Base Excision Repair

One of the common DNA damages is the chemical alteration of single bases by alkylation, oxidation, or deamination. The altered bases cause mispairing and strand breakage during replication. This type of damage causes minimal change to the DNA double helix structure and can be repaired by the base excision repair (BER) pathways. BER corrects damaged DNA sequences by removing the damaged base and restoring the original base sequence using the complementary strand as a template.
The first step of...

The eukaryotic nucleus is a double membrane-bound organelle that contains nearly all of the cell’s genetic material in the form of chromosomes. It is rightly called the “brain” of the cell as it shoulders the responsibility of responding to various physiological processes, stress, altered metabolic conditions, and other cellular signals. 
The nucleus contains many membrane-less subnuclear organelles or nuclear bodies, such as nucleoli, Cajal bodies, speckles,...

EDTA: Auxiliary Complexing Reagents

EDTA titrations are usually carried out in highly basic conditions, where the fully deprotonated form of EDTA, Y4−, actively complexes with the free metal ions in the solution. Several metal ions precipitate as hydrous oxide (hydroxides, oxides, or oxyhydroxides) under these conditions, lowering the concentration of free metal ions in the solution. For this reason, auxiliary complexing agents or ligands such as ammonia, tartrate, citrate, or triethanolamine are used in EDTA titrations to...

Area of Science:

  • Genomics
  • Bioinformatics
  • Cancer Research

Background:

  • PROGgene, a tool for studying gene prognostic implications in cancer, required improvements.
  • The initial version had limitations that prompted the development of a new version.

Purpose of the Study:

  • To present major enhancements in the PROGgeneV2 tool.
  • To improve the survival analysis capabilities for prognostic research in cancer.

Main Methods:

  • Expanded the repository of public cancer studies by nearly twofold.
  • Introduced new survival analysis functionalities for single genes, gene signatures, gene expression ratios, and curated signatures.
  • Enabled adjustment of survival analysis models for covariates.
  • Added the capability for users to upload and analyze their own datasets.

Main Results:

  • PROGgeneV2 supports survival analysis on single genes, multiple genes (signatures), gene expression ratios, and published signatures.
  • Users can now adjust survival models for covariates and search gene signatures by keywords.
  • The tool allows for the analysis of prognostic implications across various cancer types.
  • Users can upload and analyze custom datasets for gene survival analysis.

Conclusions:

  • PROGgeneV2 is a comprehensive survival analysis tool for the scientific community.
  • The tool facilitates hypothesis formulation and mechanistic study design in cancer research.
  • PROGgeneV2 is accessible at http://www.compbio.iupui.edu/proggene.
