A Nanoscaffolded Spike-RBD Vaccine Provides Protection against SARS-CoV-2 with Minimal Anti-Scaffold Response

David Hacker, Bruno Emanuel Ferreira De Sousa Correia, Florence Pojer, Kelvin Ka Ching Lau

The response of the adaptive immune system is augmented by multimeric presentation of a specific antigen, resembling viral particles. Several vaccines have been designed based on natural or designed protein scaffolds, which exhibited a potent adaptive imm ...

Analysis of volumetric mass transfer coefficient (k(L)a) in small- (250 mL) to large-scale (2500 L) orbitally shaken bioreactors

Florian Maria Wurm, David Hacker, Likuan Zhu

In this study, the combination of dimensional analysis (DA) and analysis of variance (ANOVA) was used to predict the volumetric mass transfer coefficient (k(L)a) values under different operating conditions for orbitally shaken bioreactors (OSRs) with diffe ...

The human membrane protein Angiotensin-converting enzyme 2 (hACE2) acts as the main receptor for host cells invasion of the new coronavirus SARS-CoV-2. The viral surface glycoprotein Spike binds to hACE2, which triggers virus entry into cells. As of today, ...

Chromatin three-dimensional interactions mediate genetic effects on gene expression

David Hacker, Giovanna Ambrosini, Philipp Bucher, Sanjeev Kumar

Studying the genetic basis of gene expression and chromatin organization is key to characterizing the effect of genetic variability on the function and structure of the human genome. Here we unravel how genetic variation perturbs gene regulation using a da ...

BRB-seq: ultra-affordable high-throughput transcriptomics enabled by bulk RNA barcoding and sequencing

Bart Deplancke, David Hacker, Bastien Mangeat, Vincent Roland Julien Gardeux, Julie Marie Russeil, Daniel Alpern, Antonio Carlos Alves Meireles Filho

Despite its widespread use, RNA-seq is still too laborious and expensive to replace RT-qPCR as the default gene expression analysis method. We present a novel approach, BRB-seq, which uses early multiplexing to produce 3 cDNA libraries for dozens of sample ...

Expression proteomics study to determine metallodrug targets and optimal drug combinations

Paul Joseph Dyson, Kai Johnsson, David Hacker, Claire Samantha Allardyce

The emerging technique termed functional identification of target by expression proteomics (FITExP) has been shown to identify the key protein targets of anti-cancer drugs. Here, we use this approach to elucidate the proteins involved in the mechanism of a ...

Heterogenous populations of recombinant cells (cell pools) stably expressing 1-4 transgenes were generated from Chinese hamster overy (CHO) cells with the piggyBac (PB) transposon system. The cell pools produced different combinations of three model protei ...

Comparison of Three Transposons for the Generation of Highly Productive Recombinant CHO Cell Pools and Cell Lines

Florian Maria Wurm, David Hacker, Lucia Baldi Unser, Yashas Rajendra, Sowmya Balasubramanian

Several naturally occurring vertebrate transposable elements have been genetically modified to enable the transposition of recombinant genes in mammalian cells. We compared three transposonspiggyBac, Tol2, and Sleeping Beautyfor their ability to generate c ...
