How germline genes promote malignancy in cancer cells
BioEssays, Volume 45, Issue 1, January 2023., 2023 We hypothesize that activation of a “germline program” promotes oncogenesis. Expression of otherwise germline specific genes may result in pseudomeiotic activity, thereby promoting oncogenesis through genomic instability. Other processes that are differentially regulated in the germline, such as migration and epigenetic – and metabolic plasticity, may ...

Sperm competition and sperm midpiece size: no consistent pattern in passerine birds [PDF]
, 2007 Sperm competition is thought to be a major force driving the evolution of sperm shape and function. However, previous studies investigating the relationship between the risk of sperm competition and sperm morphometry revealed inconclusive results and ...

Sperm-hybrid micromotor for drug delivery in the female reproductive tract [PDF]
ACS nano (2017), 2017 A sperm-driven micromotor is presented as cargo-delivery system for the treatment of gynecological cancers. This particular hybrid micromotor is appealing to treat diseases in the female reproductive tract, the physiological environment that sperm cells are naturally adapted to swim in.

Human sperm steer with second harmonics of the flagellar beat [PDF]
Nat. Commun. 8, 1415 (2017), 2017 Sperm are propelled by bending waves travelling along the flagellum. During steering in gradients of sensory cues, sperm adjust the flagellar beat waveform. Symmetric and asymmetric beat waveforms produce straight and curved swimming paths, respectively.
