signaling and CyclinD3 in the context of c-MYC deregulation.
Main Methods:
- Analysis of genetic alterations in Burkitt lymphoma models and patient samples.
- Functional studies in mice to assess the impact of identified lesions on lymphomagenesis.
Main Results:
- Constitutive PI3K signaling was identified as a cooperating lesion.
- Mutations in CyclinD3 were found to cooperate with c-MYC deregulation.
- These cooperating lesions were observed in both mouse models and human Burkitt lymphoma.
Conclusions:
- Constitutive PI3K signaling and CyclinD3 mutations are critical cooperating genetic events in Burkitt lymphoma.
- Understanding these cooperating lesions offers potential therapeutic strategies for lymphoma treatment.

02:23Abnormal Proliferation
Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the daughter...
01:31Pulmonary Tuberculosis III
Tuberculosis (TB) is a contagious infection primarily affecting the lung parenchyma but which can also affect other body parts. TB can be classified based on disease development, presentation, and the affected anatomical site.
The first classification is based on the development of the disease, and it includes the following categories:

01:06Induced Pluripotent Stem Cells
Stem cells are undifferentiated cells that divide and produce different cell types. Ordinarily, cells that have differentiated into a specific cell type are terminally differentiated; however, scientists have found a way to reprogram these mature cells so that they dedifferentiate and return to an unspecialized, proliferative state. These cells are pluripotent like embryonic stem cells—able to produce all cell types—and are called induced pluripotent stem cells (iPSCs).

01:15Differentiation of Common Myeloid Progenitor Cells
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...
01:22PI3K/mTOR/AKT Signaling Pathway
The mammalian target of rapamycin (mTOR) is a serine/threonine kinase that regulates growth, proliferation, and cell survival in response to hormones, growth factors, or nutrient availability. This kinase exists in two structurally and functionally distinct forms: mTOR complex 1 (mTORC1) and mTOR complex 2 (mTORC2). The first form (mTORC1) is composed of a rapamycin-sensitive Raptor and proline-rich Akt substrate, PRAS40. In contrast, mTORC2 consists of a rapamycin-insensitive companion...
02:07Tumor Progression
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...
