EFFECTIVE ANTIBODY RESPONSE OF AFRICAN WILD DOGS () TO CANINE DISTEMPER VACCINATION WITH A LIVE ATTENUATED VACCINE.

Vaccinating African wild dogs () against canine distemper virus (CDV) using live attenuated vaccines (LAV) has been controversial because of limitations in the vaccines' effectiveness and safety. However, CDV is a significant pathogen for African wild dogs, and CDV LAV are currently the only vaccines readily available on the African continent, making them a crucial tool for conservation. There are few studies exploring immunogenicity of CDV LAV, and even less information pertaining to optimal vaccination protocols.

Next generation organoid engineering to replace animals in cancer drug testing.

Cancer therapies have several clinical challenges associated with them, namely treatment toxicity, treatment resistance and relapse. Due to factors ranging from patient profiles to the tumour microenvironment (TME), there are several hurdles to overcome in developing effective treatments that have low toxicity that can mitigate emergence of resistance and occurrence of relapse. De novo cancer development has the highest drug attrition rates with only 1 in 10,000 preclinical candidates reaching the market.

A Novel Mechanism of Ataxia Telangiectasia Mutated Mediated Regulation of Chromatin Remodeling in Hypoxic Conditions.

The effects of genotoxic stress can be mediated by activation of the Ataxia Telangiectasia Mutated (ATM) kinase, under both DNA damage-dependent (including ionizing radiation), and independent (including hypoxic stress) conditions. ATM activation is complex, and primarily mediated by the lysine acetyltransferase Tip60. Epigenetic changes can regulate this Tip60-dependent activation of ATM, requiring the interaction of Tip60 with tri-methylated histone 3 lysine 9 (H3K9me3).

Preclinical Evaluation of Ureidosulfamate Carbonic Anhydrase IX/XII Inhibitors in the Treatment of Cancers.

Carbonic anhydrases (CAs) are a family of enzymes involved in the pH regulation of metabolically active cells/tissues. Upregulation of the CAIX/XII isoforms is associated with hypoxic tumours and clinically linked with malignant progression, treatment resistance and poor prognosis. The elucidation of the crystal structure of the catalytic domains of CAIX/XII provided the basis for the generation of CAIX/XII selective inhibitors based on the sulfonamide, sulfamate and coumarins chemical structures.

A new method for the high-precision assessment of tumor changes in response to treatment.

Motivation: Imaging demonstrates that preclinical and human tumors are heterogeneous, i.e. a single tumor can exhibit multiple regions that behave differently during both development and also in response to treatment.
