Exocrine pancreatic insufficiency (EPI) is the inability to properly digest food due to a lack or reduction of digestive enzymes made by the pancreas.EPI can occur in humans and is prevalent in many conditions [1] such as cystic fibrosis, [2] Shwachman–Diamond syndrome, [3] different types of pancreatitis, [4] multiple types of diabetes mellitus (Type 1 and Type 2 diabetes), [5] advanced ...
Epigenetic mechanisms. In biology, epigenetics is the study of heritable traits, or a stable change of cell function, that happen without changes to the DNA sequence. [1] The Greek prefix epi-(ἐπι-"over, outside of, around") in epigenetics implies features that are "on top of" or "in addition to" the traditional (DNA sequence based) genetic mechanism of inheritance.

Exocrine pancreatic insufficiency (EPI) is the inability to properly digest food due to a lack of digestive enzymes made by the pancreas. EPI is found in humans affected by cystic fibrosis and Shwachman–Diamond syndrome. It is caused by a progressive loss of the pancreatic cells that make digestive enzymes.
The human epigenome, including DNA methylation and histone modification, is maintained through cell division (both mitosis and meiosis). [2] The epigenome is essential for normal development and cellular differentiation , enabling cells with the same genetic code to perform different functions.
In animals, numerous studies have shown that inherited epigenetic marks can increase susceptibility to disease. Transgenerational epigenetic influences are also suggested to contribute to disease, especially cancer, in humans. [70] Tumor methylation patterns in gene promoters have been shown to correlate positively with familial history of ...
Moreover, epi-marks are modifications of histone proteins. [9] Epigenetic marks are modifications of the methyl and acetyl groups that bind to DNA histones thereby changing how the proteins function and as a result, alter gene expression. [10] Epi-marks change how the histones function and as a result, influence the way genes are expressed. [1]

Although epigenesis appears to be an obvious fact in today's genetic age, historically, creationist theories of life's origins hindered its acceptance. [2] However, during the late 18th century an extended and controversial debate among biologists finally led epigenesis to eclipse the long-established preformationist view.
