A significant correlation exists between presence of intratumoral macrophages, tumor progression, and poor outcomes in TNBC. Preclinical in vivo studies revealed that inhibition of myelomonocytic colony stimulating factor 1 (CSF1) or its receptor (CSF1R), plus cytotoxic therapy decreases primary tumor growth kinetics and pulmonary metastases by CD8+ T cell-dependent mechanisms. To evaluate safety and tolerability of this immune-based therapeutic strategy, we conducted a phase Ib/II clinical trial evaluating Pexidartinib (PLX3397), a small molecule CSF1R inhibitor plus Eribulin chemotherapy in patients with heavily pretreated metastatic TNBC. Correlate analyses from baseline revealed increased leukocyte activation biomarkers, increased presence of CD8+ and CD4+ T central memory cells, and increased PD-1 expression on CD4+ T cells in patients experiencing a partial response or stable disease, together providing evidence of enhanced anti-tumor immunity. We hypothesized that addition of either PD-1 and PD-L1-blockade following CSF1R inhibition and chemotherapy would lead to a further enhanced anti-tumor T cell response. To test this, we evaluated tumor-bearing MMTV-PyMT transgenic mice comparing addition of PD-1- or PD-L1-blockade to Pexidartinib/Paclitaxel therapy. This revealed tumor regression in ~60% of transgenic mice with combined PD-1, but not PD-L1-blockade. Analysis of mammary tumors from mice treated with the PD-1 combination revealed activation and expansion of short-lived effector and memory T cells, and unique clonally-expanded T cells not observed with the PD-L1-blockade combination. These clinical and preclinical findings together provide rationale for addition of CSF1/CSF1R inhibitors to chemotherapy and PD-1-blocakde to further improve outcomes for patients with BC.

7.GSE294715 The membrane-associated ubiquitin ligase MARCHF8 promotes cancer immune evasion by degrading MHC class I proteins

  • ✍️ 作者:未知作者
  • 🏷️ 关键词:cancer、immune、MHC
  • 📝 描述:Contributors : Mohamed I. Khalil ; Jie Wang ; Canchai Yang ; Lexi Vu ; Smriti Chadha ; Harrison Nabors ; Daniel Vocelle ; Danielle May ; Kyle Roux ; Matthew Bernard ; Qing-Sheng Mi ; Dohun PyeonSeries Type : Expression profiling by high throughput sequencingOrganism : Mus musculusThe current immunotherapy is effective, but many cancer patients do not respond. The loss of major histocompatibility complex class I (MHC-I) molecules has been proposed as a mechanism by which cancer cells evade tumor-specific T cells in Immune Checkpoint Inhibitor (ICI)-refractory patients. Nevertheless, how cancer cells downregulate MHC-I is poorly understood. We report here that membrane-associated RING-CH-type finger 8 (MARCHF8), upregulated by human papillomavirus (HPV), ubiquitinates and degrades MHC-I proteins in HPV-positive head and neck cancer (HPV+ HNC). MARCHF8 knockdown restores MHC-I levels on HPV+ HNC cells. We further reveal that Marchf8 knockout significantly suppresses tumor growth and increases the infiltration of natural killer (NK) and T cells in the tumor microenvironment (TME). Furthermore, Marchf8 knockout markedly increases the cytotoxic NK cells and CD8+ T cells and their crosstalk with macrophages and enhances the tumor cell-killing activity of CD8+ T cells. CD8+ T cell depletion in mice abrogates Marchf8 knockout-driven tumor suppression and NK and T cell infiltration. Interestingly, Marchf8 knockout, in combination with anti-PD-1 treatment, synergistically suppresses tumor growth in mice bearing ICI-refractory tumors. Taken together, our finding suggests that MARCHF8 could be a promising target for novel immunotherapy for HPV+ HNC patients.

8.GSE244561 AtDEK2, a dual histone mark reader regulates plant immunity [RNA-seq]

Transcriptome data of the dek2-1 mutant shows that AtDEK2 is a transcriptional repressor of defense related genes, hormone synthesis & signaling genes. ChIP-Seq analysis indicates that DEK2 binds to motifs of several families of transcription factors (TFs) and to class I TCP binding motif regions with the highest affinity. We determined that DEK2 is recruited to specific regions on the chromatin by transcription factors. Our data suggests that DEK2 is a reader of the dual histone mark, H3K4me3K27me3. Finally, based on our data we postulate a hypothetical working model for the function of DEK2 as a transcriptional repressor and targets regions with H3K4me3K27me3 marks.

