Extracellular transfer of HuR promotes acquired cisplatin resistance in esophageal cancer cells

Cancer Biology & Therapy
Cisplatin (DDP) resistance is a key factor hindering esophageal cancer (ESCA) treatment. Exosomes have been reported to confer resistance to DDP in various tumor cells. However, the effects of ESCA cell-derived exosomes and exosomal human antigen R (HuR)

Towards a redefinition of the diseases within the esca complex of grapevine

Phytopathologia Mediterranea, 2009
This article proposes a new definition of the concept of esca of grapevine, and of the diseases associated with esca. A proposal is made to restrict the term ‘esca’ to grapevine wood rot, as in the past, and to apply the name ‘Grapevine leaf stripe ...

Synergistic Effects of DNA‐PKcs Inhibition and Radiotherapy in Esophageal Squamous Cell Carcinoma

The FASEB Journal, Volume 40, Issue 9, 15 May 2026.
Radiotherapy induces double‐strand DNA breaks in esophageal squamous cell carcinoma, triggering DNA‐PKcs phosphorylation and activating the non‐homologous end joining (NHEJ) repair pathway, which contributes to radioresistance. Inhibiting DNA‐PKcs disrupts this repair mechanism, enhancing radiosensitivity by blocking NHEJ, amplifying DNA damage, and ...

Correlation of the differential expression of PIK3R1 and its spliced variant, p55α, in pan‐cancer

Molecular Oncology, Volume 20, Issue 5, Page 1299-1322, May 2026.
PIK3R1 undergoes alternative splicing to generate the isoforms, p85α and p55α. By combining large patient datasets with laboratory experiments, we show that PIK3R1 spliced variants shape cancer behavior. While tumors lose the protective p85α isoform, p55α is overexpressed, changes linked to poorer survival and more pronounced in African American ...

Ecophysiological impacts of Esca, a devastating grapevine trunk disease, on Vitis vinifera L.

PLoS ONE, 2019
Esca is a Grapevine Trunk Disease (GTD) caused by a broad range of taxonomically unrelated fungal pathogens. These attack grapevine wood tissues inducing necroses even in the conductive vascular tissues, thus affecting the vine physiology and potentially

Counterion‐Controlled Photocatalytic Doping of Organic Semiconductors

Advanced Materials, Volume 38, Issue 25, 4 May 2026.
Counterion size is shown to actively control photocatalytic doping in organic semiconductors. Small anions suppress aggregation of acridinium photocatalysts, enhance electron transfer, and dramatically increase doping efficiency. This simple strategy enables conductivities up to 2000 S cm−1 in benchmark polymers, revealing counterions as a powerful yet
