• Pre-existing immunity and hrHPV status as determinants of immunotherapy response in advanced penile cancer: biomarkers and overall survival in the PERICLES trial

  The phase II PERICLES trial (NCT03686332) investigated atezolizumab with or without radiotherapy in advanced penile cancer. Here, we report mature overall survival (OS) and updated progression-free survival (PFS) outcomes and an in-depth biomarker analysis. The goal was to perform an in-depth assessment of the tumor microenvironment to identify potential predictive biomarkers and cellular mechanisms underlying successful PD-L1 blockade response.

• NeoLetExe clinical trial single-cell RNA-seq, scTCR-seq, scBCR-seq and cis-regulatory elements mapping

  We performed single cell RNA sequencing, single cell T cell receptor and B cell receptor sequencing on breast tumor biopsies collected from patient of the NeoLetExe clinical trial at 3 time points of neoadjuvant therapy with aromatase inhibitors. The NeoLetExe study is a randomized open-label clinical trial aimed at evaluating the effects of sequential aromatase inhibition in postmenopausal women with ER-positive, HER-2 negative locally advanced breast cancer (stages T3-T4 and/or N2-3, including larger T2 tumors). Fresh tumor biopsies were dissociated at the single cell level which when then processed using the 10x Genomics Chromium platform, using the Single-Cell 5′ RNA-seq method along with single cell BCR and TCR-seq. The target was 7,500 to 10,000 cells per well, with libraries prepared using Gel Bead, Multiplex, and Chip Kits, following the manufacturer’s guidelines. Sequencing was performed on NovaSeq6000. We used SCAFE v1.0.065 to identify TSSs and map transcriptionally active regulatory elements.

• Cell-Free DNA Fragmentation Distinguish Immunotherapy Responders from Non- Responders in Head and Neck Cancer: A Multi-Institute Prospective Study

  We performed whole-genome sequencing of 185 plasma cfDNA samples from 68 patients with head and neck squamous cell carcinoma (HNSCC) enrolled in a phase II clinical trial of neoadjuvant and adjuvant pembrolizumab. Using these data, we developed the regional motif diversity score (rMDS), a novel fragmentomic biomarker that predicts immunotherapy response and outperforms established cfDNA metrics.

• Genetic, epigenetic and fragmentomic profiling of plasma cell-free DNA in cancer patients

  The primary goal of the study is to explore the temporal changes in cfDNA profiles in liver cancer patients undergoing therapeutic treatment. Serial blood collection and plasma cfDNA analysis were performed in patients with liver cancer, including patients with primary hepatocellular carcinoma, or those with secondary liver metastasis. Various molecular features of cfDNA were studied, including tumor fraction, epigenetic and fragmentomic analysis.

• Ex vivo therapy-driven selection of glioblastoma stem-like cells models resistance evolution

  Glioblastoma (GBM) remains lethal, creating an urgent need for experimental models of therapy- specific resistance evolution. Within-patient GSC models were developed by parallel ex-vivo selection under temozolomide (TMZ-GSC) or ionizing radiation (IR-GSC), alongside untreated controls (CTRL- GSC). • O6-methylguanine-DNA methyltransferase (MGMT) expression was confirmed as a determinant of primary TMZ resistance and was maintained during GSC evolution. • In MGMT-negative GSCs, primary TMZ sensitivity evolved into stable secondary resistance through mismatch-repair gene inactivation, recapitulating patient findings, or was retained along with a newly identified drug-tolerant phenotype. • Primary radioresistance was commonly observed, while its further evolution was associated with more efficient DNA double-strand-break repair and enrichment of homologous- recombination and checkpoint-control transcriptional programs. • In GSCs emerging after either TMZ or IR, broad transcriptional patient-specific programs and classification-relevant subtypes were largely preserved. • Across treatments, GSC evolution was accompanied by shared genome-maintenance and mitotic chromosome-segregation transcriptional programs and increased RTK expression and activity, collectively promoting recovery after genotoxic stress.

• Genetic, epigenetic and fragmentomic profiling of plasma cell-free DNA in cancer patients

  The uploaded data includes sequencing of plasma cfDNA from a total of 33 cancer patients. Plasma cfDNA samples were sequenced for whole-genome sequencing analysis using double-stranded DNA libraries, and paired bisulfite sequencing using single-stranded DNA libraries. All sequencing data are of extracted plasma cfDNA from human patients, and sequenced using the Illumina NovaSeq6000 platform. Alignment was performed to the human genome (hg19). Lambda DNA was added to samples subjected to bisulfite sequencing for quality control.

• Nicotinamide phosphoribosyltransferase is an integrator of circadian clock regulation and NAD+ metabolism in liver cancer

  NAMPT is a liver-specific integrator of circadian and metabolic regulation, and its dysregulation creates a therapeutic window for a more precise treatment of liver cancer.

• The Precision Medicine in Liver Cancer across an Asia-pacific NETwork (PLANET) – HCC recurrence cohort

  Hepatocellular carcinoma (HCC) is a highly fatal cancer marked by significant intra-tumor heterogeneity (ITH). Given 50% to 70% of HCC patients experience recurrence, understanding the origins and progression of recurrence is crucial. To address this, we assembled a multi-sector, paired HCC recurrence cohort of 24 patients, including comprehensive whole genome sequencing and transcriptome samples. Through this longitudinal cohort, we aimed to trace the origins of recurrence and identify molecular features associated with early recurrence. These insights may improve predictions of early HCC recurrence and inform potential therapeutic strategies.
