Molecular biology is the study of biology at a molecular level. The field overlaps with other areas of biology and chemistry, particularly genetics and biochemistry. Molecular biology chiefly concerns itself with understanding the interactions between the various systems of a cell, including the interactions between DNA, RNA and protein biosynthesis as well as learning how these interactions are regulated.

Hematoxylin compounds can selectively kill CALR mutant cancer cells

Patients with myeloproliferative neoplasm (MPN), a group of malignant diseases of the bone marrow, often have a carcinogenic mutated form of the calreticulin gene (CALR).

Higher degrees of necrosis are inked to poor survival in brain cancer patients

White blood cells are part of many immune system responses in the human body. New research shows that a specific type of those cells may cause brain cancer tissues to die – but that's not good news, according to researchers at Penn State College of Medicine and Penn State Cancer Institute.
