Regulation of Refractive Index by Halogens in Two-Dimensional Layered Methylsulfonate Halides.

Herein, a series of unprecedented alkaline earth metal methylsulfonate halides, M(SOCH)X·HO (M = Sr, Ba; X = Cl, Br, I; = 2, 4), and Ba(SOCH)I·4HO were synthesized. They all feature two-dimensional (2D) layered structures with halogen elements inserted between the 2D layers constructed by metal ions and [SOCH] groups, which are suitable for exploring the influence of halogens on their refractive index. The refractive indexes both parallel and (almost) perpendicular to the 2D layers were calculated through theoretical calculations.

Lithium Borate-Squarate: An Organic-Inorganic Groups-Mixed Nonlinear Optical Crystal with Large Birefringence.

Targeting polyploid giant cancer cells potentiates a therapeutic response and overcomes resistance to PARP inhibitors in ovarian cancer.

To understand the mechanism of acquired resistance to poly(ADP-ribose) polymerase inhibitors (PARPi) olaparib, we induced the formation of polyploid giant cancer cells (PGCCs) in ovarian and breast cancer cell lines, high-grade serous cancer (HGSC)-derived organoids, and patient-derived xenografts (PDXs). Time-lapse tracking of ovarian cancer cells revealed that PGCCs primarily developed from endoreplication after exposure to sublethal concentrations of olaparib. PGCCs exhibited features of senescent cells but, after olaparib withdrawal, can escape senescence via restitutional multipolar endomitosis and other noncanonical modes of cell division to generate mitotically competent resistant daughter cells.

Evolution of immune and stromal cell states and ecotypes during gastric adenocarcinoma progression.

Understanding tumor microenvironment (TME) reprogramming in gastric adenocarcinoma (GAC) progression may uncover novel therapeutic targets. Here, we performed single-cell profiling of precancerous lesions, localized and metastatic GACs, identifying alterations in TME cell states and compositions as GAC progresses. Abundant IgA plasma cells exist in the premalignant microenvironment, whereas immunosuppressive myeloid and stromal subsets dominate late-stage GACs.

Honeycomb layered topology construction for exceptional long-wave infrared nonlinear optical crystals.

Nonlinear optical (NLO) crystals capable of efficient long-wave infrared (8-14 μm) laser output remain scarce, and the exploration of long-wave IR NLO materials with superior comprehensive optical performances is a momentous challenge. Herein, we develop two selenide-halide NLO crystals, HgAsSeBr and HgAsSeI, which are derived from the honeycomb layered topology of prototype GaSe. Remarkably, they exhibit not only strong SHG effects, suitable band gap, large birefringence, broad IR transparency range and low two-photon absorption coefficients but reinforced interlayer interaction and more benign crystal growth habit, compared to those of GaSe, indicating that they are promising long-wave IR NLO materials.

Gankyrin-mediated interaction between cancer cells and tumor-associated macrophages facilitates prostate cancer progression and androgen deprivation therapy resistance.

Increasing evidence reveals that the interaction between tumor cells and tumor-associated macrophages (TAMs) facilitates the progression of prostate cancer, but the related mechanisms remained unclear. This study determined how gankyrin, a component of the 19S regulatory complex of the 26S proteasome, regulates the progression and androgen deprivation therapy (ADT) resistance of prostate cancer through tumor cell-TAM interactions. functional experiments and subcutaneous tumor models were used to explore the biological role and molecular mechanisms of gankyrin in prostate cancer cell-TAM interactions.

Newly designed breakapart FISH probe helps to identify cases with true MECOM rearrangement in myeloid malignancies.

A home-brew, tri-color MECOM breakapart FISH probe with a full MECOM coverage labeled with a separate dye is compared in parallel with a 2-color commercial MECOM breakapart probe in 17 cases of hematologic malignancies. Cases with a typical positive signal pattern (or "balanced" signal pattern) (n = 2) and a negative result (n = 3) using the commercial probe achieved the same results using the new probe (100% concordance), whereas 9 of 12 (75%) remaining cases with an atypical signal pattern (or "unbalanced" signal pattern) using the commercial probe showed a "balanced" signal pattern using the new probe. Three cases with undetermined MECOM rearrangement status by the commercial probe were further clarified with no MECOM rearrangement in 2 cases and presence of a subclone with simultaneous gain and rearrangement of MECOM in 1 case.

Integrative Analysis Identifies Multi-Omics Signatures That Drive Molecular Classification of Uveal Melanoma.

By iCluster analysis, we found that the integrative molecular classification of the UM was primarily driven by DNA copy number variation on chromosomes 3, 6 and 8, differential methylation and expression of genes involved in the immune system, cell morphogenesis, movement and migration, and differential mutation of genes including , , , and . Integrative analysis revealed that pathways including IL6/JAK/STAT3 signaling, angiogenesis, allograft rejection, inflammatory response and interferon gamma response were hypomethylated and up-regulated in the M3 iSubtype, which was associated with a worse overall survival, compared to the D3 iSubtype. Using two independent gene expression datasets, we demonstrated that the subtype-driving genes had an excellent prognostic power in classifying UM into high- or low-risk groups for metastasis.
