Summary: Aberrant glycosylation is a hallmark of colorectal cancer, and this study reveals the distinct N-glycomic profiles of different cell types in CRC tissues. Cancer cells show increased expression of certain N-glycan structures and decreased expression of others compared to normal mucosa, while stromal cells exhibit different expression patterns.

Summary: This study investigated the effects of capsaicin and allyl isothiocyanate on the gastrointestinal tract. It was found that they activate TRPV1 and TRPA1, leading to ion secretion and transport in the GI mucosa. The results also showed that TRPV1 signaling is regulated by submucosal neurons and epithelial NK1 receptor activation, while TRPA1 signaling is regulated by endogenous prostaglandins and EP4 receptor activation.

Summary: LAG-3, a transmembrane immune checkpoint, plays a role in immune escape in gastric cancer by suppressing T-cell-mediated anti-tumor immunity. Our study showed that LAG-3 expression was associated with poorer clinical outcomes in EBV-positive and MLH1-defective gastric cancer, suggesting it as a potential immunotherapeutic target.

Summary: The study found that TNF receptor type II (TNFR2) is expressed in a wide range of tumor cells. Knocking out TNFR2 in mouse colon cancer cells MC38 and CT26 using CRISPR/Cas9 technology inhibited in vitro proliferation and colony formation of cancer cells through inhibition of AKT phosphorylation and promotion of autophagy-induced cell death. In addition, TNFR2 deficiency significantly impaired the in vivo growth of MC38 or CT26 tumors in mice, accompanied by a decrease in soluble TNFR2 levels in the circulation and an increase in the number of tumor-infiltrating IFN gamma+ CD8 cells.

Summary: The study reveals a negative correlation between ETV4 expression and DNA methylation, and a positive correlation between ETV5 expression and DNA methylation in colon cancer tissue. Additionally, higher ETV5 expression is associated with shorter relapse-free survival in colon cancer patients receiving adjCTX treatment.

Summary: This study examined the differences in immune signatures among LS patients, non-LS patients, and patients with and without a history of colorectal cancer. The findings suggest the existence of immune features specific to LS-status and CRC history, which may help in assessing CRC risk in individuals with LS and identifying prevention targets.

Summary: In contrast to microsatellite stable (MSS) colon cancer, lymph node metastases are less prevalent in microsatellite instability (MSI) colon cancer, but the factors associated with lymph node metastases are similar to MSS colon cancer. In N2 disease, MSI patients have a lower rate of 3-year recurrence-free survival compared to MSS patients.

Summary: Ovaries play a crucial role in the development, fertility, and reproduction of women. They age faster than other tissues and their function is lost before other organs undergo senescence. While there have been debates about the presence of germline stem cells and neo-oogenesis in adult human ovaries, our recent analysis did not find evidence of such stem cells. However, we welcome discussions on different protocols and acknowledge the importance of excellence in methods.

Summary: CRISPR/Cas9-mediated genome-wide knockout screening identified 24 reprogramming roadblock genes, among which depletion of the predicted KRAB zinc finger protein Zfp266 consistently enhanced murine iPSC generation in various reprogramming settings. ZFP266 was found to bind to Short Interspersed Nuclear Elements (SINEs) near the binding sites of OCT4, SOX2, and KLF4, inhibiting chromatin opening. Replacement of the KRAB co-suppressor with co-activator domains transformed ZFP266 from an inhibitor to a potent facilitator of iPSC reprogramming. The interaction between SINE and KRAB-ZFP is proposed to be a critical regulator of chromatin accessibility for efficient cellular identity changes.

Summary: This study used a genome-wide association study to uncover the genetic factors underlying preeclampsia and maternal hypertension during pregnancy. The analysis identified several novel genetic associations and found that genes related to blood pressure traits are also associated with preeclampsia. These findings suggest a connection between cardiovascular function and the development of preeclampsia.

Summary: LEUTX, a transcription factor, is expressed in human preimplantation embryos at the 4-8 cell stages and silenced in somatic tissues. Through multiomic characterization, we found that LEUTX interacts with histone acetyltransferases, EP300 and CBP, via its 9 amino acid transactivation domain. It targets genomic cis-regulatory sequences overlapping with repetitive elements and functions as a transcriptional activator, upregulating genes involved in preimplantation development and 8-cell-like markers.

Summary: This study discovered the physical protein-protein interaction between DYX1C1 and DCDC2 genes, as well as their interactions with the centrosomal protein CPAP. It also found a synergistic genetic interaction between dyx1c1 and dcdc2b in zebrafish, exacerbating the ciliary phenotype. Furthermore, a mutual effect on transcriptional regulation was observed between DYX1C1 and DCDC2 in a cellular model.

Summary: Inorganic polyphosphates are bioactive phosphate polymers found in all living organisms, and in mammals, they play a vital role in regulating cellular metabolism, coagulation, and inflammation. Long-chain polyphosphates, particularly P700, can modulate the type I interferon signaling and cytokine secretion in human leukocytes. P700 treatment decreases interferon signaling and subsequent gene expression, while augmenting the secretion of various cytokines. This study demonstrates the extensive modulatory effects of P700 on cytokine signaling, specifically targeting type I interferon signaling in human leukocytes.
