Chromatin histone modifications and rigidity affect nuclear morphology independent of lamins

…, PZ Liu, EJ Banigan, LM Almassalha… - Molecular biology of …, 2018 - Am Soc Cell Biol
Nuclear shape and architecture influence gene localization, mechanotransduction, transcription,
and cell function. Abnormal nuclear morphology and protrusions termed “blebs” are …

Clostridium difficile Ribotype Does Not Predict Severe Infection

…, ES Lo, I Trivedi, EW Liu, LM Almassalha… - Clinical infectious …, 2012 - academic.oup.com
Background. Studies of Clostridium difficile outbreaks suggested that certain ribotypes (eg,

Physicochemical mechanotransduction alters nuclear shape and mechanics via heterochromatin formation

…, V Kandula, H Chen, LM Almassalha… - Molecular biology of …, 2019 - Am Soc Cell Biol
The nucleus houses, organizes, and protects chromatin to ensure genome integrity and
proper gene expression, but how the nucleus adapts mechanically to changes in the …

[HTML][HTML] Depletion of lamins B1 and B2 promotes chromatin mobility and induces differential gene expression by a mesoscale-motion-dependent mechanism

…, X Wei, N Acosta, LM Carter, J Yang, LM Almassalha… - Genome biology, 2024 - Springer
Background B-type lamins are critical nuclear envelope proteins that interact with the three-dimensional
genomic architecture. However, identifying the direct roles of B-lamins on …

The effects of chemical fixation on the cellular nanostructure

Y Li, LM Almassalha, JE Chandler, X Zhou… - Experimental cell …, 2017 - Elsevier
Chemical fixation is nearly indispensable in the biological sciences, especially in circumstances
where cryo-fixation is not applicable. While universally employed for the preservation of …

[HTML][HTML] The global relationship between chromatin physical topology, fractal structure, and gene expression

LM Almassalha, A Tiwari, PT Ruhoff, Y Stypula-Cyrus… - Scientific reports, 2017 - nature.com
