Summary
Targeted therapies for hematologic malignancies focus on molecular abnormalities. Advances in understanding the mixed lineage leukemia (MLL) gene
Area of Science:
- Oncology
- Molecular Biology
- Genetics
Background:
- Hematologic malignancies treatment is shifting towards targeted therapies.
- The mixed lineage leukemia (MLL) proto-oncogene is frequently rearranged in acute leukemias.
Purpose of the Study:
- To review advances in understanding MLL gene's role in leukemogenesis.
- To highlight the characterization of MLL complex proteins and downstream pathways.
Main Methods:
- Literature review of MLL gene rearrangements and associated proteins.
- Analysis of structure/function studies on MLL functional domains.
- Characterization of MLL-related transcriptional regulation and signaling pathways.
Main Results:
- Numerous MLL translocation partners and their functional domains have been identified.
- Key proteins within the MLL complex and its fusion partners are crucial for leukemia pathogenesis.
- Downstream mediators and collaborating signaling pathways in MLL-related leukemogenesis are elucidated.
Conclusions:
- Understanding MLL-related leukemogenesis is advancing.
- These insights form the basis for developing novel targeted therapeutic strategies.
- Future research aims to improve treatment outcomes for MLL-driven leukemias.

02:57Targeted Cancer Therapies
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.

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...
02:38Mitogens and the Cell Cycle
Mitogens and their receptors play a crucial role in controlling the progression of the cell cycle. However, the loss of mitogenic control over cell division leads to tumor formation. Therefore, mitogens and mitogen receptors play an important role in cancer research. For instance, the epidermal growth factor (EGF) - a type of mitogen and its transmembrane receptor (EGFR), decides the fate of the cell's proliferation. When EGF binds to EGFR, a member of the ErbB family of tyrosine kinase...
02:50Combination Therapies and Personalized Medicine
Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...
