HER2 in Metastatic Colorectal Cancer
HER2 is an emerging biomarker in colorectal cancer (CRC). This oncogene plays an essential role in regulating cell proliferation, differentiation, migration, and, more in general, tumorigenesis and tumor progression. The most frequent types of HER2 alterations in CRC include gene amplification and missense mutations in 7–8% of CRC, often being mirrored by HER2 protein overexpression, representing founder events in solid tumors, including CRC.

New insights in Liver Regeneration
The physiological importance of the liver is demonstrated by its unique and essential ability to regenerate following extensive injuries affecting its function. By regenerating, the liver reacts to hepatic damage and thus enables homeostasis to be restored. The actors involved in the regenerative process are numerous and many of them are also pivotal players in both the immune and non-immune inflammatory process, that is observed in the early stages of hepatic regeneration. Balance of Th17/Treg is important in liver inflammatory process outcomes.

Bile Acids in the Liver and Gut Metabolism
Bile acids (BAs) represent heterogeneous amphipathic molecules that have both polar (water-soluble or hydrophilic) and apolar (water-insoluble or hydrophobic) parts, and therefore they can dissolve in water as well as in fat. The regulation of cholesterol homeostasis remains their main role in the host. The better water solubility in comparison with their precursor promotes cholesterol removal from the human body. The proper bile ratio of BAs and cholesterol prevents cholesterol precipitation and further formation of gallstones; therefore, the loss of BAs increases the risk of cholesterol stone development.

The Applications of Colonic Transendoscopic Enteral Tubing
The limitation of traditional delivery methods for fecal microbiota transplantation (FMT) gave birth to colonic transendoscopic enteral tubing (TET) to address the requirement of frequent FMTs. Colonic TET as a novel endoscopic intervention has received increasing attention in practice since 2015 in China. Emerging studies from multiple centers indicate that colonic TET is a promising, safe, and practical delivery method for microbial therapy and administering medication with high patient satisfaction.

DAO Activity in the Monitoring of Diverse Diseases
The serum level of diamine oxidase (DAO) reflects the integrity and maturation of the small intestinal mucosa. This measure is important in diagnosing various diseases, including chronic urticaria tachyphylaxis, multiple organ dysfunction syndrome, preterm abortion, and migraine.

Pathophysiology of Inflammatory Bowel Disease
Inflammatory bowel disease (IBD) encompasses a group of heterogeneous diseases that entail chronic, relapsing gastrointestinal tract inflammation of inexactly known etiology and pathogenesis. IBD is clinically classified as Crohn’s disease (CD) or ulcerative colitis (UC) based on symptoms, disease location, and histopathological characteristics.

Multiple Sclerosis Therapies and Drug-Induced Liver Injury
Multiple sclerosis (MS) is a chronic demyelinating disease of the central nervous system and the association with other autoimmune diseases is well-documented. There are many therapeutic options for the treatment of MS. Most of the available drugs cause drug-induced liver injury (DILI) to variable extents with heterogeneous clinical and biological manifestations, including liver injury with or without signs of hypersensitivity and autoimmunity. The different disease-modifying therapies (DMTs) and immunomodulating treatments used in the management of MS include interferon beta (IFN-β), glatiramer acetate (GA), natalizumab, fingolimod, mitoxantrone, teriflunomide, dimethyl fumarate, alemtuzumab, daclizumab, and ocrelizumab. These drugs are largely available in the USA and Europe, but with some differences in indications.

Hepatocyte Growth Regulators
Researchers have studied whether growth factors, cytokines, hormones, neurotransmitters, and local hormones (autacoids) promote the proliferation of hepatic parenchymal cells (i.e., hepatocytes) using in vitro primary cultured hepatocytes. The indicators used for this purpose include changes in DNA synthesis activity, nuclear number, cell number, cell cycle, and gene expression. In addition, the intracellular signaling pathways from the plasma membrane receptors to the nucleus have been examined in detail for representative growth-promoting factors that have been found to promote DNA synthesis and cell proliferation of hepatocytes.

Vitamin D Metabolism in Celiac Disease
Celiac disease is a chronic autoimmune disorder involving the small intestine, characterized by villous atrophy, crypt hyperplasia and an increase in intraepithelial lymphocytes. Due to both calcium malabsorption and immune activation, a high prevalence of bone mass derangement is evident in this condition, regardless of the presence of overt malabsorption. In untreated patients, secondary hyperparathyroidism is responsible for the hyperconversion of 25-vitamin D into 1,25-vitamin D making mandatory the determination of serum levels of both vitamin metabolites to avoid a wrong diagnosis of vitamin D deficit. A gluten-free diet allows for a normalization of bone and mineral metabolism, reverting these abnormalities and raising some doubts on the need for vitamin supplementation in all the patients.

The Mediterranean Diet and Inflammatory Bowel Diseases
The Mediterranean diet is considered one of the healthiest dietary patterns worldwide, thanks to a combination of foods rich mainly in antioxidants and anti-inflammatory nutrients. Many studies have demonstrated a strong relationship between the Mediterranean diet and some chronic gastrointestinal diseases, such as inflammatory bowel diseases.
