Deciphering the skeletal interoceptive circuitry to control bone homeostasis
This review introduces the skeletal interoceptive circuitry, covering the ascending signals from bone tissues to the brain (sensors), the central neural circuits that integrate this information and dispatch commands (CPU), and the descending pathways that regulate bone homeostasis (effectors).

No effects of androgen receptor gene CAG and GGC repeat polymorphisms on digit ratio (2D:4D): Meta-analysis [PDF]
Objectives: A series of meta-analyses assessed whether differentially efficacious variants (CAG and GGC repeat-length polymorphisms) of the human androgen receptor gene are associated with digit ratio (2D:4D), a widely investigated putative pointer to prenatal androgen action.

Testosterone and the brain [PDF]
Gender differences in spatial recognition, and age-related declines in cognition and mood, point towards testosterone as an important modulator of cerebral functions. Testosterone appears to activate a distributed cortical network, the ventral processing stream, during spatial cognition tasks, and addition of testosterone improves spatial cognition in ...

Steroid photoreactivity was a major topic in the last century. This study revisits it by exploring the photochemistry of Δ1‐keto‐steroids, offering an efficient method to modify the classic steroid 6/6/6/5 ring system. This approach enables the transformation of accessible steroids into rare ones, demonstrated by synthesizing 5,6‐dihydro‐ophiopogonol A

ABSTRACT Hypophosphatasia (HPP), caused by loss‐of‐function mutations in the ALPL gene encoding tissue‐nonspecific alkaline phosphatase (TNAP), is characterized by skeletal and dental hypomineralization that can vary in severity from life‐threatening to milder manifestations only in adulthood.

Mouse testicular macrophages can independently produce testosterone and are regulated by Cebpb
Background Testicular macrophages (TM) have long been recognized for their role in immune response within the testicular environment. However, their involvement in steroid hormone synthesis, particularly testosterone, has not been fully elucidated.

Highly‐selective Electrochemical Decarboxylative Late‐Stage Functionalization of Amino Acids
A unified electrochemical decarboxylative strategy for the site‐selective construction of carbon‐heteroatom bonds is disclosed herein. The metal‐ and catalyst‐free decarboxylation provides access to functionalization of C‐ and N‐terminus from simple amino acid feedstock.

Sexing Bones: Improving Transparency of Sex Reporting to Address Bias Within Preclinical Studies
ABSTRACT Despite knowledge that sexually dimorphic mechanisms regulate bone homeostasis, sex often remains unreported and unconsidered in preclinical experimental design. Failure to report sex could lead to inappropriate generalizations of research findings and less effective translation into clinical practice.

Testosterone and androstanediol glucuronide among men in NHANES III
Background Most of the androgen replacement therapies were based on serum testosterone and without measurements of total androgen activities. Whether those with low testosterone also have low levels of androgen activity is largely unknown.

ABSTRACT Age‐related bone loss is a failure of balanced bone turnover and diminished skeletal mechanoadaptation. Estrogen receptors, ERα and ERβ, play critical roles in osteoprotective regulation activated by estrogen and mechanical signals. Previous studies mainly focused on ERα and showed that osteocyte‐ERα (Ot‐ERα) regulated trabecular, but not ...
