Pan-Cancer Study Reveals Extrachromosomal DNA Frequency

Extrachromosomal circular DNA (eccDNA) are circular DNA found in human, plant and animal cells in addition to chromosomal DNA. eccDNA originate from chromosomal DNA and can be from 50 base pairs to several mega-base pairs in length and encode regulatory elements and several full genes. More...

Cancer-Associated T Cell Receptors Evaluated for Malignancy Detection

A key goal in oncology is diagnosing cancer early, when it is more treatable. Despite decades of progress, early diagnosis of asymptomatic patients remains a major challenge. Most methods for this involve detecting cancer cells, but a different approach, focused on the body’s immune response. More...

Single-Cell Analysis Provides New Insights into Mitochondrial Diseases

Mitochondrial diseases result from failure of mitochondria, specialized compartments within cells that contain their own DNA and produce the energy needed to sustain life. Some of the most challenging mitochondrial disorders arise from mutations in mitochondrial DNA (mtDNA), a high-copy-number genome that is maternally inherited. More...

Prostate Cancer Identified By Profiling Immune Cell Subsets

With an estimated 1.8 million new cases in 2018 alone, prostate cancer is the fourth most common cancer in the world. Diagnosing the disease early increases the chances of survival, but this cancer remains difficult to detect. More...

Circulating tumor DNA Test Predicts Immunotherapy Response

 Immunotherapy is a type of cancer treatment that helps the immune system fight cancer. Although some cancer patients derive dramatic and sustained benefit from immunotherapy, most cancer patients do not. More...

Renal Expression of Immunomodulators in Diabetic Nephropathy

Diabetic nephropathy (DN) is a chronic microvascular complication that affects about 20% to 30% of patients with type 2 diabetes mellitus (T2DM). It is considered the leading cause of end-stage renal failure requiring renal replacement therapy. More...
