Nuclear mitochondrial DNA segments (NUMTs), which are mitochondrial DNA fragments integrated into the nuclear genome, serve as markers of evolutionary history. This study aims to enhance the detection and analysis of NUMTs by developing a script named NUMTsearcher. Utilizing the latest chromosome-level genome assemblies from various species, including human, rabbit, and six fish species, the study compares NUMTsearcher's performance against traditional methods such as LAST (Local Alignment Search Tool), BLAST (Basic Local Alignment Search Tool), BLAT (BLAST-Like Alignment Tool), and the pan-mitogenome approach, which integrates mitogenomes from diverse sources to identify fixed NUMTs in the nuclear genome.

Embryonic stem cells (ESCs), which are susceptible to DNA damage, depend on a robust and highly efficient DNA damage response (DDR) mechanism for their survival. However, the implications of physical force-mediated DNA damage on ESC fate remain unclear. We show that stiffness-dependent spreading of mouse ESCs (mESCs) induces DNA damage through nuclear compression, with DNA damage causing differentiation through Lamin A/C.

However, the prognostic significance of concurrent molecular abnormalities and clinical features in NPM1-mutated AML remains to be fully elucidated.
Methods: We retrospectively analyzed 73 adult AML patients with NPM1 mutations.

Immune checkpoint inhibitors (ICIs) can re-active the immune response and induce a complete response in mismatch repair-deficient and microsatellite instability-high (dMMR/MSI-H) colorectal cancer (CRC). However, most CRCs exhibit proficient mismatch repair and microsatellite stable (pMMR/MSS) phenotypes with limited immunotherapy response because of sparse intratumoral CD8 T-lymphocyte infiltration. Cellular senescence has been reported to involve immune cell infiltration through a senescence-associated secretory phenotype (SASP).

Living organisms have been exposed to ionizing radiation throughout Earth's 4-billion-year history, with humans presently receiving about 2 mSv of ionizing radiation every year. While radiation generates reactive oxygen and nitrogen species (ROS and RNS), organisms have evolved mechanisms to neutralize these toxic molecules and utilize them as signal transducers. High doses of radiation are harmful, but low doses are seemingly essential, and moderate doses can provide benefits-a phenomenon known as hormesis.
