Summary
Researchers developed new DNA-based nanoprobes to detect aggressive prostate cancer phenotypes. These probes target specific cancer cell features in the tumor microenvironment, enabling precise diagnosis and targeted therapy.
Area of Science:
- Biomedical Engineering
- Nanotechnology
- Oncology
Background:
- Distinguishing indolent from aggressive prostate cancer is difficult despite diagnostic advances.
- Cancer cell phenotypes within the tumor microenvironment influence treatment resistance and disease progression.
Purpose of the Study:
- To develop phenotype-specific molecular probes for aggressive prostate cancer detection.
- To utilize a microenvironment-guided strategy for probe evolution.
- To enable precision diagnostics and targeted theranostics in prostate cancer.
Main Methods:
- Employing 3D tumor models to mimic cancer microenvironments for probe development.
- Functionalizing single-walled carbon nanotubes (SWCNTs) with single-stranded DNA (ssDNA) to create molecular probes.
- Utilizing second near-infrared (NIR-II) fluorescence imaging for non-invasive detection.
Main Results:
- Developed two probes (PC3D2 and PC2D2) with differential binding to aggressive prostate cancer cell phenotypes.
- Demonstrated non-invasive detection of aggressive phenotypes in heterogeneous tumors using NIR-II optical imaging.
- Showcased selective drug delivery to prostate cancer spheroids, enhancing therapeutic efficacy.
Conclusions:
- The microenvironment-guided strategy enables the creation of phenotype-specific nanoprobes.
- This approach advances precision diagnostics and theranostics for prostate cancer management.
- The methodology is generalizable for developing nanoprobes targeting diverse cancer phenotypes based on microenvironmental signatures.

Aggression
30.1K
Humans engage in aggression when they seek to cause harm or pain to another person. Aggression takes two forms depending on one’s motives: hostile or instrumental. Hostile aggression is motivated by feelings of anger with intent to cause pain; a fight in a bar with a stranger is an example of hostile aggression. In contrast, instrumental aggression is motivated by achieving a goal and does not necessarily involve intent to cause pain (Berkowitz, 1993); a contract killer who murders for...

The Evidence for Evolution
47.7K
Genetic variations accumulating within populations over generations give rise to biological evolution. Evolutionary changes can result in the formation of novel varieties and entire new species. These changes are responsible for the diverse forms of life inhabiting the planet. The evidence for evolution suggests that all living organisms descended from common ancestors.

Convergent Evolution
31.5K
Evolution shapes the features of organisms over time, ensuring that they are suited for the environments in which they live. Sometimes, selection pressure leads to the rise of similar but unrelated adaptations in organisms with no recent common ancestors, a process known as convergent evolution.

What is Natural Selection?
126.2K
Natural selection is an evolutionary process in which individuals with survival-promoting traits reproduce at higher rates. These favorable traits become more common within a population or species. Naturally selected traits initially arise via random genetic mutations. In order for selection to occur, there must be variation within a population, the trait controlling the variation must be heritable, and there must be an evolutionary advantage for variation in the trait.

Eukaryotic Evolution
40.3K
The endosymbiont theory is the most widely accepted theory of eukaryotic evolution; however, its progression is still somewhat debated. According to the nucleus-first hypothesis, the ancestral prokaryote first evolved a membrane to enclose DNA and form the nucleus. Conversely, the mitochondria-first hypothesis suggests that the nucleus was formed after endosymbiosis of mitochondria.

Synteny and Evolution
3.8K
John H. Renwick first coined the term “synteny” in 1971, which refers to the genes present on the same chromosomes, even if they are not genetically linked. The species with common ancestry tend to show conserved syntenic regions. Therefore, the concept of synteny is nowadays used to describe the evolutionary relationship between species.
