Summary
Aneuploidy, or chromosome number changes, is linked to lethal prostate cancer. This study found that more aneuploidy in tumors predicts a higher risk of aggressive disease, even in high-grade cancers.
Area of Science:
- Oncology
- Genetics
- Genomics
Background:
- Aneuploidy (chromosome gains/losses) is common in cancer but less so in prostate cancer.
- The role of numerical chromosome aberrations in prostate cancer progression is unclear.
- Understanding aneuploidy's impact is crucial for predicting lethal prostate cancer.
Purpose of the Study:
- To investigate the association between aneuploidy and lethal disease in prostate cancer.
- To develop a method for identifying chromosome-arm alterations from tumor transcriptomes.
Main Methods:
- Developed a whole-transcriptome profiling method to detect chromosome-arm gains/losses.
- Analyzed 333 primary prostate tumors using this method.
- Validated findings in two independent prospective cohorts (n=404) with long-term follow-up.
Main Results:
- Increased extent of tumor aneuploidy predicted a higher risk of lethal prostate cancer.
- Patients with ≥5 predicted chromosome-arm alterations had 5.3x higher odds of lethal cancer.
- Aneuploidy was associated with lethality, including in high-risk Gleason score 8-10 tumors.
Conclusions:
- Tumor aneuploidy plays a significant role in driving aggressive prostate cancer.
- Transcriptome-based aneuploidy prediction is a valuable tool for risk stratification.
- Findings highlight aneuploidy as a key factor in prostate cancer lethality.

03:03mTOR Signaling and Cancer Progression
4.7K
The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.

Agouti: A Lethal Allele
Lucien Cuénot discovered lethal alleles in 1905 while studying the inheritance of coat color in mice. The agouti gene is responsible for the color of the coat in mice. This gene codes for an agouti-signaling protein, which is responsible for melanin distribution in mammals. The wild-type allele gives rise to gray-brown coat color in mice, while the mutant allele gives rise to yellow coat color. In addition to coat color, the agouti gene is associated with the yellow...

01:37Energy to Drive Translocation
2.7K
Mitochondrial protein import is powered by two distinct energy sources: ATP hydrolysis and electrochemical potential across the inner membrane. Newly synthesized precursors are bound by cytosolic chaperones of the Hsp70 family, which guide them to the import receptors on the mitochondrial surface. Utilizing the energy of ATP hydrolysis, Hsp70 chaperones transfer these precursors to the TOM receptors on the mitochondrial outer membrane.

02:15M-Cdk Drives Transition Into Mitosis
6.4K
Checkpoints throughout the cell cycle serve as safeguards and gatekeepers, allowing the cell cycle to progress in favorable conditions and slow or halt it in problematic ones. This regulation is known as the cell cycle control system.
Cyclin-dependent kinases, or Cdks, work in concert with cyclins to control cell cycle transitions. M-Cdk, a complex of Cdk1 bound to M cyclin, is a well-known example of this coordinated control that drives the transition from the G2 to the M phase.

Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

01:27Drive-Reduction Theory: Push Theory of Motivation
1.2K
Clark Hull's drive-reduction theory, introduced in the 1940s and 1950s and often termed the "push theory" of motivation, provides a framework for understanding how biological and learned drives influence behavior. Hull suggested that motivation originates from the need to alleviate physiological tension caused by unmet biological necessities. The theory proposes that when a basic need, such as hunger or sleep, goes unfulfilled, it creates an internal imbalance. This imbalance, or...
