Background: Colorectal cancer (CRC) often develops resistance to oxaliplatin (L-OHP), a key chemotherapeutic agent. Cancer-associated fibroblasts (CAFs) in the tumor microenvironment are implicated in chemoresistance, but their role in L-OHP resistance via interleukin-6 (IL-6) secretion remains unclear.

Objectives: The presnt study investigated how CAFs contribute to L-OHP resistance in CRC, focusing on IL-6 secretion and its impact on cancer cell survival.

Micropeptides are commonly identified as peptides encoded by non-coding RNAs (ncRNAs). In the short open reading frame (sORF) of ncRNAs, there is a base sequence encoding functional micropeptides, which is of great significance in the biological field. Recently, micropeptides regulate diverse processes, including mitochondrial metabolism, calcium transport, mRNA splicing, signal transduction, myocyte fusion, and cellular senescence, regulating the homeostasis of the internal environment and cancer's incidence and progression.

Local metasurfaces provide high flexibility in shaping wavefronts but suffer from poor frequency selectivity. Here, we numerically present a reflective all-dielectric metasurface platform achieving simultaneous local phase control and spectral filtering: it reshapes the wavefront at a specific wavelength while spatially separating it from other wavelengths without requiring additional optics. The highly efficient phase control is inherently linked to the high polarization conversion ratio (PCR), ensured by a silicon nanoblock as a narrowband reflective half-wave plate through fundamental Mie resonances.

Huygens metasurfaces exhibit excellent optical properties such as 2π phase modulation and slow light effects. However, they face challenges including wide bandwidth and low group delay due to their high radiation losses. Here, we propose a reflective Huygens metasurface coupled with an F-P cavity.

Modern all-optical logic switches demand selective, precise, and rapid transmission of optical information. In this study, we investigate an epsilon-near-zero (ENZ) metamaterial composed of silver (Ag) and magnesium fluoride (MgF), which demonstrates a low conversion threshold, strong nonlinear response, and nonlinear absorption conversion. Particularly noteworthy is its highest nonlinear absorption (β≈-2 × 10cm/GW) occurring at the ENZ point (695 nm) under deposited condition.

This perspective article delves into a novel integration of Yin-Yang theory-an ancient Chinese philosophical cornerstone-with the sophisticated realm of immunology. Given the intricate concepts inherent in immunology, many students find it challenging to comprehend the delicate mechanisms governing immune equilibrium and regulation. Given the deep-rooted understanding of Yin-Yang theory among Chinese students, we advocate for an educational strategy that contextualizes the concept of immune equilibrium within the framework of Yin-Yang, thereby offering a more intuitive and engaging learning experience.

Article Synopsis
  • A metasurface made of an indium-tin-oxide nano-step array shows weak dispersion and high optical nonlinearity, which is important for various applications like spectroscopy and quantum computing.
  • The enhanced nonlinearity is due to a balance between structural and material dispersion in a specific spectral region where the effective permittivity is near zero.
  • The metasurface maintains a nonlinear refractive index of approximately 1.5 × 10 cm GW across a wide range of wavelengths (1300 to 1510 nm), making it a promising candidate for advanced nonlinear photonic devices.

Tumor derived Extracellular vesicles (EVs) in circulating system may contain tumor-specific markers, and EV detection in body fluids could become an important tool for early tumor diagnosis, prognosis assessment. Meningiomas are the most common benign intracranial tumors, few studies have revealed specific protein markers for meningiomas from patients' body fluids. In this study, using proximity labeling technology and non-tumor patient plasma as a control, we detected protein levels of EVs in plasma samples from meningioma patients before and after surgery.

  • TMEM52B is a newly discovered tumor-related gene that is often overexpressed in nasopharyngeal carcinoma (NPC), correlating with more advanced cancer stages, higher recurrence rates, and shorter survival times.
  • Reducing TMEM52B expression decreases NPC cell growth, movement, and invasion, indicating its importance in cancer progression.
  • The gene produces two isoforms (TMEM52B-P18 and TMEM52B-P20) that differ in location and function; while both support cancer growth, TMEM52B-P20 specifically enhances metastasis by degrading E-cadherin, suggesting that targeting these isoforms might help develop new cancer treatments.

Vascular endothelial growth factor (VEGF) inhibition is an essential targeted strategy for malignant tumors, but its efficacy is severely constrained by drug resistance. The traditional view holds that the target of VEGF inhibition is endothelial cells, and thus compensatory angiogenesis is considered the main mechanism of drug resistance. In this study, we found that tumor cells themselves could develop acquired resistance to VEGF therapy, indicating an independent resistance mechanism apart from angiogenesis.

Active optical metasurfaces promise compact, lightweight, and energy-efficient optical systems with unprecedented performance. Chalcogenide phase-change material GeSbSeTe (GSST) has shown tremendous advantages in the design of mid-infrared active metasurfaces. However, most of the GSST-based active metasurfaces can only work efficiently within a narrow frequency range.

  • Endotoxin tolerance (ET) is a protective response during sepsis, and the role of peripheral T cells in ET induction is still being investigated.
  • In a study with mice, it was found that LPS injection led to significant changes in TCRβ CDR3 repertoires and an increase in F4/80 macrophages in the thymus, which indicates a role in T-cell development and ET.
  • The research concluded that TCRβ chain characteristics evolve with LPS tolerance, suggesting dynamic changes in immune responses during inflammatory conditions.

Perfect absorption over the entire visible spectrum can create a dark background for acquiring images with high contrast and improved resolution, which is crucial for various applications such as medical imaging, biological detection, and industrial non-destructive testing. The broadband absorption is desired to be achieved in an ultrathin structure for low noise as well as high integration. Here, we experimentally demonstrate a metasurface broadband perfect absorber with an ultrathin thickness of 148 nm and a large area of ∼10 cm.

  • Pregnancy-associated plasma protein A (PAPP-A) is a placental enzyme whose role in renal cell carcinoma (RCC) is not well understood, prompting this study to explore its expression and mechanisms in RCC.
  • The research found that PAPP-A is expressed at low levels in RCC tissues and its expression correlates with patient prognosis, indicating that lower levels are associated with higher RCC-related mortality.
  • Overexpressing PAPP-A in RCC cells inhibited their growth and invasiveness while altering key signaling pathways, suggesting that PAPP-A could be a valuable prognostic marker and potential therapeutic target for RCC patients.

Isocitrate dehydrogenase () mutations are common genetic abnormalities in lower grade gliomas. The neomorphic enzyme activity of IDH mutants leads to tumor formation through epigenetic alteration, dysfunction of dioxygenases, and metabolic reprogramming. However, it remains elusive as to how IDH mutants regulate the pathways associated with oncogenic transformation and aggressiveness.

Chordoma, a malignant bone cancer, is highly resistant to conventional therapeutic approaches; this greatly limits radio- and chemotherapeutic options and disease management. In the present study, we investigated three patient-derived chordoma cell lines to elucidate the molecular mechanism of resistance to therapeutics. An in vitro high-throughput chemical screening assay and an in vivo xenograft model were used to identify novel chemosensitizers for chordoma.
