A Tandem TerraSAR-X Configuration for Single-Pass SAR Interferometry [PDF]

open access: yes, 2004
TanDEM-X is a mission proposal for a TerraSAR-X add-on satellite to enable high-resolution single-pass SAR interferometry. The TanDEM-X mission has the goal of generating a global Digital Elevation Model (DEM) with an accuracy corresponding to the DTED-3

Multi‐Technique Integration Identifies O‐GlcNAc Transferase in Fibroblast‐Like Synoviocytes as a Therapeutic Target for Rheumatoid Arthritis

open access: yesAdvanced Science, EarlyView.
AI‑guided single‑cell transcriptomics identifies OGT as a key regulator enriched in rheumatoid arthritis fibroblast‑like synoviocytes (RA‐FLSs). Inflammatory stimuli activate the OGT–SAP130 axis, which modulates the H3K27ac/H3K27me3 balance and epigenetically silences BTG2, promoting aggressive transformation of RA‑FLSs.

DLST Succinylation‐Mediated Mitochondrial Metabolic Remodeling and Cuproptosis Resistance Promote Malignant Progression of Lung Adenocarcinoma

open access: yesAdvanced Science, EarlyView.
The DLST K409 succinylation mediated by CPT1A promotes OXPHOS and redox homeostasis through regulating enzyme activity, thereby promoting the malignant progression of LUAD. Notably, the succinylation of DLST can enhance the cuproptosis resistance by inhibiting its lipoylation.

HO$^\bullet$ radicals induce an unexpected high proportion of tandem base lesions refractory to repair by DNA glycosylases

open access: yes, 2010
International audienceReaction of HO• radicals with double-stranded calf thymus DNA produces high levels of 8-oxo-7,8-dihydro-2′-deoxyguanosine (8-oxodGuo) and, to a minor extent, 8-oxo-7,8-dihydro-2′-deoxyadenosine (8-oxodAdo).

m5C Reader ALYREF Promotes the Progression of Endometrial Cancer by Activating the XRCC6‐Mediated Wnt/β‐catenin Signaling Pathway

open access: yesAdvanced Science, EarlyView.
This study identifies ALYREF as an oncogenic m5C reader in endometrial cancer. ALYREF recognizes NSUN2‐mediated m5C modification on XRCC6 mRNA to enhance transcript stability and increase XRCC6 expression. Elevated XRCC6 activates Wnt/β‐catenin signaling, resulting in accelerated tumor cell proliferation, migration, invasion, and xenograft tumor growth.

A CD14‐Targeting In Situ Hydrogel Directs Macrophage Reprogramming to Minimize Scar Formation

open access: yesAdvanced Science, EarlyView.
A CD14‐targeting in situ hydrogel formed from a microbial polysaccharide rapidly remodels the immune microenvironment by reprogramming macrophage polarization, suppressing excessive inflammation, and coordinating tissue regeneration. This multifunctional hydrogel promotes scar‐reduced wound repair through enhanced angiogenesis, collagen remodeling, and

The TanDEM-X Mission Concept [PDF]

open access: yes, 2008
TanDEM-X opens a new era in space borne radar remote sensing. The first bistatic SAR mission, is formed by adding a second, almost identical spacecraft, to TerraSAR-X and flying the two satellites in a closely controlled formation with typical distances ...

Characterization and Mechanism of Formation of Tandem Lesions in DNA by a Nucleobase Peroxyl Radical

open access: yes, 2016
5,6-Dihydro-2‘-deoxyuridin-6-yl (1) was independently generated via photolysis of 3. The radical is an analogue of the major reactive species produced from thymidine upon reaction with hydroxyl radical, which is the dominant DNA-damaging agent produced ...

Chronic Stress Promotes Gastric Cancer Metastasis by Inducing Microbiota‐Associated Kynurenine Accumulation and Macrophage Remodeling

open access: yesAdvanced Science, EarlyView.
Chronic stress reshapes the gut microbiota and enriches Lactobacillus reuteri, promoting microbiota‐associated kynurenine accumulation through altered tryptophan metabolism. Kynurenine drives immunosuppressive remodeling of tumor‐associated macrophages through TNFR2–C/EBPβ signaling, thereby enhancing gastric cancer dissemination.
