Abstract:
Among cell death regulators, members of the Bcl-2 family are of interest because they are highly conserved across species and represent promising targets for anticancer therapy. This family and its associated proteins include more than 25 members, with either anti- or proapoptotic functions. Although the overall regulation of apoptosis by Bcl-2 family proteins is now well understood, targeted therapy requires careful consideration of individual members of the family and their crosstalk. One of the most studied representatives of the Bcl-2 family is antiapoptotic Mcl-1. After 25 years of investigations, a large amount of data regarding Mcl-1's regulation and functions has been compiled. In this review, we summarize current knowledge about Mcl-1, focusing on molecular aspects relevant to Mcl-1-targeted therapies.
Insights
Members of the B-cell lymphoma 2 (Bcl-2) family, particularly Mcl-1, are key regulators of cell death and promising anticancer targets. This review focuses on Mcl-1
Area of Science:
- Molecular Biology
- Cell Biology
- Biochemistry
Background:
- The B-cell lymphoma 2 (Bcl-2) family comprises over 25 proteins regulating apoptosis, with conserved functions across species.
- Members exhibit either anti-apoptotic or pro-apoptotic roles, making them crucial in cell death pathways.
- While general apoptosis regulation by Bcl-2 proteins is understood, targeted anticancer therapies require detailed knowledge of individual members and their interactions.
Purpose of the Study:
- To review current knowledge on Mcl-1, an antiapoptotic member of the Bcl-2 family.
- To focus on the molecular aspects of Mcl-1 relevant for developing targeted anticancer therapies.
- To consolidate 25 years of research on Mcl-1 regulation and function.
Main Methods:
- Literature review and synthesis of existing research on Mcl-1.
- Analysis of molecular mechanisms governing Mcl-1 regulation and function.
- Compilation of data relevant to Mcl-1-targeted therapeutic strategies.
Main Results:
- Mcl-1 is a highly studied antiapoptotic protein within the Bcl-2 family.
- Extensive data exists on Mcl-1's regulation and diverse functions.
- Understanding Mcl-1's molecular intricacies is vital for effective anticancer drug development.
Conclusions:
- Mcl-1 is a significant focus in cancer therapy research due to its role in apoptosis.
- Targeted therapies against Mcl-1 require a deep understanding of its molecular biology.
- Further research into Mcl-1's crosstalk with other family members will refine therapeutic strategies.

Cancer Therapies
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
