Complete mitochondrial genome and draft chloroplastic genome of (Simonsen 1974).

The first completed, circular mitochondrial genome and the first draft, linear chloroplastic genome of the blue diatom (Simonsen 1974, ) were assembled from Illumina and PacBio sequencing. The mitochondrial genome was composed of 38,696 bases and contained 64 genes, including 31 protein-coding genes (CDS), 2 ribosomal RNA (rRNA) genes and 23 transfer RNA (tRNA) genes. For the chloroplast, the genome was composed of 130,200 bases with 169 genes (131 CDS, 6 rRNA genes, 31 tRNA genes, and 1 transfer messenger RNA gene).

Association between rs3732378 polymorphism and neovascular age-related macular degeneration in a sample of Algerian population.

Neovascular age-related macular degeneration (nAMD) is a progressive ocular disease, responsible for central visual loss and blindness in elderly population. Increase data demonstrate that genetic factors play an important role in pathogenesis process of this disease. The aim of this study is to investigate the association between rs3732378 polymorphism in gene and nAMD in a sample of Algerian patients.

Pigment Marennine Affects Key Actors of Neuroinflammation and Decreases Cell Migration in Murine Neuroglial Cell Model.

, a cosmopolitan marine pennate diatom, produces a characteristic blue pigment called marennine that causes the greening of filter-feeding organisms, such as oysters. Previous studies evidenced various biological activities of purified marennine extract, such as antibacterial, antioxidant and antiproliferative effects. These effects could be beneficial to human health.

Analysis of vascular endothelial growth factor (VEGF) insertion/deletion gene polymorphism and environmental risk factors in sample of Algerian population with neovascular age-related macular degeneration (nAMD).

Background: Increasing evidence shows that genetic and environmental factors can influence neovascular age-related macular degeneration (nAMD) risk. The aim of this study was first to analyse the association of insertion/deletion polymorphism in VEGF gene and environmental factors with the risk of nAMD, and then to investigate whether these factors have an impact on the age of onset of nAMD in a sample of the Algerian population.

Methods: Seventy two patients with nAMD and one hundred twenty-four controls were recruited; standardized questionnaire was used to collect information regarding underlying systemic diseases and important environmental factors.

Characterization of polymorphisms in and genes and their association with exudative age-related macular degeneration in Algerian patients.

Increasing evidence shows that polymorphisms in and genes can influence exudative age-related macular degeneration (nAMD) risk. The aim of this study was to assess the role of rs10033900 and rs3750846 polymorphisms in susceptibility to nAMD for the first time in the Algerian population. A total of one hundred twenty four controls and seventy two nAMD cases were included in the present study.

Contribution of n-3 Long-Chain Polyunsaturated Fatty Acids to the Prevention of Breast Cancer Risk Factors.

Nowadays, diet and breast cancer are studied at different levels, particularly in tumor prevention and progression. Thus, the molecular mechanisms leading to better knowledge are deciphered with a higher precision. Among the molecules implicated in a preventive and anti-progressive way, n-3 long chain polyunsaturated fatty acids (n-3 LC-PUFAs) are good candidates.

What Was Old Is New Again: The Pennate Diatom (Gaillon) Simonsen in the Multi-Omic Age.

The marine pennate diatom has long been known for its characteristic blue pigment marennine, which is responsible for the greening of invertebrate gills, a natural phenomenon of great importance for the oyster industry. For two centuries, this taxon was considered unique; however, the recent description of a new blue species revealed unsuspected biodiversity. Marennine-like pigments are natural blue dyes that display various biological activities-e.

Fucoxanthin, a Marine-Derived Carotenoid from Brown Seaweeds and Microalgae: A Promising Bioactive Compound for Cancer Therapy.

Fucoxanthin is a well-known carotenoid of the xanthophyll family, mainly produced by marine organisms such as the macroalgae of the fucus genus or microalgae such as . Fucoxanthin has antioxidant and anti-inflammatory properties but also several anticancer effects. Fucoxanthin induces cell growth arrest, apoptosis, and/or autophagy in several cancer cell lines as well as in animal models of cancer.

In Silico Study of Correlation between Missense Variations of Gene and Inhibitor Formation in Severe Hemophilia A.

Objective: Deleterious substitutions of the gene are responsible for causing hemophilia A, which is an inherited bleeding disorder resulting from reduced or absent activity of the coagulant protein factor VIII (FVIII). The most important complication in treatment is inhibitor development toward therapeutic factor VIII. In this study, we aimed to analyze the effects of deleterious substitutions in the gene upon protein structure and function.

TP53 Arg 72Pro and MDM2 SNP309 polymorphisms and colorectal cancer risk: a west Algerian population study.

The tumor suppressor gene TP53 and its regulator MDM2 are both key players involved in multiple pathways including apoptosis, cellular transcriptional control and cell cycle regulation. Common germline polymorphisms in these genes may affect colorectal cancer (CRC) susceptibility. An arginine-to-proline substitution at codon 72 in the TP53 gene is reported to decrease apoptotic potential, while a thymine-to-guanine polymorphism at nucleotide 309 (named SNP309) of murine double minute 2 MDM2 gene increases its transcription.

No association between XRCC3 Thr241Met and XPD Lys751Gln polymorphisms and the risk of colorectal cancer in West Algerian population: a case-control study.

Colorectal cancer (CRC) is a complex and multifactorial disease, in which genetic and environmental factors both seem to play a part. Many epidemiological studies have explored the association between genetic polymorphisms of X-ray repair cross-complementing group 3 (XRCC3) (Thr241Met) and Xeroderma pigmentosum group D (XPD) lysine to glutamine at codon 751 (Lys751Gln) and risk of CRC in various populations; however, the results are controversial. We conducted this case-control study in a West Algerian population to assess the potential role of this genetic polymorphism on the risk of CRC in this population.

First molecular analysis of F8 gene in algeria: identification of two novel mutations.

The aim of this study was to detect the genetic alterations in the Factor 8 gene in 26 patients from Western Algeria. We detected the presence of "intron 22 inversion" with long-range polymerase chain reaction (PCR). Negative patients for this inversion were analyzed for "intron 1 inversion" using multiplex PCR.
