Integrating Systems Biology and an Ex Vivo Human Tumor Model Elucidates PD-1 Blockade Response Dynamics

iScience, 2020
Summary: Ex vivo human tumor models have emerged as promising, yet complex tools to study cancer immunotherapy response dynamics. Here, we present a strategy that integrates empirical data from an ex vivo human system with computational models to ...

Bridging the gap between systems biology and synthetic biology

Frontiers in Microbiology, 2013
Systems biology is an inter-disciplinary science that studies the complex interactions and the collective behavior of a cell or an organism. Synthetic biology, as a technological subject, combines biological science and engineering, allowing the design ...

Complexity in cancer biology: is systems biology the answer?

Cancer Medicine, 2013
Complex phenotypes emerge from the interactions of thousands of macromolecules that are organized in multimolecular complexes and interacting functional modules. In turn, modules form functional networks in health and disease.

In vivo antihyperglycemic, antihyperlipidemic, antioxidative stress and antioxidant potential activities of Syzygium paniculatum Gaertn. in Streptozotocin-induced diabetic rats

Heliyon, 2019
Abnormal glucose metabolism causes various complications in many metabolic diseases such as obesity, hypertension, cardiovascular diseases and mainly diabetes. But commonly used oral hypoglycemic drugs cause severe side effects. Hence, there is a need to

The inherent fragility of collective proliferative control

iScience
Summary: Tissues achieve and maintain their sizes through active feedback, whereby cells collectively regulate proliferation and differentiation to facilitate homeostasis and the ability to respond to disturbances.

Atrial natriuretic peptide signaling co-regulates lipid metabolism and ventricular conduction system gene expression in the embryonic heart

iScience
Summary: It has been shown that atrial natriuretic peptide (ANP) and its high affinity receptor (NPRA) are involved in the formation of ventricular conduction system (VCS). Inherited genetic variants in fatty acid oxidation (FAO) genes are known to cause

Low dimensionality of phenotypic space as an emergent property of coordinated teams in biological regulatory networks

iScience
Summary: Cell-fate decisions involve coordinated genome-wide expression changes, typically leading to a limited number of phenotypes. Although often modeled as simple toggle switches, these rather simplistic representations often disregard the complexity

Systems immunology: When systems biology meets immunology

Frontiers in Immunology
The immune system is an intricate network of cells, proteins, and signaling pathways that coordinate protective responses and, when dysregulated, drive immune−related diseases.

Multimodal analysis unveils tumor microenvironment heterogeneity linked to immune activity and evasion

iScience
Summary: The cellular and molecular heterogeneity of tumors is a major obstacle to cancer immunotherapy. Here, we use a systems biology approach to derive a signature of the main sources of heterogeneity in the tumor microenvironment (TME) from lung ...

NKG2D-CAR-targeted iPSC-derived MSCs efficiently target solid tumors expressing NKG2D ligand

iScience
Summary: Mesenchymal stem cells (MSCs) hold potential in cancer therapy; however, insufficient tumor homing ability and heterogeneity limit their therapeutic benefits.
