Oesophagectomy is one of the most challenging surgical operations. Potential for morbidity and mortality is high. Minimally invasive techniques have been introduced in an attempt to reduce postoperative complications and recovery times. Debate continues over whether these techniques decrease

A 45-year-old man presented with an unclear rapidly growing, infiltrating tumour of the anterior chest wall. Biopsies were non-specific, serologies remained unremarkable. Shortly after admission the patient developed blurred vision. Ophthalmoscopical findings were typical of candida endophthalmitis.

During cancer cell invasion, faster moving cancer cells play a dominant role by invading further and metastasizing earlier. Despite the importance of these outlier cells, the source of heterogeneity in their migratory behavior remains poorly understood. Here, we show that anterior localization of

BACKGROUND Open transthoracic oesophagectomy is the standard treatment for infracarinal resectable oesophageal carcinomas, although it is associated with high mortality and morbidity rates of 2 to 10% and 30 to 50%, respectively, for both the abdominal and thoracic approaches. The worldwide

Exosomes are 40-100-nm-diameter nanovesicles of endocytic origin that are released from diverse cell types. To better understand the biological role of exosomes and to avoid confounding data arising from proteinaceous contaminants, it is important to work with highly purified material. Here, we

Since the identification of R-Ras, which is the first Ras-related GTPase isolated based on sequence similarity to the classical RAS oncogene, more than 160 members of the Ras superfamily of GTPases have been identified and classified into the Ras, Rho, Rap, Rab, Ran, Arf, Rheb, RGK, Rad, Rit, and

Mutations in adenomatous polyposis coli (APC) disrupt regulation of Wnt signaling, mitosis, and the cytoskeleton. We describe a new role for APC in the transport of mitochondria. Silencing of wild-type APC by small interfering RNA caused mitochondria to redistribute from the cell periphery to the

Recent brain tumour research has shown abnormalities in gene expression as key features for almost all common brain tumours investigated. However, there is increasing evidence that epigenetic abnormalities are also crucial for tumorigenesis. Epigenetic abnormalities are heritable alterations

Mitochondrial dysfunction is involved in aging and multiple degenerative diseases, including intervertebral disc degeneration (IVDD) and osteoarthritis (OA). Thus, the maintenance of mitochondria homeostasis and function is important. Mitophagy, a process that selectively clears damaged or

Mitochondrial distribution is integrally related to cellular function. Highly polarized cells, such as neurons, likely depend on mitochondrial transport to maintain proper synaptic function and neurite plasticity. In some cases, mitochondrial transport is also required for cellular migration and
