Scientists have developed a technique to map the circuitry underlying fundamental life processes, shedding light on diseases such as cancer. The study reveals a circular network of regulators regulating regulators controlling the cell cycle, providing new insights into cellular processes and potential therapeutic targets.
Scientists at UIC found that increasing FoxM1B gene expression restored liver cell growth rates and division activity in aged mice, potentially treating aging-related diseases such as cancer and Alzheimer's. This breakthrough could lead to new therapies for the elderly using gene therapy.
Researchers at Massachusetts General Hospital have found a gene called archipelago, or ago, involved in destroying the protein cyclin E. This regulation is crucial for cell division, and irregularities may lead to uncontrolled growth and cancer.
Researchers used DNA-coated microchips to discover that flavopiridol works by broadly inhibiting messenger RNA molecules, which are responsible for carrying genetic information to cellular protein factories. This inhibition ultimately leads to a halt in the production of certain proteins, allowing normal cellular processes to continue.
Researchers have isolated a new version of a herpesvirus that kills cancer cells but spares normal tissue, dramatically reducing prostate cancer tumors in mice. The new virus contains an extra genetic mutation that enables more robust reproduction and prevents the cell from mounting a response to stop viral replication.
Scientists found that weakening cell death signal and blocking engulfment increases cell survival rates, with some cells surviving outright. This finding suggests modulating engulfment machinery could be an effective therapy for neurodegenerative diseases, stroke, and cancer.
Researchers discover bacterial toxin ST can slow down metastatic colorectal cancer tumor growth by targeting GCC receptor. GCC is a protein marker on cancer cells that allows scientists to detect if they have spread, and it can also be used as a diagnostic tool.
Researchers discovered a multi-layered protection mechanism in yeast cells that prevents duplicate genes from causing cancer. The system involves three overlapping controls requiring the reversal of multiple chemical processes before genes can be re-copied.
A UC Berkeley scientist proposes that chromosome reassortment, rather than genetic mutations, is the cause of cancer's tendency to develop drug resistance. This theory suggests aneuploid cells, with abnormal numbers of chromosomes, are more prone to producing drug-resistant cancer cells.
A laboratory study found that vitamin E concentrations did not interfere with the killing of cancer cells by radiation therapy. However, the study's limitations mean that the impact on real-world treatment outcomes is unclear.
A Duke University study reveals that long-term genetic instability in cancer cells can be induced by stresses beyond DNA damage, including nutrient starvation and heat. This persistent genetic instability may play a key role in carcinogenesis and could help explain the large number of mutations seen in cancer cells.
Researchers at Rutgers University have developed a new pharmaceutical 'smart bomb' that targets cancer cells using an improved prodrug delivery system. The system uses nitroreductase as the activating trigger, guaranteeing a direct hit on cancerous cells and minimizing damage to normal cells.

The study suggests that angiogenesis inhibitors might be useful at the earliest stages of tumor development to prevent recurrence and spread.
The study shows how chromosomes are distributed unevenly during cancer cell division, leading to genetic defects and abnormal growth. The researchers also discovered a breakage-fusion-bridge cycle that can amplify gene copies contributing to cancer growth.
Researchers at Yale Cancer Center identified two mechanisms to inhibit the Survivin gene's protective function, which can lead to cancer cell death. The study used molecular antagonists and showed promise in preclinical studies, paving the way for potential therapeutic applications.
Researchers discovered that green tea's EGCg compound inhibits an enzyme required for cancer cell growth and can kill cultured cancer cells. Drinking more than four cups of green tea a day may provide enough of the active compound to slow and prevent cancer cell growth.
A new study by University of Wisconsin-Madison biochemist Ron Raines found that a ribonuclease A protein in humans has the same cancer-fighting potential as a frog-derived protein. The finding opens a door to creating a new class of natural drugs aimed at fighting cancer without side effects.
Researchers found cancer cells self-destruct when glucose is cut off, suggesting a potent new way to fight cancer with few side effects. The discovery was made using a compound that disrupts glycolysis, the process that produces energy from sugar, and could be used in combination with existing treatments.
Researchers at Case Western Reserve University have discovered that epigallocatechin-3-gallate, a green tea compound, can induce programmed cell death in cancer cells without harming healthy cells. This finding offers new hope for cancer prevention and treatment, and may lead to the development of purified polyphenolic derivatives.
Researchers are developing a new approach to cancer treatment called adoptive immunotherapy, which uses tumour antigens to stimulate immune cells. Tumour antigens are identified and used to sensitize T cells, which then recognize and attack cancer cells.
Researchers have discovered compounds in the bark of the pawpaw tree that show preliminary success in fighting some drug-resistant cancers. The compounds, called Annonaceous acetogenins, preferentially kill multidrug-resistant cells by inhibiting ATP production, pulling the plug on their energy source.

Cancerous cells produce high amounts of free-radicals that promote uncontrolled cell growth; antioxidants and protein inhibitors can suppress this process, slowing down runaway cell division.
Researchers have identified an inactive gene that contributes to cancer development when it fails to work in harmony with the tumor-suppressing p53 gene. The findings suggest that the bax gene can act as a tumor suppresser, and its dysfunction may lead to increased cancer cell death and tumor growth.
