Information propagation in time through allosteric signaling [PDF]

open access: yesPhys. Rev. Research 2, 023367 (2020), 2019
Naively, one expects the information communicated by an enzyme downstream within a signaling network, in which the enzyme is embedded, to grow monotonically with the enzyme's rate of product formation. However, here we observe that this does not necessarily hold true for allosterically regulated enzymes, often observed in signaling networks.

Significant correlation of angiotensin converting enzyme and glycoprotein IIIa genes polymorphisms with unexplained recurrent pregnancy loss in north of Iran [PDF]

open access: yes, 2016
Background: Spontaneous abortion is considered as the most complex problem during pregnancy. Thrombophilia is resumed as a cause of recurrent pregnancy loss (RPL). Glycoprotein IIIa (GPIIIa) gene is involved in thrombosis and abortion.

Dual‐Locking the SARS‐CoV‐2 Spike Trimer: An Amphipathic Molecular “Bolt” Stabilizes Conserved Druggable Interfaces for Coronavirus Inhibition

open access: yesAdvanced Science, EarlyView.
A new amphipathic molecule, S416 is discovered, that locks the SARS‐CoV‐2 spike protein in its closed state, blocking viral entry. S416 acts as a molecular bolt, binding six sites: three between adjacent RBDs and three connecting NTDs to RBDs. This dual‐locking mechanism stiffens the spike structure and reduces its flexibility.

Colorectal Cancer Cells–Derived Exosomal PIK3CA Mutation DNA Promotes Tumor Metastasis by Activating Fibroblast and Affecting Tumor Metastatic Microenvironment

open access: yesAdvanced Science, EarlyView.
PIK3CAH1047R DNA in colorectal cancer (CRC) cell‐derived exosomes can be delivered into recipient fibroblasts, where it is transcribed and translated, leading to the activation of fibroblasts into cancer‐associated fibroblasts, which secrete elevated levels of IL6. The simultaneous detection and targeting of PIK3CAH1047R mutation and IL6 may serve as a

Clustering and optimal arrangement of enzymes in reaction-diffusion systems [PDF]

open access: yesPhys. Rev. Lett. 110, 208104 (2013), 2013
Enzymes within biochemical pathways are often colocalized, yet the consequences of specific spatial enzyme arrangements remain poorly understood. We study the impact of enzyme arrangement on reaction efficiency within a reaction-diffusion model. The optimal arrangement transitions from a cluster to a distributed profile as a single parameter, which ...

Comparative effectiveness of enalapril, lisinopril, and ramipril in the treatment of patients with chronic heart failure: a propensity score-matched cohort study [PDF]

open access: yes, 2017
Background: Angiotensin converting enzyme inhibitors (ACEIs) are recommended as first-line therapy in patients with heart failure with reduced ejection fraction (HFrEF). The comparative effectiveness of different ACEIs is not known. Methods and results:

Comparison of First-Line Dual Combination Treatments in Hypertension: Real-World Evidence from Multinational Heterogeneous Cohorts. [PDF]

open access: yes, 2020
Background and objectives: 2018 ESC/ESH Hypertension guideline recommends 2-drug combination as initial anti-hypertensive therapy. However, real-world evidence for effectiveness of recommended regimens remains limited.
