GSLR Drives Lung Adenocarcinoma as a Critical Regulator of Energy Homeostasis Through Creatine Kinase B Activation

open access: yesAdvanced Science, EarlyView.
This study identifies the glucose/glutamine sensitive lncRNA GSLR as a driver of lung adenocarcinoma progression. Nutrient restriction reduces chromatin accessibility at the GSLR locus and blocks CTCF‐mediated transcriptional regulation. GSLR directly interacts with DHX9 and recruits it to the CKB promoter, arresting R‐loop accumulation and promoting ...

Disentangling Heterogeneous Molecular Networks for Multi‐Omics‐Driven Cancer Driver Discovery

open access: yesAdvanced Science, EarlyView.
DRIVE integrates PPI topology and pan‐cancer multi‐omics profiles through dual‐view graph disentanglement, contrastive representation learning, and joint optimization. Across six PPI networks, DRIVE outperforms ten baselines and remains robust to structural and annotation perturbations.

Transfer RNA‐Derived Small RNA‐5’tiRNAGln Drives HNRNPC Phase Separation to Promote Breast Cancer Bone Metastasis by Regulating IGF1R

open access: yesAdvanced Science, EarlyView.
This study reveals that 5'tiRNA‐Gln interacts with hnRNPC to promote IGF1R liquid‐liquid phase separation, which drives ERK1/2 signaling activation, EMT, and breast cancer bone metastasis. These findings highlight a novel mechanism of breast cancer bone metastasis and potential therapeutic target in metastatic breast cancer.

Axial contraction and short-range compaction of chromatin synergistically promote mitotic chromosome condensation

open access: yeseLife, 2015
The segregation of eukaryotic chromosomes during mitosis requires their extensive folding into units of manageable size for the mitotic spindle. Here, we report on how phosphorylation at serine 10 of histone H3 (H3 S10) contributes to this process. Using

Relocation of Aurora B from centromeres to the central spindle at the metaphase to anaphase transition requires MKlp2 [PDF]

open access: yes, 2004
Mitotic kinases of the Polo and Aurora families are key regulators of chromosome segregation and cytokinesis. Here, we have investigated the role of MKlp1 and MKlp2, two vertebrate mitotic kinesins essential for cytokinesis, in the spatial regulation of ...

Decoding Biomolecular Phase Separation: From Physiological Roles to Pathological Mechanisms and Therapeutic Biomaterials Design

open access: yesAdvanced Science, EarlyView.
This review systematically elaborates on the mechanisms underlying physiological regulation and pathological dysregulation of biomolecular phase separation. It also summarizes advances in phase‑separation‑targeted therapeutic strategies and the design of functional biomaterials inspired by this process.

Determination of Gene‐Level Fitness Contributions Across the Mucin‐Utilization Network of Bacteroides thetaiotaomicron

open access: yesAdvanced Science, EarlyView.
Genome‐wide CRISPRi and RNA‐seq resolve how B. thetaiotaomicron converts host mucosal glycans into fitness. The study reveals a layered mucin‐utilization architecture in which capsular polysaccharides constrain surface access, extracellular CAZymes and peptidases show functional redundancy, and intracellular catabolic pathways create discrete metabolic

SEC Mediates m6A Deposition and Transcription Pause Release to Drive Cell Identity Transition

open access: yesAdvanced Science, EarlyView.
The SEC promotes cell identity transitions by facilitating transcription pause release at key identity‐associated genes, including Klf4 and Myc during iPSC reprogramming and Nes and Tubb3 during ESC‐to‐neuroectodermal differentiation. During early iPSC reprogramming, this function additionally involves cooperation with METTL3‐associated m6A regulation.

A Living Multi‐Omics PDX Biobank of High‐Risk Sarcomas Reveals ecDNA‐Driven Oncogene Amplification in Osteosarcoma and Enables Preclinical Precision Oncology

open access: yesAdvanced Science, EarlyView.
A living multi‐omics sarcoma PDX biobank is enriched for high‐risk disease and preserves key patient tumor features at histopathological and molecular levels. Integrated profiling reveals ecDNA‐driven oncogene amplification in osteosarcoma and preferential retention of ecDNA during PDX evolution.

NuSAP4 regulates chromosome segregation in Trypanosoma brucei by promoting bipolar spindle assembly

open access: yesCommunications Biology
Faithful chromosome segregation in eukaryotes requires the assembly of a bipolar spindle and the faithful attachment of kinetochores to spindle microtubules, which are regulated by various spindle-associated proteins (SAPs) that play distinct functions ...
