RNA‐related functions of BRCA2 in transcription, replication, and genome stability

open access: yesFEBS Letters, EarlyView.
Beyond its role in homologous recombination, BRCA2 regulates R‐loop homeostasis, DNA–RNA hybrid resolution, RNA polymerase II dynamics, and transcriptional activation. Disruption of any of these functions can contribute to genome instability, inflammatory signaling, and tumorigenesis. BRCA2 is a central tumor suppressor protein best known for its roles

Relativism and Persistence [PDF]

open access: yesPhilosophical Studies, 1997
[FIRST PARAGRAPHS] Philosophers often talk as if what it takes for a person to persist through time were up to us,\ud as individuals or as a linguistic community, to decide. In most ordinary situations it might be\ud fully determinate whether someone has survived or perished: barring some unforeseen\ud catastrophe, it is clear enough that you will ...

Metronidazole-tolerant Porphyromonas gingivalis persisters dampen cytokine expression in HGECs

open access: yes, 2019
Objectives: Our group has recently demonstrated the existence of metronidazole-tolerant Porphyromonas gingivalis persisters. This study further investigated the effects of P.

Artificial molecular machines and motors—Design and control of nanoscale motion

open access: yesFEBS Letters, EarlyView.
Molecules are constantly moving because of thermal fluctuations, but random motion alone cannot be exploited to perform directional tasks. Artificial molecular machines use chemical, electrical, or light energy to bias this motion. Molecular shuttles, rotary motors, and supramolecular pumps illustrate how nanoscale movement can be controlled and ...

Enhanced antibiotic resistance development from fluoroquinolone persisters after a single exposure to antibiotic

open access: yesNature Communications, 2019
Fluoroquinolone (FQ)-induced DNA damage in persisters could promote antibiotic resistance. Here, using time-lapse microscopy and genetic analyses, the authors show that after a single round of FQ treatment, SOS response in persisters accelerates the ...

A context‐dependent modulatory role for eIF6 in acquired resistance to vemurafenib in melanoma

open access: yesFEBS Letters, EarlyView.
Acquired resistance to vemurafenib upregulates the translation factor eIF6 in melanoma cells. Silencing eIF6 in resistant cells reduces proliferation and partially restores drug sensitivity, whereas its overexpression increases sensitivity across melanoma lines regardless of BRAF status, via modulation of mTOR, S6K, and MAPK signaling.

Persistent Mayer homology and persistent Mayer Laplacian

open access: yesFoundations of Data Science
In algebraic topology, the differential (i.e., boundary operator) typically satisfies $d^{2}=0$. However, the generalized differential $d^{N}=0$ for an integer $N\geq 2$ has been studied in terms of Mayer homology on $N$-chain complexes for more than eighty years. We introduce Mayer Laplacians on $N$-chain complexes.

The ubiquitin system in normal and infected germinal center B cells

open access: yesFEBS Letters, EarlyView.
The ubiquitin system plays a central role in germinal center (GC) B cells, influencing differentiation to long‐lived memory B cells. Oncogenic gammaherpesviruses gain access to memory B cells by establishing latency in GC B cells. Mapping ubiquitin mechanisms in normal and infected GC B cells will define specific molecular circuits in B cells germane ...

The survival mechanisms underlying caspofungin-induced Candida albicans biofilm persisters

open access: yes, 2015
OBJECTIVES: Candida infection has increasingly posed a threat to oral and systemic health worldwide, due to formation of robust biofilms against high concentrations of antifungals.
