A Model of Epigenetic Inheritance Accounts for Unexpected Adaptation to Unforeseen Challenges

Advanced Science, EarlyView.
A general model of inheriting changes that are acquired during the lifetime of individuals demonstrates tremendous benefits to the population, including escape from extinction in changing environments. Contrasting the model with experimental data shows that inheritance of acquired changes enables rapid adaptation to unforeseen challenges, and accounts ...

Contrasting determinants of mutation rates in germline and soma [PDF]

Genetics, 2017
AbstractRecent studies of somatic and germline mutations have led to the identification of a number of factors that influence point mutation rates, including CpG methylation, expression levels, replication timing and GC content. Intriguingly, some of the effects appear to differ between soma and germline: in particular, whereas mutation rates have been

A theoretical model of soma-to-germline transmission of transposable elements to build new gene regulatory sequences [PDF]

arXiv, 2015
Transposable elements are DNA sequences that can move around to different positions in the genome. During this process, they can cause mutations, and lead to an increase in genome size. Despite representing a large genomic fraction, transposable elements have no clear biological function. This work builds upon a previous model, to propose a new concept

Long mutation cycles [PDF]

arXiv, 2023
A mutation cycle is a cycle in a graph whose vertices are labeled by the quivers in a given mutation class and whose edges correspond to single mutations. For any fixed $n\ge 4$, we describe arbitrarily long mutation cycles involving $n$-vertex quivers.

A Versatile High‐Throughput Single‐Cell Screening Platform for Profiling Antigen‐Specific Long‐Lived B Cells in Blood and Bone Marrow

Advanced Science, EarlyView.
The MoSMAR‐chip platform provides a high‐throughput and cost‐effective tool for identifying and characterizing antigen‐specific antibody‐secreting cells (ASCs) and memory B cells (MBCs) at the single‐cell level. The ASCs from coronavirus disease 2019 (COVID‐19) vaccine‐immunized mice were successfully analyzed, revealing diverse neutralizing antibodies

Bayesian Combinatorial Multi-Study Factor Analysis [PDF]

arXiv, 2020
Analyzing multiple studies allows leveraging data from a range of sources and populations, but until recently, there have been limited methodologies to approach the joint unsupervised analysis of multiple high-dimensional studies. A recent method, Bayesian Multi-Study Factor Analysis (BMSFA), identifies latent factors common to all studies, as well as ...

RAB3B Dictates mTORC1/S6 Signaling in Chordoma and Predicts Response to mTORC1‐Targeted Therapy

Advanced Science, EarlyView.
RAB3B is unveiled as a prominent oncogenic regulator in chordoma, which can block the DUSP12‐mediated dephosphorylation of p‐S6 (S235/236). The combination of RAB3B and p‐S6 indicates a good prognostic value and predicts mTORC1 inhibitors response for chordoma patients.

European guidelines from the EHTG and ESCP for Lynch syndrome: an updated third edition of the Mallorca guidelines based on gene and gender

BJS (British Journal of Surgery), EarlyView., 2020
Recommendations for clinical and molecular identification of LS, surgical and endoscopic management of LS‐associated colorectal cancer and preventive measures for cancer were produced. The emphasis was on surgical and gastroenterological aspects of the cancer spectrum.

The phenotype of SDHB germline mutation carriers: a nationwide study [PDF]

European Journal of Endocrinology, 2017
Objective Succinate dehydrogenase B subunit (SDHB) gene germline mutations predispose to pheochromocytomas, sympathetic paragangliomas, head and neck paragangliomas and non-paraganglionic tumors (e.g. renal cell carcinoma, gastrointestinal stromal tumor and pituitary neoplasia).

Plac1+ Tumor Cell‐Treg Interplay Supports Tumorigenesis and Progression of Head and Neck Cancer

Advanced Science, EarlyView.
Meng et al. screen genes in the CTAs family and find Plac1 is specifically expressed in head and neck squamous cell carcinoma (HNSCC) cells. They reveal that Plac1 expression promotes HNSCC progression directly by activating PI3K/AKT signaling pathway.
