Loss of IGF‐1R impairs DNA‐PKcs recruitment to chromatin leading to defective end‐joining

Molecular Oncology, EarlyView.
IGF‐1R promotes radioresistance by facilitating DNA‐PKcs recruitment to chromatin, enabling non‐homologous end‐joining (NHEJ) repair of double‐strand breaks. Inhibition or loss of IGF‐1R disrupts this recruitment to damage sites, driving compensatory reliance on microhomology‐mediated end‐joining (MMEJ) repair.

USP29‐regulated noncanonical stabilization of the hypoxia‐inducible factor‐α in aggressive prostate cancer

Molecular Oncology, EarlyView.
We identify USP29 as the only DUB mirroring CA9 expression, a marker of hypoxia and HIF pathway activation associated with PCA aggressiveness. USP29 stabilizes HIF‐1α and HIF‐2α via a noncanonical mechanism that is independent of PHD/pVHL activity yet relies on proteasomal regulation, establishing USP29 as a previously unrecognized regulator of hypoxic

Dragonfly red opsins share a common tuning mechanism with mammalian red opsins and further enhancement of near-infrared sensitivity

Cellular and Molecular Life Sciences
Some animals, such as primates and insects have color vision including sensitivity to red light (red vision). Red vision is basically achieved through opsins sensitive to the red region (red opsins), which independently evolved in different lineages.

Use of fluorescence imaging and spectrometry in detection of oral squamous cell carcinoma and oral potentially malignant disorders

Oral Oncology Reports
Objective: Changes in the autofluorescence of cancerous tissue in comparison to normal tissue due to alteration in the endogenous fluorophores and protein like NAD and FAD has been utilized in various oral cancer screening devices.

Longitudinal genome‐wide aneuploidy measurements in circulating cell‐free DNA to predict lack of benefit from pembrolizumab in patients with metastatic urothelial cancer

Molecular Oncology, EarlyView.
Many patients with urothelial cancer do not benefit from treatment with pembrolizumab, while at risk of severe side effects. Changes in the levels of circulating tumor DNA early during treatment, measured by a simple and affordable assay that can be easily implemented in the clinic, can be used as a prognostic tool to identify these patients.

Photon frequency variation in non-linear electro-magnetism

Physics Letters B
We set a generalised non-linear Lagrangian, encompassing Born-Infeld and Heisenberg-Euler theories among others. The Lagrangian reduces to the Maxwell Lagrangian at lowest order.

A novel quinazolinone insulin receptor inhibitor and its synergy with an EGFR inhibitor in glucose‐driven glioblastoma

Molecular Oncology, EarlyView.
The novel styrylquinazolinone‐based molecule W1B effectively suppresses glioblastoma by inhibiting IGF1R and EGFR. In high‐glucose microenvironments driving tumor resistance, W1B acts synergistically with the EGFR inhibitor dacomitinib. This combination safely blocks compensatory survival signaling in zebrafish xenograft models. Showcasing promising in

Oncogenic DMTF1β promotes cancer cell motility by regulating autophagy through ULK1 stabilization

Molecular Oncology, EarlyView.
In the current study, we demonstrate that the oncogene DMTF1β regulates ULK1 stability by reducing its proteasomal degradation in cancer cells. This stabilization enables ULK1 to induce autophagy, which in turn facilitates cancer cell migration. Consequently, reduced DMTF1β levels lead to decreased autophagy and impaired cancer cell migration.

The solar red-shift

, 1961
Shortly after Rowland's fundamental study of the wavelengths of Fraunhofer lines, Jewell in 1896 observed that the solar wavelengths were shifted to the red side of the corresponding wavelengths observed in the laboratory. This shift became known as the red shift of solar lines, and at first led to various erroneous concepts of conditions in the solar ...

Ultrasensitive bionic photonic-electronic skin with wide red-shift mechanochromic response

Light: Advanced Manufacturing
Mimicking animal skin is an effective strategy for enhancing the performance of artificial skin. Inspired by a chameleon’s iridophore and a spider’s slit organ, a novel photonic-electronic skin (PE-skin) with excellent optical/electrical dual-sensing ...