9.GSE310424 全转录组图谱揭示铂类抗癌药物的 RNA 依赖性机制 [RNA-seq]

  • ✍️ 作者:未知作者
  • 🏷️ 关键词:cancer、RNA-seq、transcriptome
  • 📝 描述:Contributors : Sreejith Nair ; Arun Krishnaraj ; Richi ThakralSeries Type : Expression profiling by high throughput sequencingOrganism : Homo sapiensClinically used small molecules has been predicted to off-target to RNAs. However, the extend of this interaction is small molecule cancer therapeutics has not been characterized. Here, we screened for anticancer smalll molecules for their RNA interactions and uncovered widespread RNA off-targeting. Cisplatin was found to be one among the RNA binders. We used it as a model agent to identify the specific transcripts it interact with. To accomplish this, we developed Plat-RNAseq, a click-chemistry-mediated transcriptome-wide assay. Our results revealed that cisplatin binding was enriched at guanine-rich regions capable of forming RNA G-quadruplexes (rG4s) .We found that the recruitment of cisplatin to rG4s partially contributed to its cytotoxicity, revealing a noncanonical mechanism of action for this widely used chemotherapeutic agent. RNA seq was performed to catalogue all non-ribosomal RNAs present in A2780 cells.

Here, we screened for anticancer smalll molecules for their RNA interactions and uncovered widespread RNA off-targeting. Cisplatin was found to be one among the RNA binders. We used it as a model agent to identify the specific transcripts it interact with.

Our results revealed that cisplatin binding was enriched at guanine-rich regions capable of forming RNA G-quadruplexes (rG4s). We use an rG4 ligand, carboxy-Pyridostatin (cPDS), to block access of platin-drug to rG4. This experiment test whether cPDS blocked platinum drug accumulation on cellular RNAs.

2.科学家改造细菌,使其从内部吞噬癌细胞肿瘤。

  • ✍️ 作者:未知作者
  • 🏷️ 关键词:cancer、bacteria、regex:bacter(ia|ial|ium)
  • 📝 描述:Researchers are engineering bacteria to invade tumors and consume them from the inside. Because tumor cores lack oxygen, they’re the perfect breeding ground for these microbes. The team added a genetic tweak that helps the bacteria survive longer near oxygen-exposed edges — but only once enough of them are present to trigger the change. It’s a carefully programmed biological attack that could one day offer a new way to destroy cancer.

  • 🏷️ 关键词:Alzheimer
  • 📝 描述:Scientists have created a blood test that can estimate when Alzheimer’s symptoms are likely to begin. By measuring a protein called p-tau217, the model predicts symptom onset within roughly three to four years. The protein mirrors the silent buildup of amyloid and tau in the brain long before memory loss appears. This advance could speed up preventive drug trials and eventually guide personalized care.

Instead of targeting a specific virus or bacterium, the nasal spray vaccine supercharges the lungs’ own immune defenses, keeping them on high alert for months. In mice, it slashed viral levels, prevented severe illness, and even blocked allergic reactions.

  • 📝 描述:A sweeping nationwide study has found that U.S. counties located closer to operating nuclear power plants have higher cancer death rates than those farther away. Researchers analyzed data from every nuclear facility and all U.S. counties between 2000 and 2018, adjusting for income, education, smoking, obesity, environmental conditions, and access to health care. Even after accounting for those factors, cancer mortality was higher in communities nearer to nuclear plants, particularly among older adults.

  • ✍️ 作者:未知作者
  • 🏷️ 关键词:aging
  • 📝 描述:A UCLA study in mice reveals that aging muscle stem cells accumulate a protein that slows repair but boosts survival. This protein, NDRG1, acts like a brake, preventing cells from activating quickly after injury. When researchers blocked it in older mice, muscle healing sped up dramatically — but stem cells became less resilient over time. The work suggests aging may reflect a survival trade-off rather than straightforward decline.
