Prostate cancer is the second most common cancer in men worldwide. Despite medical advances in recent years, this type of tumour is still responsible for one in eight male cancer deaths in Austria alone. An international research team led by MedUni Vienna has now investigated a new strategy for the development of treatment options that not only slow tumour growth, but also stimulate the immune system to combat tumour cells. The results of the study have just been published in the top journal "Molecular Cancer".
Duke-NUS scientists investigated how an inherited genetic variation common among East Asians contributes to drug resistance in cancer cells, driving more aggressive cancer growth. The team trialled a precision therapy for this group by blocking the action of a protein called MCL-1, successfully killing many of the cancer cells in laboratory studies.
Using the established cancer cell databases GDSC, CTRP and COSMIC, researchers developed a combined score of the 36 genes most linked to drug resistance. This polygenic score showed superior correlation with relative resistance to various anti-cancer drugs compared to existing polygenic score, and it predicted the expression of genes linked to breast cancer resistance against tamoxifen.
Study results showed the highest detectable concentrations of heavy metals were lead, barium and chromium. All samples except for lead had less than or the same levels expected for an urban area.The median levels of lead detected in seven samples from play areas (400 mg/kg) and three samples from residential areas (1200 mg/kg) were four times the levels for Texas overall. And these likely were underestimated because they did not account for lead-based paint or automotive fuel.
Xiaoguang Dong, assistant professor of mechanical engineering, is leading a team of researchers that has developed a system of artificial cilia capable of monitoring mucus conditions in human airways to better detect infection, airway obstruction, or the severity of diseases like Cystic Fibrosis (CF), Chronic Obstructive Pulmonary Diseases (COPD) and lung cancer.
A new USC study has found evidence that targeting CD47, a protein that is part of the innate immune system, could be a key step in fighting colorectal cancer. It is one of the first indications that targeting part of the innate immune system, combined with traditional immunotherapy drugs which work on the adaptive immune system, could be more effective in fighting colorectal cancer. In the present study researchers analyzed DNA and RNA from 14,287 colorectal cancer tumors, comparing tumors with higher levels of CD47 expression to those with lower levels. The researchers found that higher levels were linked to more aggressive tumors, more activated cancer pathways and more immune cells inside the tumor. The findings suggest that developing an immune checkpoint inhibitor drug that can block the activity of CD47 could improve outcomes for colon cancer patients, many of whom are not well served by existing immunotherapy drugs.
A research team from Oregon Health & Science University and Thayer School of Engineering at Dartmouth has developed an innovative fluorescence-guided surgery (FGS) technique using near-infrared (NIR) fluorophores to improve the identification of tumors and nerves during head and neck cancer surgeries. In a study utilizing a human HNSCC xenograft model, the researchers demonstrated that tumor-specific and nerve-specific fluorophores could be used simultaneously, allowing for real-time differentiation between cancerous tissues and critical nerves. This advancement has the potential to enhance surgical outcomes by enabling complete cancer resection while minimizing damage to surrounding healthy tissue, ultimately improving post-surgical quality of life for patients.
