AI Article Synopsis
- LEA proteins help organisms survive extreme dryness, and the larvae of the African chironomid Polypedilum vanderplanki can tolerate nearly complete desiccation by entering suspended animation.
- Researchers isolated three cDNAs (PvLEA1, PvLEA2, and PvLEA3) from these larvae, which are linked to Group 3 LEA proteins and showed increased expression under dehydration stress.
- The findings indicate that LEA proteins are common in invertebrates and highlight a shared strategy among animals, plants, and microorganisms to handle dehydration.
Article Abstract
Late embryogenesis abundant (LEA) proteins are associated with desiccation tolerance in anhydrobiotic organisms. The larvae of an African chironomid, Polypedilum vanderplanki, are able to withstand almost complete desiccation during which they enter a state of suspended animation. Here, we developed an EST database from desiccating larvae and isolated three cDNAs encoding proteins (PvLEA1, PvLEA2, and PvLEA3) with highly significant matches to Group 3 LEA proteins. Both mRNA and protein levels of all three examples were increased by dehydration stress imposed by either desiccation or hypersalinity, and one protein, PvLEA2, is likely to be post-translationally processed into smaller molecules. This first description of LEA protein genes in arthropods suggests that this protein family is widespread throughout invertebrate phyla, and that animals, plants, and microorganisms possess similar mechanisms for combating dehydration stress.

() genes play a crucial role in the response to abiotic stress and are important target genes for research on plant stress tolerance mechanisms. Bunge is a promising candidate tree species for investigating the tolerance mechanism of woody plants against abiotic stress. In our previous study, was identified as being associated with seed drought tolerance.

We aim to understand the host immunologic and microbial features of COVID-19 in transplant recipients by leveraging a prospective multicenter cohort of 86 transplant recipients age- and sex-matched with 172 non-transplant controls. We find that transplant recipients have higher nasal SARS-CoV-2 viral abundance and impaired viral clearance, and lower anti-spike IgG levels.

Background: Familial Mediterranean fever (FMF) is the most common monogenic autoinflammatory disease, associated with MEFV mutations. FMF patients can experience liver involvement, potentially leading to cirrhosis.
Objectives: This study aimed to evaluate liver involvement in FMF patients at a French tertiary centre for adult FMF.
Article Synopsis
- PAX2 is identified as an endometrial tumor suppressor frequently inactivated through a unique epigenetic mechanism, rather than promoter hypermethylation.
- In 80% of endometrial cancers, the loss of PAX2 is linked to transcriptional silencing, which alters chromatin features, contributing to cancer development.
- The research highlights new pathways for understanding endometrial cancer origins, potentially influencing future diagnosis and treatment approaches.
Evaluation of the hematological parameters, inflammatory biomarkers, and thyroid hormones in hypothyroidism patients.

Aim: Hypothyroidism is created by disruption of thyroid hormone production, which can destroy the emotional, relational, social, and working life of patients if left untreated. Hypothyroidism has multiple etiologies. We evaluated the relationship of hematological parameters and inflammatory biomarkers with thyroid hormones to find the potential use of these items in patients screening and prognosis.
