The invention relates to a process for the production of ethanol, the process comprising fermenting of a carbon source composition with a recombinant yeast,

wherein the carbon source composition comprises at least glucose and arabinose; and
wherein the recombinant yeast comprises arabinose isomerase activity, ribulokinase activity, ribulose phosphate epimerase activity, glycerol uptake activity and glycerol conversion capacity; and
wherein the recombinant yeast further comprises a genetic modification leading to the reduction, downregulation, inhibition and/or elimination of the activity of a homologous protein with glycerol-efflux activity; and
wherein each of the glucose and the arabinose is converted into ethanol.

In addition, the invention relates to a recombinant yeast that can be used in such a process.

The present disclosure provides methods for the treatment of a subject having BRAF-mutated cancer cells comprising administering an effective amount of an eIF4E inhibitor, which may be optionally used in combination with other therapies, such as RAF inhibitors. Furthermore, BRAF mutational status can be used to select for patients that would clinically benefit from eIF4E inhibition, such as patient with BRAF-mutated cancer cells that are resistant to RAF kinase inhibitors.

Provided is a non-naturally occurring microorganism capable of producing cadaverine, wherein the microorganism is genetically modified to overexpress lysine decarboxylase and pyridoxal kinase. Also provided is a method for producing cadaverine by using such microorganism without adding external pyridoxal 5′-phosphate.

The present disclosure provides compositions and methods for making and using engineered phagocytic cells that express a chimeric antigen receptor having an enhanced phagocytic activity for immunotherapy in cancer or infection.

A nanoparticle (for example, quantum dot) serves as a substrate for immobilizing enzymes involved in consecutive reactions as a cascade. This results in a significant increase in the rate of catalysis as well as final product yield compared to non-immobilized enzymes.

Described herein is a method for producing a transgenic cell product wherein the gene of interest is operably linked to an inducible promoter other than AOX1. Production of the transgenic cell product is activated when the host cell is grown on a non-repressing carbon source for de-repressing the inducible promoter and an amount of an inducer compound selected from the group consisting of: formaldehyde; S-formylglutathione; S-hydroxymethyl glutathione; formic acid; an alkali metal salt of formic acid; and an alkaline earth metal salt of formic acid; sufficient to induce the inducible promoter is added to the host cell culture.

The invention relates to a metabolic enzyme-disrupted aerobic strain and a method for culturing the strain. The present invention provides, for example, a culture comprising a culture medium that has been cultured under an aerobic condition, wherein the culture medium contains an aerobe, wherein the aerobe has a disrupted gene encoding a metabolic enzyme of glycolysis selected from the group consisting of the metabolic enzymes of glycolysis except hexokinase, thereby suppressing metabolism from a carbon source (e.g., glucose) to the TCA cycle in the aerobe.

Provided are methods, prokaryotic host cells, expression vectors, and kits for the production of psilocybin or an intermediate or a side product thereof. Also provided are methods, prokaryotic host cells, expression vectors, and kits for the production of norbaeocystin. In certain embodiments, the prokaryotic host cell is selected from the group consisting of Escherichia coli, Corynebacterium glutamicum, Vibrio natriegens, Bacillus subtilis, Bacillus megaterium, Escherichia coli Nissle 1917, Clostridium acetobutlyicum, Streptomyces coelicolor, Lactococcus lactis, Pseudomonas putida, Streptomyces clavuligerus, and Streptomyces venezuelae.

Novel gene deletions and translocations involving chromosome 2 resulting in fusion proteins combining part of Anaplastic Lymphoma Kinase (ALK) kinase with part of a secondary protein have been identified herein in human solid tumors, e.g. non-small cell lung carcinoma (NSCLC). Secondary proteins include Echinoderm Microtubule-Associated Protein-Like 4 (EML-4) and TRK-Fusion Gene (TFG). The EML4-ALK fusion protein, which retains ALK tyrosine kinase activity, was confirmed to drive the proliferation and survival of NSCLC characterized by this mutation. The invention therefore provides, in part, isolated polynucleotides and vectors encoding the disclosed mutant ALK kinase polypeptides, probes for detecting it, isolated mutant polypeptides, recombinant polypeptides, and reagents for detecting the fusion and truncated polypeptides. The disclosed identification of this new fusion protein enables methods for screening for compounds that inhibit the proteins, and methods for inhibiting the progression of a cancer characterized by the mutant polynucleotides or polypeptides.

This present disclosure provides adeno-associated viral vectors, recombinant adeno-associated vims (rAAV), and methods of their use in gene therapy for treating CDKL5 deficiency disorder (CDD). Also provided are pharmaceutical compositions comprising an rAAV of the invention and a pharmaceutically acceptable carrier or excipient. These pharmaceutical compositions may be useful in gene therapy for the treatment of CDD caused by mutations in CDKL.
