Aging as a loss of morphostatic information: a developmental bioelectricity perspective
Ageing Res Rev. 2024 Apr 16:102310. doi: 10.1016/j.arr.2024.102310. Online ahead of print.ABSTRACTMaintaining order at the tissue level is crucial throughout the lifespan, as failure can lead to cancer and an accumulation of molecular and cellular disorders. Perhaps, the most consistent and pervasive result of these failures is aging, which is characterized by the progressive loss of function and decline in the ability to maintain anatomical homeostasis and reproduce. This leads to organ malfunction, diseases, and ultimately death. The traditional understanding of aging is that it is caused by the accumulation of molecular...

CD58 alterations govern antitumor immune responses by inducing PD-L1 and IDO in diffuse large B-cell lymphoma
Cancer Res. 2024 Apr 18. doi: 10.1158/0008-5472.CAN-23-2874. Online ahead of print.ABSTRACTRecurrent abnormalities in immune surveillance-related genes affect the progression of diffuse large B-cell lymphoma (DLBCL) and modulate the response to therapeutic interventions. CD58 interacts with the CD2 receptor on T cells and natural killer (NK) cells and is recurrently mutated and deleted in DLBCL, suggesting it may play a role in regulating antitumor immunity. Herein, we comprehensively analyzed the genomic characteristics of CD58 through targeted next-generation sequencing, RNA-sequencing, whole-exome sequencing, and single...

Fc-silent anti-TIGIT antibodies potentiate anti-tumor immunity without depleting regulatory T cells
Cancer Res. 2024 Apr 18. doi: 10.1158/0008-5472.CAN-23-2455. Online ahead of print.ABSTRACTTIGIT is an inhibitory receptor on immune cells that outcompetes an activating receptor, CD226, for shared ligands. Tumor-infiltrating lymphocytes express TIGIT and CD226 on regulatory T cells (Treg) and on CD8+ T cells with tumor-reactive or exhausted phenotypes, supporting the potential of therapeutically targeting TIGIT to enhance anti-tumor immunity. To optimize the efficacy of therapeutic antibodies against TIGIT, it is necessary to understand whether there is therapeutic benefit from Fcγ receptor (FcγR) binding. Here, we show...

CD106 in tumor-specific exhausted CD8+ T cells mediates immunosuppression by inhibiting TCR signaling
Cancer Res. 2024 Apr 18. doi: 10.1158/0008-5472.CAN-23-0453. Online ahead of print.ABSTRACTT cell exhaustion is a major contributor to immunosuppression in the tumor microenvironment (TME). Blockade of key regulators of T cell exhaustion, such as PD-1, can reinvigorate tumor-specific T cells and activate anti-tumor immunity in various types of cancer. Here, we identified that CD106 was specifically expressed in exhausted CD8+ T cells in the TME using single-cell RNA-sequencing. High CD106 expression in the TME in clinical samples corresponded to improved response to cancer immunotherapy. CD106 in tumor-specific T cells sup...

Omental preadipocytes stimulate matrix remodeling and IGF signaling to support ovarian cancer metastasis
Cancer Res. 2024 Apr 18. doi: 10.1158/0008-5472.CAN-23-2613. Online ahead of print.ABSTRACTOvarian cancer can metastasize to the omentum, which is associated with a complex tumor microenvironment. Omental stromal cells facilitate ovarian cancer colonization by secreting cytokines and growth factors. Improved understanding of the tumor supportive functions of specific cell populations in the omentum could identify strategies to prevent and treat ovarian cancer metastasis. Here, we showed that omental preadipocytes enhance the tumor initiation capacity of ovarian cancer cells. Secreted factors from preadipocytes supported ca...

Deuterium metabolic imaging differentiates glioblastoma metabolic subtypes and detects early response to chemoradiotherapy
Cancer Res. 2024 Apr 18. doi: 10.1158/0008-5472.CAN-23-2552. Online ahead of print.ABSTRACTMetabolic subtypes of glioblastoma have different prognoses and responses to treatment. Deuterium metabolic imaging with 2H-labeled substrates is a potential approach to stratify patients into metabolic subtypes for targeted treatment. Here, we used 2H magnetic resonance spectroscopy (MRS) and spectroscopic imaging (MRSI) measurements of [6,6'-2H2]glucose metabolism to identify metabolic subtypes and their responses to chemoradiotherapy in patient-derived glioblastoma xenografts in vivo. The metabolism of patient-derived cells was fi...

Hemisynthesis and cytotoxic evaluation of manoyl oxide analogs from sclareol: effect of two tertiary hydroxyls & amp; Heck coupling on cytotoxicity
Nat Prod Res. 2024 Apr 18:1-10. doi: 10.1080/14786419.2024.2342558. Online ahead of print.ABSTRACTSclareol, a bioactive diterpene alcohol isolated from Salvia sclarea, was subjected to structural modification and cytotoxic evaluation. Boron-Heck-coupled analogs of manoyl oxide were prepared from sclareol in a two-step reaction scheme. In the first step manoyl oxide was prepared from sclareol using cerium (IV) ammonium nitrate. Further the structural modification of manoyl oxide via Palladium (II) catalysed Boron-Heck coupling reaction produced a new series of compounds. All the synthesised compounds were screened for in vi...

Autophagy cooperates with PDGFRA to support oncogenic growth signaling
Autophagy. 2024 Apr 18:1-2. doi: 10.1080/15548627.2024.2338572. Online ahead of print.ABSTRACTMacroautophagy (referred to as autophagy hereafter) is a highly conserved catabolic process which sequesters intracellular substrates for lysosomal degradation. Autophagy-related proteins have been shown to be involved in various aspects of tumor development by engaging with multiple cellular substrates. We recently uncovered a novel role for autophagy in regulating the signaling and levels of PDGFRA, a receptor tyrosine kinase amplified in several cancers. We discovered that PDGFRA can be targeted to autophagic degradation by bin...

Gallbladder cancer: surgical treatment, immunotherapy, and targeted therapy
Postgrad Med. 2024 Apr 18. doi: 10.1080/00325481.2024.2345585. Online ahead of print.ABSTRACTGallbladder cancer is a common type of biliary tract tumor. Optimal management for early stage cases typically involves radical excision as the primary treatment modality. Various surgical techniques, including laparoscopic, robotic, and navigational surgery, have demonstrated favorable clinical outcomes in radical gallbladder excision. Unfortunately, most patients are ineligible for surgical intervention because of the advanced stage of the disease upon diagnosis. Consequently, non-surgical interventions, such as chemotherapy, rad...

Therapeutic Targeting of Thioredoxin Reductase 1 Causes Ferroptosis while Potentiating Anti-PD-1 Efficacy in Head and Neck Cancer
This study is the first to highlight TXNRD1 as a crucial factor contributing to resistance to anti-PD-1 treatment in HNSCC. In this study, we identified targetable regulators of resistance to immunotherapy-induced ferroptosis in HNSCC. We observed a link of thioredoxin reductase 1 (TXNRD1) with tumoral PD-L1 expression and ferroptosis suppression in HNSCC. Moreover, HNSCC tumors with aberrant TXNRD1 expression exhibited a lack of PD-1 response, NRF2 overexpression, and PD-L1 upregulation. TXNRD1 inhibition promoted ferroptosis in HNSCC cells with NRF2 activation and in organoid tumors derived from patients lacking a PD-1 r...
