Insertional DNA and spontaneous mutation at the white locus in Drosophila simulans

Molecular and General Genetics MGG, 1987
A large body of data on molecular analyses of several multiallelic loci in Drosophila melanogaster has demonstrated a high incidence of mobile DNA element insertions among spontaneous mutations. In the sibling species D. simulans, the dispersed, middle repetitive, nomadic sequences are reduced to about one-seventh that of its sibling species (Dowsett ...

Somatic mutations of esophageal adenocarcinoma: a comparison between Black and White patients

Scientific Reports, 2023
Abstract Esophageal adenocarcinoma is the most common histological subtype of esophageal cancer in Western countries and shows poor prognosis with rapid growth. EAC is characterized by a strong male predominance and racial disparity. EAC is up to five-fold more common among Whites than Blacks, yet Black patients with EAC have poorer survival ...

Surfaceome: a new era in the discovery of immune evasion mechanisms of circulating tumor cells

Molecular Oncology, EarlyView.
In the era of immunotherapies, many patients either do not respond or eventually develop resistance. We propose to pave the way for proteomic analysis of surface‐expressed proteins called surfaceome, of circulating tumor cells. This approach seeks to identify immune evasion mechanisms and discover potential therapeutic targets. Circulating tumor cells (

Local asymptotic stability of a system of integro-differential equations describing clonal evolution of a self-renewing cell population under mutation [PDF]

arXiv, 2020
In this paper we consider a system of non-linear integro-differential equations (IDEs) describing evolution of a clonally heterogeneous population of malignant white blood cells (leukemic cells) undergoing mutation and clonal selection. We prove existence and uniqueness of non-trivial steady states and study their asymptotic stability.

Molecular lesions associated with white gene mutations induced by I-R hybrid dysgenesis in Drosophila melanogaster [PDF]

, 1984
We have identified molecular lesions associated with six mutations, w(IR2) and w(IR4-8), of the white gene of Drosophila melanogaster. These mutations arose in flies subject to I-R hybrid dysgenesis.

Genetic Dissection of the Drosophila Nervous System by means of Mosaics [PDF]

, 1970
Given a mutant having abnormal behavior, the anatomical domain responsible for the deficit may be identified by the use of genetic mosaicism. Individuals may be produced in which a portion of the body is mutant male while the rest is normal female.

Clinical applications of next‐generation sequencing‐based ctDNA analyses in breast cancer: defining treatment targets and dynamic changes during disease progression

Molecular Oncology, EarlyView.
Circulating tumor DNA (ctDNA) offers a possibility for different applications in early and late stage breast cancer management. In early breast cancer tumor informed approaches are increasingly used for detecting molecular residual disease (MRD) and early recurrence. In advanced stage, ctDNA provides a possibility for monitoring disease progression and

A Spatial Mutation Model with Increasing Mutation Rates [PDF]

arXiv, 2021
We consider a spatial model of cancer in which cells are points on the $d$-dimensional torus $\mathcal{T}=[0,L]^d$, and each cell with $k-1$ mutations acquires a $k$th mutation at rate $\mu_k$. We will assume that the mutation rates $\mu_k$ are increasing, and we find the asymptotic waiting time for the first cell to acquire $k$ mutations as the torus ...

Circulating tumor DNA (ctDNA) trajectories predict survival in trifluridine/tipiracil‐treated metastatic colorectal cancer patients

Molecular Oncology, EarlyView.
The authors applied joint/mixed models that predict mortality of trifluridine/tipiracil‐treated metastatic colorectal cancer patients based on circulating tumor DNA (ctDNA) trajectories. Patients at high risk of death could be spared aggressive therapy with the prospect of a higher quality of life in their remaining lifetime, whereas patients with a ...
