To evaluate the efficacy of a novel histone deacetylase inhibitor, chidamide, in combination with rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (CR-CHOP) in the treatment of DEL. The most common grades 3-4 hematologic and nonhematologic toxicity were leukopenia (46.7%) and infection (21%), respectively. This long-term follow-up study indicates that CR-CHOP in untreated DLBCL with the DEL phenotype demonstrates high short-term efficacy and safety as well as promising survival outcomes.

Chidamide combined with (+)-JQ-1 can inhibit the proliferation of MLL-r AML cells, inhibit the initiation of protective self-repair of these leukemia cells by inhibiting the DNA damage response pathway, and ultimately increase the apoptosis of these cells, but non- MLL-r AML cells have no similar results.

Our results revealed the relationships among the ERα, PI3K/AKT, and MAPK signaling pathways in ER+ breast cancer cells. Understanding the interactions among ERα, PI3K-AKT-mTOR, and MAPK could lead to novel combination therapies.

Our study suggested that chidamide exerts an antitumor effect on T-LBL/ALL and promotes a more inflammatory form of cell death via the FOXO1/GSDME axis, which provides a novel choice of targeted therapy for patients with T-LBL/ALL.

Concomitant inhibition of both FAK (with VS-4718) and rapidly accelerated fibrosarcoma and MAPK kinase (RAF-MEK) (with avutometinib) induced tumor growth inhibition and increased survival across multiple PDAC mouse models. Combination of FAK and RAF-MEK inhibition alone improved antitumor immunity and priming of T cell responses in response to chemotherapy. These findings provided the rationale for an ongoing clinical trial evaluating the efficacy of avutometinib and defactinib in combination with gemcitabine and nab-paclitaxel in patients with PDAC and may suggest further paths for combined stromal and tumor-targeting therapies.

Using patient tumor tissue before and after BRAFi+MEKi, two novel syngeneic murine models of BRAF V600E HGG, and patient-derived cell lines, we examined the effects of clinically relevant BRAFi+MEKi with dabrafenib and trametinib on tumor growth, cell states, and tumor-infiltrating T cells. The quadruple treatment overcame BRAFi+MEKi resistance by invigorating T cell-mediated anti-tumor immunity in murine BRAF V600E HGG. PD-L1 expression was elevated in human BRAF-mutant versus BRAF-wildtype glioblastoma clinical specimen, complementing experimental findings and suggesting translational relevance for patient care.

Among them, compound 20 exhibited potential inhibitory activity on HDAC1, and demonstrated notable potency against RPMI-8226 cells with an IC50 value of 2.89 ± 0.43 μM, which was better than chidamide (IC50 = 10.23 ± 1.02 μM)...The ADME parameters calculation showed that 20 possesses remarkable theoretical drug-likeness properties. Taken together, these results suggested that 20 is worthy of further exploration as a potential HDAC-targeted anticancer drug candidate.

The ERK-inhibitor GDC-0994 blocked phosphorylation of MEK/ERK and suppressed TGM2 and MMP7. TGM2 communicates with MMP7 in colon cancer cells forces cell migration and invasion by the MEK/ERK signaling pathway and triggers EMT. Inhibiting TGM2 could thus offer new therapeutic options to treat patients with colon cancer, particularly to prevent metastatic progression.

Latency establishment was mimicked by culturing HSV-1 infected ND7/23 cells in the presence of acyclovir (ACV) for 3 days...There were no changes in the pharmacological and biophysical properties of sodium currents promoted by TNF-α, including sensitivity to tetrodotoxin and the current-voltage relationship...Inhibition of p38 signaling with SB203580 or SB202190 eliminates the stimulatory effect of TNF-α on sodium currents. These results indicate that TNF-α signaling in sensory neurons during latency establishment upregulates the expression of voltage-gated Na+ channels in order to maintain the transmission of pain information.

This study presents evidence that parecoxib enhances the anti-cancer power of resveratrol in DLD-1 colorectal cancer cells via the inhibition of TXNDC5 and Akt signaling and enhancement of JNK/p38 MAPK pathways. Parecoxib may be provided as an efficient drug to sensitize colorectal cancer by resveratrol.

Finally, we discovered that AIBP could control the MAPK signaling pathway-involved genes expression, including P-MEK, MEK, c-Myc, P-ERK1/2, and ERK1/2, and that GDC-0994, a specific ERK1/2 inhibitor, could suppress the AIBP overexpression induced cell migration and proliferation abilities. These findings demonstrated that the ERK/MAPK signaling pathway might be stimulated by AIBP in HCC tissues, leading to increased cell invasion, migration, and proliferation. It was hypothesized that AIBP might act as a useful prognostic and diagnostic marker for HCC.

Importantly, tumor growth inhibition by HDAC inhibition was dependent on SULF1 expression in CAFs, and CRC patients with more SULF1+ CAFs were more responsive to treatment with the HDAC inhibitor chidamide. Collectively, these findings unveil the critical role of SULF1+ CAFs in CRC and provide a strategy to stratify CRC patients for HDAC inhibitor treatment.

Here we report chidamide maintenance therapy after allo-HSCT in patients with SET-NUP214 fusion positive T-ALL. Both patients improved effectively during follow-up, confirming the efficacy of chidamide in improving the condition of these patients and may provide valuable clinical information for the treatment of this rare and understudied disease.

Furthermore, BCE significantly inhibited the growth of NSCLC cells SPC-A1 in nude mice and downregulated Ras, Raf, Akt, and p-Akt expression in vivo. The antitumor effects of BCE suggest its potential clinical application in patients with NSCLC, especially in those bearing Ras or Raf mutations.

Nonresponding melanoma cells are identified in all transcriptional cell states and are predisposed to BRAF/MEK inhibitor resistance due to pro-inflammatory IL6 and TNFɑ signalling. Our study provides a framework to study treatment response within distinct melanoma cell states and indicate that tumour-intrinsic pro-inflammatory signalling contributes to BRAF/MEK inhibitor resistance.

We conducted an open-label, phase 2 nonrandomised, externally controlled study to evaluate the efficacy and safety of targeted agents plus CHOP (cyclophosphamide, doxorubicin, vincristine, and prednisolone) (CHOPX) for PTCL in the front-line setting...Specific targeted agents were added from Cycle 2, decitabine if TP53 mut, azacytidine if TET2/KMT2D mut, tucidinostat if CREBBP/EP300 mut, and lenalidomide if without mutations above...Biomarker-driven therapeutic strategy is feasible and may lead to promising efficacy specifically toward molecular features in PTCL. This study was supported by the National Key Research and Development Program (2022YFC2502600) and the General Program of the Shanghai Municipal Health Commission (202040400).
