A study of CIS-acting elements required for dosage compensation in Drosophila Melanogaster : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Genetics at Massey University, Palmerston North, New Zealand [PDF]
, 2000 Dosage compensation (the equalisation of X-linked gene products) occurs in Drosophila melanogaster by a two fold transcriptional up-regulation of X-linked gene expression in males. This involves the binding of five proteins, MSL-1, MSL-2, MSL-3, MLE, MOF,

Understanding how chromatin folding and enzyme competition affect rugged epigenetic landscapes [PDF]
arXivEpigenetics plays a key role in cellular differentiation and maintaining cell identity, enabling cells to regulate their genetic activity without altering the DNA sequence. Epigenetic regulation occurs within the context of hierarchically folded chromatin, yet the interplay between the dynamics of epigenetic modifications and chromatin architecture ...

Advanced Science, EarlyView.These findings elucidate the innovative role of HIC1 as a transcriptional activator in GC, driving the initiation of pyroptosis and enhancing CD8+ T cell infiltration, which has certain novelty and creative significance. Collectively, targeting HIC1 can present an appealing immunotherapeutic strategy to improve outcomes in GC patients.

Single-substrate Enzyme Kinetics: The Quasi-steady-state Approximation and Beyond [PDF]
J. Math. Chem. 51 (2013) 1467, 2012 We analyze the standard model of enzyme-catalyzed reactions at various substrate-enzyme ratios to identify the regions of validity of the quasi-steady-state approximation. Certain prevalent conditions are checked and compared against the actual findings. Efficacies of a few other measures are highlighted. Some very recent observations are rationalized,

IncRNA‐ZFAS1, an Emerging Gate‐Keeper in DNA Damage‐Dependent Transcriptional Regulation
Advanced Science, EarlyView.LncZFAS1 plays a crucial role during DNA damage response in mammalian cells. Loss of lncZFAS1 results in deficient DNA lesion removal and reduced cell viability. Mechanistically, lncZFAS1 modulates RNAPII phosphorylation and transcription and thereby promotes both GG‐NER and TC‐NER upon UV damage.

Effective inter-symbol interference mitigation with a limited amount of enzymes in molecular communications [PDF]
arXiv, 2016 In molecular communication via diffusion (MCvD), the inter-symbol interference (ISI) is a well known severe problem that deteriorates both data rates and link reliability. ISI mainly occurs due to the slow and highly random propagation of the messenger molecules, which causes the emitted molecules from the previous symbols to interfere with molecules ...
