Restoration of microRNA-29c in type I endometrioid cancer reduced endometrial cancer cell growth.

Endometrial cancer is the most common gynaecological cancer worldwide, and the prognosis of patients with advanced disease remains poor. MicroRNAs (miRs) are dysregulated in endometrial cancer. miRs-29-a, -b and -c expression levels are downregulated in endometrial cancer; however, a specific role for miR-29c and its target genes remain to be elucidated.

Galectin-7 is elevated in endometrioid (type I) endometrial cancer and promotes cell migration.

Endometrial cancer (EC) is the most commonly diagnosed gynecological malignancy in Australian women. Notably, its incidence and mortality rate is increasing. Despite this, there are limited treatment options for EC.

Exploration of broadly neutralizing antibody fragments produced in bacteria for the control of HIV.

While broadly neutralizing antibodies (bnAbs) are a promising preventative and therapeutic tool for HIV infection, production is difficult and expensive. Production of antibody-like fragments in bacterial cytoplasm provides a cheaper alternative. This work explored the transplantation of the complementarity determining regions of the anti-HIV bnAbs PGT121 and 10E8 onto a single-chain variable fragment (scFv) scaffold, previously discovered through a novel screening platform.

Bacterial cytoplasmic display platform Retained Display (ReD) identifies stable human germline antibody frameworks.

Conventional antibody surface display requires fusion protein export through at least one cellular membrane, constraining the yield and occasioning difficulties in achieving scaled production. To circumvent this limitation, we developed a novel cytoplasmic display platform, Retained Display (ReD), and used it to screen for human scFv frameworks that are highly soluble and stable in the bacterial cytoplasm. ReD, based on the retention of high-molecular weight complexes within detergent-permeabilized Escherichia coli, enabled presentation of exogenous targets to antibodies that were expressed and folded in the cytoplasm.
