“MEMO1 (mediator of

ErbB2-driven cell motility 1) regulates HER2-dependent cell migration. Increased MEMO1 expression is associated with cancer aggressiveness. Here, we found that MEMO1 is also involved in breast carcinogenesis via regulating GSK1838705A mouse insulin-like growth factor-I receptor-dependent signaling events. We showed that MEMO1 binds to insulin receptor substrate 1, activates the downstream PI3K/Akt signaling pathway, leads to upregulation of Snail1 and thereby triggers the epithelial-mesenchymal transition (EMT) program. In addition, MEMO1 overexpression is accompanied by growth factor-independent proliferation, anchorage-independent growth in soft agar, and enhanced metastatic potential. Together, these findings suggest that MEMO1 acts as an oncogene and is a potential

therapeutic target for cancer treatment.”
“Histone deacetylase 6 (HDAC6) is a cytosolic enzyme that catalyzes deacetylation of several proteins. Acetylated tubulin has been recently identified as a physiological substrate of HDAC6. However in previous reports, all in vitro binding and enzymatic assays were accomplished with only partially purified protein samples. Therefore, it still remained unclear whether HDAC6 alone could interact with tubulin and catalyze deacetylation. In this study, both binding and enzymatic assays were conducted using recombinant-derived HDAC6 and purified alpha/beta tubulin to eliminate possible contamination. Salubrinal nmr The results clearly demonstrated that interaction between HDAC6 and tubulin is independent EGFR inhibitor of other proteins. In addition, HDAC6 can independently catalyze deacetylation of both tubulin dimer and microtubule polymer.”
“A young man affected from keratoconus was submitted to deep lamellar keratoplasty (DLK). The day after, the presence of pseudochamber between the donor and the recipient cornea was observed by the slit-lamp and the patient was submitted to the injection of an air bubble into the anterior chamber. Approximately

six days later, multiple, whitish patches mostly located in the centre of the lamellar interface were noticed. Medical treatment was started immediately but no improvement was observed and penetrating keratoplasty was performed.\n\nAlthough this organism has been described as a microbial pathogen in blepharitis, conjunctivitis, keratitis, canaliculitis, dacryocystitis, and endophthalmitis, to the best of our knowledge, this is the first case report of keratitis after DLK caused by Actinomyces species.”
“IntroductionTriple A syndrome is an autosomal recessive disease, characterized by esophageal achalasia, alacrima, and adrenal insufficiency, as well as involvement of the central, peripheral, and autonomic nervous systems. This disease mimics amyotrophic lateral sclerosis in some patients. The causative gene encodes ALADIN, a nuclear pore complex (NPC) component.
