The Natural Product Corramycin Acts as a DNA Gyrase Poison and Overcomes Fluoroquinolone Resistance in Mycobacterium tuberculosis

open access: yesAdvanced Science, EarlyView.
Corramycin, a myxobacterial natural product antibiotic, exhibits potent bactericidal activity against multidrug‐resistant Mycobacterium tuberculosis. The compound hijacks bacterial transporters such as BacA and OppABCD to enter the cell and inhibits DNA synthesis through a previously unrecognized mode of DNA gyrase poisoning, locking the enzyme in an ...

A Novel Pak1 Activator Ameliorates ER Stress for HFpEF Therapy

open access: yesAdvanced Science, EarlyView.
Chronic metabolic stress is a major contributor to HFpEF progression. Under prolonged metabolic stress, Pak1 activity becomes impaired, contributing to disrupted ER proteostasis, cardiomyocyte apoptosis, fibrosis, and diastolic dysfunction. Mechanistically, Pak1 overexpression activates the ERK1/2–MNK1–eIF4E signaling axis, promotes translational ...

Serine proteases and protease‐activated receptor 2 mediate the proinflammatory and algesic actions of diverse stimulants [PDF]

open access: yes, 2014
Background and purposeAlthough serine proteases and agonists of protease-activated receptor 2 (PAR2) cause inflammation and pain, the spectrum of proteases that are activated by proinflammatory and algesic stimuli and their contribution to inflammatory ...

Repurposing a Small Molecule Plant Hormone as a Tunable ON‐Switch for CAR‐T Cell Immunotherapy

open access: yesAdvanced Science, EarlyView.
By engineering a receptor system integrating the plant auxin receptor AFB1 with its co‐receptor IAA7, we enable ligand‐dependent interactions triggered by the plant hormone auxins. This design allows rapid, reversible, and dose‐dependent T cell activation, resulting in potent cytotoxicity against B‐cell lymphoma in vitro and in vivo.

Serine proteases in bone disease

open access: yes, 2009
Serine proteases are active in many physiological and pathological processes within bone tissue. Although essential to adequate maintenance of bone and cartilage, their inappropriate expression can lead to exacerbation of tissue destruction and ...

VlPAG/DRN Microglia Drive Neuropathic Pain‐Induced Depression via a Defined Neuroimmune Axis

open access: yesAdvanced Science, EarlyView.
Peripheral nerve injury (SNI) induces neuropathic pain, activates midbrain microglia, and triggers an NLRP3–IL‐1β–dependent inflammatory cascade. IL‐1β signals through IL‐1R1 on vlPAG/DRN VGLUT2+ neurons (vlPAG/DRNGlu), inducing hyperexcitability and driving the vlPAG/DRNGlu→BNSTGABA circuit to produce the affective component of neuropathic pain ...

Nucleoside‐Modified mRNA Encoding Alpha‐Galactosidase A Ameliorates Fabry Disease Phenotypes in Human IPSC‐Derived Cardiomyocytes

open access: yesAdvanced Science, EarlyView.
Human iPSC‐derived Fabry cardiomyocytes exhibited broad transcriptional dysregulation, apoptosis, mitochondrial dysfunction, impaired reactive oxygen species handling, altered contractility, and abnormal calcium transient decay, potentially mediated by phospholamban hyperphosphorylation.

Selective Modulation of OTUB1 Noncanonical Function via a bioPhosTAC Strategy

open access: yesAdvanced Science, EarlyView.
This work positions the versatile performance of the peptide‐based bioPhosTAC platform for dissecting phosphorylation‐dependent biology and expanding the scope of induced‐proximity technologies. We demonstrated that selective manipulation of a tyrosine phosphorylation site is sufficient to propagate coordinated cellular consequences.

Membrane-Anchored Serine Proteases in Vertebrate Cell and Developmental Biology

open access: yes, 2011
Analysis of vertebrate genome sequences at the turn of the millennium revealed that a vastly larger repertoire of enzymes execute proteolytic cleavage reactions within the pericellular and extracellular environments than was anticipated from biochemical
