Structural and mechanistic basis for the regulation of the chloroplast signal recognition particle by (p)ppGpp

open access: yesFEBS Letters, EarlyView.
LHCPs are transported to the thylakoid membrane via the (cp)SRP pathway. This process involves a transit complex of (cp)SRP43, (cp)SRP54 and LHCP, which interacts with (cp)FtsY and Alb3 at the membrane. GTP hydrolysis by (cp)SRP54 and (cp)FtsY triggers complex dissociation.

Modelling the order of driver mutations and metabolic mutations as structures in cancer dynamics [PDF]

open access: yesarXiv, 2017
Recent works have stressed the important role that random mutations have in the development of cancer phenotype. We challenge this current view by means of bioinformatic data analysis and computational modelling approaches. Not all the mutations are equally important for the development of metastasis.

Distinct dysregulated pathways in sporadic and Lynch syndrome‐associated colorectal cancer offer insights for targeted treatment

open access: yesFEBS Letters, EarlyView.
This study explores the distinct molecular mechanisms underlying Lynch syndrome‐associated and sporadic colorectal cancer (CRC). By highlighting the therapeutic potential of targeting the PI3K‐Akt pathway in Lynch syndrome‐associated CRC and the Wnt pathway in sporadic CRC, the findings open avenues for personalised treatment strategies, aiming to ...

Potent dual block to HIV-1 infection using lentiviral vectors expressing fusion inhibitor peptide mC46- and Vif-resistant APOBEC3G

open access: yesMolecular Therapy: Nucleic Acids, 2023
Gene therapy strategies that effectively inhibit HIV-1 replication are needed to reduce the requirement for lifelong antiviral therapy and potentially achieve a functional cure.

Interference effects of deleterious and beneficial mutations in large asexual populations [PDF]

open access: yesGenetics 211, 1357-1369 (2019), 2018
Linked beneficial and deleterious mutations are known to decrease the fixation probability of a favorable mutation in large asexual populations. While the hindering effect of strongly deleterious mutations on adaptive evolution has been well studied, how weak deleterious mutations, either in isolation or with superior beneficial mutations, influence ...

Immunoregulatory mechanisms of the arachidonic acid pathway in cancer

open access: yesFEBS Letters, EarlyView.
The central role of the arachidonic acid (AA) pathway in anticancer immunity. Enzymes and metabolites of the AA pathway can play both immunosuppressive and immunostimulatory roles in the tumor microenvironment. Therefore, their tailored targeting could be beneficial as a standalone therapy or in combination with current cancer immunotherapy.

Lack of Detection of Xenotropic Murine Leukemia Virus-Related Virus in HIV-1 Lymphoma Patients

open access: yesAdvances in Virology, 2011
Xenotropic murine leukemia virus-related virus (XMRV) is a gammaretrovirus reported to be associated with human prostate cancer and chronic fatigue syndrome. Since retroviruses cause various cancers, and XMRV replication might be facilitated by HIV-1 co-

Fixation probability of rare nonmutator and evolution of mutation rates [PDF]

open access: yesEcology and Evolution 6, 755-764 (2016), 2015
Although mutations drive the evolutionary process, the rates at which the mutations occur are themselves subject to evolutionary forces. Our purpose here is to understand the role of selection and random genetic drift in the evolution of mutation rates, and we address this question in asexual populations at mutation-selection equilibrium neglecting ...

Taurine promotes glucagon‐like peptide‐1 secretion in enteroendocrine L cells

open access: yesFEBS Letters, EarlyView.
Taurine, a sulfur‐containing amino acid, is likely taken up by enteroendocrine L cells via the taurine transporter. This process increases the levels of cytosolic ATP. The increase in intracellular Ca2+ concentrations and glucagon‐like peptide‐1 secretion through membrane depolarization is caused by the closure of ATP‐sensitive potassium channels ...
