Henckelia incana is an endemic medicinal plant used for the treatment of fever and skin allergy. In the present study shoot regeneration was evaluated on Murashige and Skoog's (MS) medium supplemented with auxins, Indole-3-acetic acid (IAA), Indole-3- butyric acid (IBA), 1-Naphthaleneacetic acid (NAA), 2, 4-Dichlorophenoxyacetic acid (2, 4-D) and cytokinins, 6-Benzylaminopurine (BAP) and Kinetin (Kn) at concentrations of 0.5, 1.0, 2.0, 3.0, 4.0 and 5.0 mgl(-1). MS medium with IBA (18.08), NAA (17.83) and IAA (17.58) at 0.5 mgl(-1) concentrations showed efficient regeneration. Regenerated shoots were rooted on half-strength MS medium with and without 0.5 mgl(-1) IBA or NAA. The plantlets were successfully hardened in rooting trays (peat, vermiculite and sand) and transferred to field mileu. The genetic fidelity of in vitro raised plants was assessed by using three different single primer amplification reaction (SPAR) markers namely random amplified polymorphic DNA (RAPD), inter-simple sequence repeat (ISSR) and direct amplification of mini-satellite DNA region (DAMD). The results consistently demonstrated true-to-true type propagation. This is the first report of in vitro propagation and establishment of true-to-true type genetic fidelity in H. incana.

Alternative splicing impacts most multi-exonic human genes. Inaccuracies during this process may have an important role in ageing and disease. Here, we investigate splicing accuracy using RNA-sequencing data from >14k control samples and 40 human body sites, focusing on split reads partially mapping to known transcripts in annotation.

The variability in translational models profoundly impacts the outcomes and predictive value of preclinical studies for gastrointestinal (GI) cancer treatments. Preclinical models, including 2D cell cultures, 3D organoids, patient-derived xenografts (PDXs), and animal models, provide distinct advantages and limitations in replicating the complex tumor microenvironment (TME) of human cancers. Each model's unique biological and structural differences contribute to discrepancies in treatment responses, challenging the direct translation of experimental results to clinical settings.

Objectives: Many cancer cells depend on exogenous methionine for proliferation, whereas non-tumorigenic cells can divide in media supplemented with the metabolic precursor homocysteine. This phenomenon is known as methionine dependence of cancer or methionine addiction. The underlying mechanisms driving this cancer-specific metabolic addiction are poorly understood.

The fidelity of immune responses depends on timely controlled and selective mRNA degradation that is largely driven by RNA-binding proteins (RBPs). It remains unclear whether stochastic or directed processes govern the selection of an individual mRNA molecule for degradation. Using human and mouse cells, we show that tristetraprolin (TTP, also known as ZFP36), an essential anti-inflammatory RBP, destabilizes target mRNAs via a hierarchical molecular assembly.

Hair cells in the mammalian cochlea are highly vulnerable to damage from drug toxicity, noise exposure, aging, and genetic mutations, with no capacity for regeneration. Progress in hair cell protection research has been limited by the scarcity of cochlear tissue and suitable in vitro models. Here, we present a novel one-step, self-organizing inner ear organoid system optimized with small molecules, which bypasses the need for multi-step expansion and forced differentiation protocols.
