1.GSE317661 CSN3促进胃癌侵袭,并通过激活NOD/TLR通路与免疫浸润相关

  • ✍️ 作者:未知作者
  • 🏷️ 关键词:cancer、immune、TLR
  • 📝 描述:Contributors : Gang Wang ; Dalai Xu ; Lei Qiu ; Feng Lu ; Yongchang MiaoSeries Type : Expression profiling by high throughput sequencingOrganism : Homo sapiensWe found that CSN3 is highly expressed in gastric cancer and is associated with advanced tumor stage, lymph node metastasis, and poor prognosis. Functional assays showed that CSN3 promotes proliferation and migration while inhibiting apoptosis in GC cells. RNA-sequencing revealed that CSN3 overexpression predominantly activates innate immune–related pathways, particularly the NOD-like receptor and Toll-like receptor signaling pathways, suggesting a role for CSN3 in inflammatory and immune remodeling of the tumor microenvironment. Consistently, CSN3 expression was positively correlated with B-cell and CD8⁺ T-cell infiltration, indicating that CSN3-driven transcriptional programs may link tumor aggressiveness with immune microenvironment alterations.

  • ✍️ 作者:未知作者
  • 🏷️ 关键词:immune、immunity、resistance
  • 📝 描述:Contributors : Zhouting Zhu ; Zhaoyang Jia ; Tariq M RanaSeries Type : Expression profiling by high throughput sequencingOrganism : Mus musculusImmune Checkpoint Therapy (ICT) has demonstrated durable responses and long-lasting immunologic memory in cancer treatment. However, overcoming primary and acquired resistance remains a major challenge. Here, we show that CRISPR-Cas9-mediated deletion of miRNA-25 (miR-25) sensitizes tumors to ICT across three syngeneic mouse tumor models. Single-cell RNA sequencing (scRNA-seq) of the tumor microenvironment (TME) revealed that miR-25 deficiency induces innate immunity by upregulating major histocompatibility complex class II (MHC II) in antigen-presenting M1-like macrophages and enhances the classical complement cascade in cancer-associated fibroblasts (CAFs) to drive a humoral immune response. The complement activation polarizes CAFs from myofibroblastic CAFs (myCAFs) toward inflammatory CAFs (iCAFs) while simultaneously reduces immune-suppressive interactions between CAFs and tumor associated macrophages (TAMs). This shift results in a reduced macrophage population and fosters a pro-inflammatory, anti-tumor TME. Syndecan-3 (Sdc3), a membrane proteoglycan expressed in tumors, is repressed by miR-25 through miRISC (microRNA induced silencing complex) upon IFN-γ exposure. Using an adenine base editor (ABE8e) to mutate the miR-25 binding site in the 3’ untranslated region (3’ UTR) of Sdc3 effectively overcomes the resistance. The repression of SDC3 by miR-25 is further validated in five human cancer cell lines upon IFN-γ exposure but remains unaffected in non-cancerous cells. These findings identify miR-25 as a key driver of initial resistance through the repression of SDC3 and demonstrate that miR-25 deletion or stabilization of SDC3 could transform immune resistant “cold” tumors into immune responsive “hot” tumors, offering therapeutic avenues to enhance cancer immunotherapy.

9.GSE309890 抗抑郁药舍曲林通过应激驱动的磷酸戊糖途径重编程导致耐药性产生:tktA 使代谢回滚

  • ✍️ 作者:未知作者
  • 🏷️ 关键词:metabolic、resistance、pathway
  • 📝 描述:Contributors : Yueting Cui ; Shiyuan Xue ; Jianhua Guo ; Chengdong ZhangSeries Type : Expression profiling by high throughput sequencingOrganism : Escherichia coli str. K-12 substr. MG1655Selective serotonin reuptake inhibitors (SSRIs) may accelerate antibiotic resistance, but the metabolic changes behind this process—and how to restore susceptibility—are still not well understood. We demonstrated that sertraline led to a biased resistance profile in Escherichia coli, characterized by early accumulation of mutations targeting rifampicin and ciprofloxacin. These genetic alterations were linked to a compensatory respiratory mechanism dependent on Complex I, leading to reduced nicotinamide adenine dinucleotide and superoxide/hydrogen peroxide buildup. They also caused a rapid shift of glucose from glycolysis to the pentose-phosphate pathway (PPP) to produce reduced nicotinamide adenine dinucleotide phosphate during oxidative stress, similar to paraquat-like redox stress. Inhibiting the non-oxidative PPP, especially transketolase A (tktA), eliminated the sertraline-primed advantage and brought back antibiotic susceptibility, decreasing survival by approximately 10,000 times during antibiotic challenge, even with rpoBC and gyrAB mutations fixed. These findings uncover an electron transfer chain/PPP–coupled redox module as the hidden driver behind sertraline-induced resistance, highlighting mutation-agnostic ways to restore bacterial sensitivity. By reframing SSRI-induced resistance as a modifiable metabolic trait, we provide a basis for using metabolic adjuvants to shield the millions of SSRI users from the unintended risk of antibiotic resistance—transforming a pharmacological challenge into a manageable, reversible target
