Summary
Lysosomes regulate DNA replication by controlling nucleotide synthesis and degradation. Targeting lysosome function offers new therapeutic strategies for diseases like cancer.
Area of Science:
- Cell Biology
- Molecular Biology
- Genetics
Background:
- Lysosomes are key organelles for cellular recycling and metabolic regulation.
- They maintain energy homeostasis and supply substrates for DNA replication.
- Replication stress from nucleotide imbalance threatens genome integrity.
Purpose of the Study:
- To review the interplay between lysosomal function and DNA replication.
- To explore the roles of nucleic acid degradation and nucleotide biosynthesis.
- To discuss therapeutic exploitation of these mechanisms.
Main Methods:
- Literature review of lysosome function in DNA replication.
- Analysis of nucleotide metabolism and lysosomal pathways.
- Examination of therapeutic targets related to lysosomes and DNA synthesis.
Main Results:
- Lysosomes, via mTORC1, are crucial for purine and pyrimidine synthesis.
- Lysosomal pathways impact DNA replication fidelity and genome stability.
- Targeting lysosomal function presents therapeutic opportunities.
Conclusions:
- Lysosomal activities are integral to DNA replication and cellular health.
- Dysregulation of lysosome-nucleotide-DNA replication links to pathologies.
- Modulating lysosome function is a promising therapeutic strategy, particularly in oncology.

Translesion DNA Polymerases
10.4K
Translesion (TLS) polymerases rescue stalled DNA polymerases at sites of damaged bases by replacing the replicative polymerase and installing a nucleotide across the damaged site. Doing so, TLS allows additional time for the cell to repair the damage before resuming regular DNA replication.
TLS polymerases are found in all three domains of life - archaea, bacteria, and eukaryotes. Of the different classes of TLS polymerases, members of the Y family are fitted with specialized structures that...

Replication in Eukaryotes
15.7K
In eukaryotic cells, DNA replication is highly conserved and tightly regulated. Multiple linear chromosomes must be duplicated with high fidelity before cell division, so there are many proteins that fulfill specialized roles in the replication process. Replication occurs in three phases: initiation, elongation, and termination, and ends with two complete sets of chromosomes in the nucleus.

The DNA Replication Fork
38.4K
An organism’s genome needs to be duplicated in an efficient and error-free manner for its growth and survival. The replication fork is a Y-shaped active region where two strands of DNA are separated and replicated continuously. The coupling of DNA unzipping and complementary strand synthesis is a characteristic feature of a replication fork. Organisms with small circular DNA, such as E. coli, often have a single origin of replication; therefore, they have only two replication...

Lysosomes
22.9K
Lysosomes are membrane-enclosed spherical sacs derived from the Golgi apparatus. The most important function of the lysosome is degrading macromolecules and biological polymers that are released during membrane trafficking events such as the secretory, endocytic, autophagic, and phagocytic pathways. The degradation is carried out by several hydrolytic enzymes active in an acidic environment of the lysosomal lumen. These acid hydrolases are involved in cellular processes such as cell signaling,...
