Biomedical research published between October 21 and October 23, 2026, includes a first-in-human trial of the PfSPZ-LARC2 malaria vaccine in 75 Burkinabe participants, which reported a safety profile comparable to placebo. Other findings include a genome-wide scan of 2,236 ancient East Asian genomes identifying genetic variants linked to the transition to agriculture and a study on the transcription factor BRN2, which preserves melanocyte stem cells after ionizing radiation. Researchers also identified sex-specific molecular programs in muscle-invasive bladder cancer, noting distinct DNA methylation patterns in male and female tumors. Additionally, a study on the small-molecule inhibitor ERG344 demonstrated that targeting ACOD1 can attenuate colitis and tumor growth by modulating myeloid cell dynamics. These studies were published across various bioRxiv and medRxiv channels covering infectious disease, cancer immunology, and molecular mechanisms. Synthesized from 499 manifests produced by 28 monitored biomedical research sources in the last 7 days, including bioRxiv, medRxiv, HHS.

Ancient genomes chronicle the history of adaptive evolution in East Asia
Researchers performed a genome-wide scan on 2,236 ancient East Asian genomes to reconstruct the timeline and spatial distribution of adaptive genetic variants. By correlating these variants with archaeobotanical data from 1,220 sites, the study identifies specific loci-including ADH1B, FADS1, FUT2, and OCA2-that underw
Small-molecule ACOD1 inhibition attenuates colitis and tumor growth through a shared myeloid mechanism, diverging from genetic deletion
Pharmacological inhibition of ACOD1 using ERG344 provides a novel therapeutic strategy for colitis and cancer, distinct from the outcomes observed in genetic ACOD1-deficient models. The study demonstrates that ERG344 modulates myeloid cell dynamics, specifically reducing immature monocyte influx and promoting mature ne
BRN2 preserves the melanocyte lineage following ionizing radiation
Researchers have identified the transcription factor BRN2 (POU3F2) as a key regulator of melanocyte stem cell (McSC) integrity under stress. While BRN2 is not required for steady-state maintenance, its absence leads to rapid, permanent loss of McSCs and hair depigmentation following ionizing radiation. The study furthe
First-in-human trial in Burkinabe adults and children of replication-competent, genetically attenuated PfSPZ-LARC2 Vaccine for malaria
The PfSPZ-LARC2 vaccine, a genetically attenuated whole-parasite malaria vaccine, successfully completed a first-in-human trial in Burkina Faso. The study involved 75 participants aged 1-48 years and reported no vaccine-strain breakthrough infections with a safety profile comparable to placebo. These results support th
Sex Differences in DNA Methylation and Gene Expression Reveal Distinct Molecular Programs in Muscle-Invasive Bladder Cancer
This study characterizes sex-specific molecular landscapes in muscle-invasive bladder cancer (MIBC), revealing that male tumors undergo broader DNA methylation remodeling while female tumors exhibit distinct EMT and mitotic signatures. By integrating human data with the BBN mouse model, the researchers identified conse
