Abstract

The Bdnf (brain-derived neurotrophic factor) gene contains eight regulatory exons (I–VIII) alternatively spliced to the protein-coding exon IX. Only exons I, II, IV, and VI are relatively well studied. The BDNF system and brain serotonergic system are tightly interconnected and associated with aggression. The benzopentathiepine TC-2153 affects both systems and exerts antiaggressive action. Our aim was to evaluate the effects of TC-2153 on the Bdnf exons I–IX’s expressions and serotonin receptors’ mRNA levels in the brain of rats featuring high aggression toward humans (aggressive) or its absence (tame). Aggressive and tame adult male rats were treated once with vehicle or 10 or 20 mg/kg of TC-2153. mRNA was quantified in the cortex, hippocampus, hypothalamus, and midbrain with real-time PCR. Selective breeding for high aggression or its absence affected the serotonin receptors’ and Bdnf exons’ transcripts differentially, depending on the genotype (strain) and brain region. TC-2153 had comprehensive effects on the Bdnf exons’ expressions. The main trend was downregulation in the hypothalamus and midbrain. TC-2153 increased 5-HT1B receptor hypothalamusc mRNA expression. For the first time, an influence of TC-2153 on the expressions of Bdnf regulatory exons and the 5-HT1B receptor was shown, as was an association between Bdnf regulatory exons and fear-induced aggression involving genetic predisposition.

  • In Novosibirsk, Russia, a research group has bred 90 generations of gray Norway rats selectively for either tameness or high aggression towards a human experimenter's hand.

    “In Novosibirsk, Russia, a research group has bred 90 generations of gray Norway rats selectively for either tameness or high aggression towards a human experimenter’s hand (Moskaliuk et al. 2023).”

    From Decoding the bidirectional links between alcohol misuse and aggression: toward a unified translational framework (2026) · cites this paper as Moskaliuk et al. 2023

    The Introduction and Materials and Methods §4.1 state that wild Norway rats were selectively bred for 90 generations in Novosibirsk for absence or enhancement of aggression toward humans. Our copy does not specify that selection was based on responses to an experimenter’s hand. (LLM, conf=0.86)

  • These selectively bred lines display distinct behavioral phenotypes and differences in relevant neurobiology like monoamine systems.

    “These lines not only display distinct behavioral phenotypes, but also differences in relevant neurobiology like monoamine systems (Zhukov et al. 2022; Moskaliuk et al. 2023; Pravikova et al. 2024).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
