Salivary microbiota dysbiosis and elevated polyamine levels contribute to the severity of periodontal disease.

Background: The oral cavity is a complex environment which harbours the second largest and most diverse microflora after the gastrointestinal tract. The bacteriome in the oral cavity plays a pivotal role in promoting the health and well-being of human beings. Gingivitis, an inflammation of the gingival tissue, arises due to plaque accumulation on the teeth, often leads to periodontitis.

Thermal tolerance role of novel polyamine, caldopentamine, identified in fifth instar Bombyx mori.

Silkworms have limited ability to regulate their body temperature; therefore, environmental changes, such as global warming, can adversely affect their viability. Polyamines have shown protection to various organisms against heat stress. This study evaluated the qualitative and quantitative changes in heat-stressed Bombyx mori larvae polyamines.

Spermidine alleviates heat shock and promotes the growth of Bombyx mori.

Silkworms have limited ability to regulate their body temperature upon exposure to varying atmospheric temperatures. Environmental changes, such as global warming, adversely affect silkworm viability. Spermidine, a polyamine, protects various organisms against heat stress.

Dynamics of nuclear matrix attachment regions during 5 instar posterior silk gland development in Bombyx mori.

Background: Chromatin architecture is critical for gene expression during development. Matrix attachment regions (MARs) control and regulate chromatin dynamics. The position of MARs in the genome determines the expression of genes in the organism.

Nuclear matrix associated RNAs in posterior silk glands show developmental dynamics in Bombyx mori in 5th instar larvae.

Objectives: The nuclear matrix maintains and regulates chromatin structure. RNA is an integral component of the nuclear matrix and is essential to its structural maintenance. Bombyx mori is a major economic contributor in the sericulture industry and produces fibroin-the most important silk protein in its posterior silk glands during 5th instar larval stage.

Nuclear matrix associated RNA datasets of posterior silk glands of Bombyx mori during 5th instar larval development.

Objectives: Bombyx mori is the key contributor to industrial silk production. The maximum production of silk occurs during 5th instar. The posterior silk glands in the larvae are responsible for the production of the main component of silk fibre-fibroin.

16S rRNA sequence data of Bombyx mori gut bacteriome after spermidine supplementation.

Objectives: The silkworm Bombyx mori (B. mori) is an important domesticated lepidopteran model for basic and applied research. They produce silk fibres that have great economic value.
